[0017] FIG. 1 is a flowchart of a method for determining an icon position according to an exemplary embodiment. As shown in FIG. 1, the method for determining an icon position includes the following steps.
[0018] S101: detecting a target object in a target image and determining a reference position of the target object in the target image.
[0019] In some embodiments, the target image refers to an image to be added with an icon. The target image may include a video image, a static image, etc., and the icon to be added to the target image may include an opaque or a semi-transparent mark such as caption text, floating image, watermark, etc. A target object is generally included in the target image, and the target object may be any object, such as human, animal, article, plant, etc., included in the image. In some embodiments, the target object in the target image may be detected by using the Faster Regions with Convolutional Neural Networks features (Faster-RCNN) algorithm, Single Shot MultiBox Detector (SSD) algorithm, etc., and embodiments of the application do not specifically limit the detection method. After the detection is completed, zero, one or more rectangular boxes are generally output according to the detection result, so as to frame the target object. The center position of the rectangular box or the position corresponding to a certain feature of the object in the rectangular box is selected as the reference position of the target obj ect.
[0021] In some embodiments, the saliency detection can be performed on the target image. The saliency detection is a technology that calculates the saliency of an image by analyzing the characteristics such as color, intensity and direction of the image to generate a saliency map. The salient point of an image refers to a pixel (or region) in the image which can be distinguished from other pixels (or regions) to attract the visual attention. For example, if there is a black spot on a piece of white paper, the saliency of the black spot is higher, and the saliency is lower in other places. The saliency map is a two-dimensional image with the same size as the original image, wherein the value of each pixel represents the magnitude of the saliency of the corresponding point of the original image. The saliency map may be used to guide the selection of the attention area and quickly locate the saliency area of the image. The saliency detection may be performed on the target image by using the Minimum Barrier Salient (MBS) algorithm.
[0022] S103: selecting an icon position from preset candidate positions according to distances between the reference position or the salient location and the candidate positions.
[0023] In some embodiments, the preset candidate position is a predetermined floating position of the icon on the target image, and there are generally multiple candidate positions. For example, the candidate positions may include the center, upper center, lower center, left center, right center, upper left corner, upper right corner, lower left corner, and lower right corner of the target image. The Euclidean distances between each reference position obtained in S101 and the candidate positions are calculated, the Euclidean distances between the salient location obtained in S102 and the candidate positions are calculated, and one or more candidate positions are selected as the icon position based on these distances.
[0024] Specifically, in order to prevent the icon from occluding key objects in the image, the candidate position with the largest Euclidean distance may be selected as the icon placement position.
[0025] In the embodiments of the application, the target object in the target image is detected and the reference position of the target object in the target image is determined, and the salient location in the target image is detected, so as to obtain the reference position of the more significant object or article in the target image and the salient location that may be paid more attention in the target image. Finally the icon position is selected from preset candidate positions according to the distances between the reference position or the salient location and the candidate positions, so as to prevent the icon from occupying the reference position and the salient location. This method does not require the manual operation at all and has the higher efficiency.
[0026] FIG. 2 is a flowchart of another method for determining an icon position according to an exemplary embodiment, which is an optional embodiment of the method in FIG. 1. As shown in FIG. 2, the method for determining an icon position includes the following steps.
[0028] In some embodiments, the objects in the target image are firstly identified. For example, the face detection, cat and dog detection, article detection, and even more refined facial feature point detection are performed on the target image. Zero, one or more rectangular boxes are generally output according to the detection results. The rectangular box is the target area and is used to frame the target object.
[0029] FIG. 3 is a schematic diagram of determining the icon position in a target image according to an exemplary embodiment. A little boy 01, a little girl 02, and a seesaw 03 are in FIG. 3. Through the image detection, three objects in the target image are identified: little boy 01, little girl 02 and seesaw 03; and three corresponding target areas are output: the target area S1 corresponding to the face of the little boy 01, the target area S2 corresponding to the face of the little girl 02, and the target area S3 corresponding to the fulcrum of the seesaw 03.
[0031] In some embodiments, the most critical object is selected from at least one object identified in the target image according to the preset rule. For example, it is possible to select the largest object, or one of several closest objects, or the smallest object, etc.
[0033] A1: determining the target object according to a position/positions of the at least one object in the target image.
[0034] Specifically, the location area of each object in the target image is determined, and the target object is determined according to the location area. For example, the location areas are divided into the center, upper center, lower center, left center, right center, upper left corner, upper right corner, lower left corner, lower right corner, etc., and then an object in a certain location area is determined as the target object. For example, the little boy 01 located in the upper center may be determined as the target object in FIG. 3.
[0035] A2: determining the target object according to the area proportion of the at least one object in the target image.
[0036] Specifically, the target object may be determined according to the area proportion of the target area corresponding to each object. For example, the object with the maximum area proportion or the object with the minimum area proportion may be determined as the target object. For example, the seesaw 03 of which the target area has the maximum area proportion may be taken as the target object.
[0037] S203: taking the target position of the target area as the reference position according to the target object, wherein the target position includes: a center of the target area, and a position of a target feature in the target area.
[0038] In some embodiments, after the target object is determined, the target position may be selected as the reference position from the target area corresponding to the target object according to a preset rule. The preset rule may be to select the center of the target area as the reference position, or to select another specific position of the target area as the reference position. Alternatively, the preset rule may be to select the position of a target feature in the target area, for example, to select the position of the human eye or the position of the human nose or the like in the target area. Here, the specific element included in the target feature is not specifically limited in the embodiments of the application, and can be preset by those skilled in the art according to requirements.
[0039] For example, in FIG. 3, after the target object is determined as the little boy 01, the position S11 of the human nose in S1 is selected as the reference position for the target area S1 corresponding to the little boy 01.
[0040] In some embodiments, the target area where the object in the target image is located is identified, and the target position is selected at the center of the target area or the position of the target feature. The target position is the position of the key part of the target object. For the subsequent selection of the icon position, the above target position can be omitted.
[0042] In some embodiments, if the reference position of the target image does not exist, the salient location of the target image may be obtained. To obtain the salient location, the grayscale image corresponding to the target image may be firstly obtained. The grayscale image is one in which the value of each pixel is a single sample representing only an amount of light, where the contrast ranges from black at the weakest intensity to white at the strongest. The grayscale image is different from the black and white image, and the grayscale image has many shades of gray between black and white. The grayscale image may be obtained by measuring the brightness of each pixel in the target image in a single electromagnetic wave spectrum such as visible light.
[0043] The purpose of obtaining the grayscale image corresponding to the target image is to perform the saliency detection on the target image, but it is generally believed that the target object in the image is more important than the saliency area in the image. Thus, if the reference position is detected, there is no need to perform the saliency detection, that is, there is no need to perform the step S204 to step S206 in the embodiment of the application.
[0044] S205: determining a salient area according to the grayscale information of different areas in the grayscale image.
[0045] The grayscale image includes a plurality of grayscale areas, and each area has the corresponding grayscale information which represents the shades of gray in this area. The salient area in the grayscale image may be determined according to the grayscale information corresponding to each area. The salient point of an image refers to a pixel (or region) in the image which can be distinguished from other pixels (or regions) to attract the visual attention. Therefore, the area in the grayscale image with the grayscale value being most different from that of other areas may be determined as the salient area. For example, if the grayscale value of the area S21 where the right eye of the little girl 02 is located has the largest difference from the grayscale values of other areas in the grayscale image after the Figure 3 is converted into a grayscale image, then the area S21 is determined as the salient area.
[0047] After the salient area is determined, the center of the salient area is selected as the salient location.
[0048] For example, the center S22 of the area S21 may be determined as the salient location in FIG. 3.
[0049] Since the salient location is a position in the image that can attract more visual attention, the subsequent selection of the icon position can omit the salient location, to avoid the influence of the icon on the user's visual attention area in the target image.
[0050] S207: selecting a candidate position with the largest distance from the reference position as the icon position if the reference position exists but the salient location does not exist.
[0051] In some embodiments, if the target object in the target image is detected and the reference position of the target object is determined but the salient location of the target image does not exist because the grayscale information of the target image has little difference, then the candidate position farthest from the reference position is selected as the floating position of the icon. Here the candidate positions may include the center, upper center, lower center, left center, right center, upper left corner, upper right corner, lower left corner, and lower right corner of the target image. The above distance may be Euclidean distance, i.e., the distance between the center of the reference position and the center of the candidate position.
[0052] For example, in FIG. 3, if the salient location does not exist and the position S11 of the nose of the little boy S1 is the reference position, then the Euclidean distance between the center S12 of the reference position and the center of each candidate position is calculated. Through the calculation, the Euclidean distance between point S12 and the candidate position of the lower right corner 04 is the largest, so the candidate position at the lower right corner 04 is selected as the icon position.
[0053] S208: selecting a candidate position with the largest distance from the salient location as the icon position if the salient location exists but the reference position does not exist.
[0054] In some embodiments, if no object can be detected in the target image, it means that the target image has no reference position. While the grayscale image corresponding to the target image has a salient location, then the candidate position with the largest distance from the salient location is selected as the icon position. Specifically, the distance between the center of the salient location and the center of each candidate position is calculated.
[0055] For example, in FIG. 3, if the reference position does not exist and the center S22 of the position S21 corresponding to the eyes of the little girl S2 is the salient location, then the Euclidean distance between the point S22 and the center of each candidate position is calculated. Through the calculation, the Euclidean distance between point S22 and the candidate position at the lower left corner 05 is the largest, then the candidate position at the lower left corner 05 is selected as the icon position.
[0056] S209: selecting a candidate position with both distances from the reference position and the salient location greater than a preset distance threshold and with the largest average distance as the icon position if both the reference position and the salient location exist, wherein the average distance is an average of the distances between the candidate position and the reference position and the distance between the candidate position and the salient location.
[0057] In some embodiments, if both the reference position and the salient location exist, then the first distance between the reference position and each candidate position and the second distance between the salient location and each candidate position may be calculated respectively. At least one candidate position with both the first distance and the second distance greater than the preset distance threshold are obtained. For at least one such candidate position, the average of the first distance and the second distance is calculated to obtain at least one average distance, and the candidate position with the largest average distance is taken as the icon position.
[0058] Moreover, if both the reference position and the salient location exist, one of them may also be selected for determining the icon position according to the actual application. For example, the candidate position with the largest distance from the reference position is selected as the icon position, or the candidate position with the largest distance from the salient location is selected as the icon position.
[0059] In the above steps 208 to 209, the candidate position with the largest distance from the reference position or with the largest distance from the salient location or with the largest average distance is selected as the icon position, so that the floating position of the icon is far away from the area where the key object in the target image is located, avoiding the influence of the icon on the picture display effect.
[0060] In addition to the beneficial effects of the method for determining an icon position in FIG. 1, embodiments of the application also identifies the target area where an object in the target image is located and selects the target position at the center of the target area or the position of the target feature, where the target position is the position of the key part of the target object. Meanwhile, the salient location is determined according to the grayscale image corresponding to the target image, where the salient location is the position in the target image that can attract more visual attention. The candidate position with the largest distance from the reference position or with the largest distance from the salient location or with the largest average distance from the reference position and the salient location is selected as the icon position, so that the floating position of the icon is set far away from the area where the key object in the target image is located, avoiding the influence of the icon on the picture display effect. This solution determines the floating position of the icon without manual operation in the case of fully considering the reference position and the salient location of the target image, and the selected position is more accurate.
