Abstract
We propose measures to evaluate the performance of video object segmentation and tracking methods quantitatively without ground-truth segmentation maps. The proposed measures are based on spatial differences of color and motion along the boundary of the estimated video object plane and temporal differences between the color histogram of the current object plane and its neighbors. They can be used to localize (spatially and/or temporally) regions where segmentation results are good or bad; and/or combined to yield a single numerical measure to indicate the goodness of the boundary segmentation and tracking results over a sequence. The validity of the proposed performance measures <i>without ground truth </i>have been demonstrated by canonical correlation analysis of the proposed measures with another set of measures it <i>with ground-truth</i> on a set of sequences (where ground truth information is available). Experimental results are presented to evaluate the segmentation maps obtained from various sequences using different segmentation and tracking algorithms.
