Abstract (en)
[origin: WO2019203920A1] Described is a system for bounding box generation. The system operates on an image comprised of pixels having a one-bit value per pixel. Bounding boxes are generated around connected components in the image, the connected components having pixel coordinate and pixel count information. A ranking score is generated for each bounding box based on the pixel coordinate and pixel count information. The bounding boxes are filtered to remove bounding boxes that exceed a predetermined size and pixel count based on the pixel coordinate and pixel count information. The bounding boxes are further filtered to remove bounding boxes that fall below a predetermined ranking score, resulting in remaining bounding boxes. Finally, a device can be controlled or otherwise operated based on the remaining bounding boxes.
