METHOD FOR TRACKING AND SEGMENTING A TARGET OBJECT IN AN IMAGE USING MARKOV CHAIN, AND DEVICE USING THE SAME

摘要

A method for tracking a target object in frames of video data using Absorbing Markov Chain (AMC), including steps of: (a) acquiring a bounding box containing the target object in a current frame and a segmentation result for the target object in a previous frame; (b) obtaining obtain a region of interest (ROI) in the current frame by enlarging the bounding box to contain a portion of background information surrounding the target object; (c) acquiring information on local regions within the ROI in the current frame; (d) constructing an AMC graph using at least part of the local regions within the region of interest (ROI) in the current frame and local regions within a region of interest (ROI) in the previous frame; and (e) acquiring a segmentation result for the target object within the current frame by thresholding individual nodes in the AMC graph using absorption times thereof.
