Abstract:

In order to obtain the initial video objects from the video sequences, an improved initial video object extraction algorithm based on motion connectivity is proposed.Moving objects in video sequences are highly connected and structured, which makes motion connectivity an advanced feature for segmentation.Accordingly, after sharp noise elimination, the cumulated difference image, which exhibits the coherent motion of the moving object, is adaptively thresholded.Then the maximal connected region is labeled, post-processed and output as the final segmenting mask.Hence the initial video object is effectively extracted. Comparative experimental results show that the proposed algorithm extracts the initial video object automatically, promptly and properly, thereby achieving satisfactory subjective and objective performance.
