Abstract: An intra-class discriminator-based method for weakly supervised image semantic segmentation, a system, and an apparatus, which aim to solve the problem of inaccurate semantic segmentation caused by coarse labeling used for weak supervision. The present method comprises: for each image level class, constructing two levels of intra-class discriminators, which are used for determining whether each pixel of the corresponding image class belongs to a target foreground or background, and using weak supervision data to perform training; on the basis of image class labels for pixel levels generated by the intra-class discriminators, generating a semantic segmentation result and outputting said result; said labels may further be used to perform training for an image semantic segmentation module or network, and obtaining a semantic segmentation model ultimately used for an unlabeled input image. The present method abundantly mines intra-class image information implicit in feature coding, accurately distinguishes foreground and background pixels, and significantly improves the performance of a weakly supervised semantic segmentation model when only image level labeling is relied upon.
