Performance and computational complexity optimization in a configurable video coding system

Most standard video coders have high computational complexity in order to achieve high performance in terms of compression ratio. In this paper, a configurable coding scheme is analyzed with respect to the computational complexity and distortion. The major coding modules are analyzed in terms of computational complexity and distortion in the H.263 video coding framework. Based on the analyzed data, operational C-D curve is obtained through an exhaustive search and Lagrangian multiplier method. It is shown that an optimally chosen operational mode makes a significant difference.
