Traditionally, land-cover mapping from remote sensing images is performed by classifying each atomic region in the image in isolation and by enforcing simple smoothing priors via random fields models as two independent steps. In this paper, we propose to model the segmentation problem by a discriminatively trained Conditional Random Field (CRF). To this end, we employ Structured Support Vector Machines...
We address the problem of semantic segmentation: classifying each pixel in an image according to the semantic class it belongs to (e.g. dog, road, car). Most existing methods train from fully supervised images, where each pixel is annotated by a class label. To reduce the annotation effort, recently a few weakly supervised approaches emerged. These require only image labels indicating which classes...
We present a novel technique for figure-ground segmentation, where the goal is to separate all foreground objects in a test image from the background. We decompose the test image and all images in a supervised training set into overlapping windows likely to cover foreground objects. The key idea is to transfer segmentation masks from training windows that are visually similar to windows in the test...
