In previous techniques of bit rate reduction transcoding, reusing the mode of the input MB is widely adopted. However, directly re-using the mode of input MB will cause additional losses for H.264 bit-rate scaling. Variable-size block-matching based motion estimation makes H.264 much more efficient than other coding standards while increasing its complexity. As the target bit rate changes, the ...

Block-based connected components labeling is by far the fastest algorithm to label the connected components in 2D binary images, especially when the image size is quite large. This algorithm produces a decision tree that contains 211 leaf nodes with 14 levels for the depth of a tree and an average depth of 1.5923. This article attempts to provide a faster method for connected components labelin...

The latest H.264/AVC video compression standard promises significantly higher compression efficiency than prior standards. H.264/AVC achieves coding gains through a rich set of advanced coding tools including variable block size motion compensation, quarter-pel motion compensation and long-term memory motion compensation [1]. However, with so many coding options available, it has become extreme...

Most of the traditional medical applications are insecure and difficult to compute data integrity with variable hash size. Traditional security systems it depend on static parameters for security. Also, distributed based cloud storage independent computational due unstructured memory. As size its dimensions increasing in public private servers, is provide machine learning privacy preserving com...
