Abstract
A method of image segmentation includes receiving one or more images, determining a loss component, for each pixel one image of the one or more images, identifying a majority class and identify a cross-entropy loss between a network output and a target, randomly selecting pixels associated with the one image and select a second set of pixels to compute a super pixel loss for each pair of pixels, summing corresponding loss associated with each pair of pixels, for each corresponding frame of the plurality of frames of the image, computing a flow loss, a negative flow loss, a contrastive optical flow loss, and a equivariant optical flow loss, computing a final loss including a weighted average of the flow loss, the cross entropy loss, the super pixel loss, and foreground loss, updating a network parameter and outputting a trained neural network.
