Coding efficiency evaluation of RVLC codes

Variable length coding (VLC) has become an important part of visual compression standards such as JPEG, MPEG, and H.26x, Recently, reversible variable length coding is being used to improve the robustness against bit errors. The coding efficiency performance of different reversible VLC (RVLC) schemes depends on several factors such as source distribution, quantizer step, and codeword length distribution. In this paper, we develop a mathematical approach to calculate the efficiency of RVLC code table for coding symbols with generalized Gaussian distribution.
