Abstract
System and methods for object segmentation include providing a pre-trained neural network model to segment object instances based on a first set of images and a first loss function. The neural network, for a pixel, can generate a gradient flow that points towards a center of an object structure and provides a probability score indicating a probability of the pixel belonging to the object structure. An adapted neural network model can be generated from the pre-trained neural network model to account for domain shifted new input images by training the pre-trained neural network model on a second set of images and a loss function that comprises a contrastive flow loss component and a contrastive mask loss component.
