Seishi Takamura and Atsushi Shimizu: Image Coding Using Nonlinear Evolutionary Transforms. Data Compression Conference (DCC 2013), pp. 521-521, 20-22 March 2013.



Transform is one of the most important tools for image/video coding technology. In this paper, novel nonlinear transform generation based on genetic programming is proposed and implemented into H.264/AVC and HEVC reference software to enhance coding performance. The transform procedure itself is coded and transmitted. Despite this overhead, 0.590% (vs. JM18.0) and 1.711% (vs. HM5.0) coding gain was observed in our preliminary experiment.
