Abstract (en)

[origin: CN115335920A] Histopathologic scoring can be based on regions of certain types of cells identified by bioassays or expression of genotypic or phenotypic features of these cells. Automated scoring process using an image analysis algorithm includes correct delineation of a region of interest, this process being referred to as segmentation. This system and method accomplishes such segmentation using a generative adversarial network trained to generate a mask covering each region of interest. The present invention can perform both segmentation and classification by using a separate image band for each classification. By interpreting individual image bands for each region, a scoring algorithm may utilize, for example, classification of tumor regions and immune cell stained regions. Classification problems with more image bands will use images with equal number of image bands. There is no limitation on the number of image bands that the image can encode for each pixel.
