Abstract
A method, comprising: receiving a video comprising video frames as an input; generating set of object proposals from the video; generating object tracklets comprising regions appearing in consecutive frames of the video, said regions corresponding to object proposals with a predetermined level of confidence; constructing a graph comprising the object proposals and superpixels grouped from the pixels of the frame; calculating a first cost function for superpixel likelihoods in terms of the object proposals in an object tracklet; calculating a second cost function for object proposal likelihoods in terms of the superpixels in the frame; minimizing the first and the second cost function with each other; computing posterior probabilities of each superpixel; and assigning each superpixel with an object class with a maximum posterior probability to constitute semantic object segmentation.
