Transform Domain Wyner-Ziv Video Coding (TDWZ) is one of the most popular paradigms of Distributed Video Coding (DVC) which supports low encoding complexity. However, there is still a gap in its coding performance compared to conventional video coding standards such as MPEG-x, or H.264/AVC. In order for TDWZ to reach comparable performance to them, a good method for deciding a proper Group of Picture (GOP) size is in great necessity. From this point of view, we propose an iterative algorithm which efficiently determines GOP size based on an intra mode decision method at frame level. This approach firstly constructs a coarse GOP size and then refines it by iterative checking for final GOP size. Experimental results show superiority of the proposed algorithm with improvement up to 2dB in term of coding efficiency.
