An optimal mode selection algorithm for scalable video coding
Scalable video coding (SVC) is extended from its predecessor advanced video
coding (AVC) because of its flexible transmission to all type of gadgets.
However, SVC is more flexible and scalable than AVC, but it is more complex in
determining the computations than AVC. The traditional full search method in
the standard H.264 SVC consumes more encoding time for computation. This
complexity in computation need to be reduced and many fast mode decision (FMD)
algorithms were developed, but many fail to balance in all the three measures
such as peak signal to noise ratio (PSNR), encoding time and bit rate. In this
paper, the proposed optimal mode selection algorithm based on the orientation
of pixels achieves better time saving, good PSNR and coding efficiency. The
proposed algorithm is compared with the standard H.264 JSVM reference software
and found to be 57.44% time saving, 0.43 dB increments in PSNR and 0.23%
compression in bit rate.Comment: 14 pages, 1 figur
