Class Specific Segmentation

In this work we address the task of learning how to segment a particular class of objects, by means of a training set of images and their segmentations. In particular we propose a  method to overcome the extremely high training time of a previously proposed solution to this problem, Kernelized Structural Support Vector Machines.We employ a one-class SVM working with joint kernels to robustly learn significant support vectors (representative image-mask pairs) and accordingly weight them to build a suitable energy function for the graph cut framework. We report results obtained on two public datasets and a comparison of training times on different training set sizes.
