An Interframe Coding Method Using Block-Based Segmentation of Motion Field[J]. Journal of Image and Graphics, 1998, 3(1): 7. DOI: 10.11834/jig.19980104.
This paper proposed a contour/texture-based inter-frame coding method
BBSMF
which is suited for low bit-rate video coding. The BBSMF method first segments an image into some homgeneous regions
and generates variable size blocks to approximate these regions; Then it applies motion detection technique to separate the image into moving regions and still regions
the moving regions are estimated to get motion information by which a motion field image is constructed; Finally
the motion field image is segmented
the contours and the motion mean errors of textures are coded. Computer simulation shows that the BBSMF method gives better performance than the H.261 method in terms of not only CR but PSNR and subjective quality of reconstruction images. In this paper
some discussions are also made on subsample coding
motion compensation of moving scenes and how to select the number of predicted frames
