JCTVC-B033 [K. Iwata, S. Mochizuki, R. Hashimoto (Renesas)] Intra prediction based on repetitive pixel replenishment
The contribution reports improved performance results of intra prediction based on repetitive pixel replenishment. The simulation results showed that predicted image created by the method had an average of 1.14 dB and up to 2.76 dB PSNR gain for luminance against anchor of CfP. These results also showed an average of 1.32 dB, 1.54 dB and up to 3.58 dB, 3.55 dB PSNR gain for chrominance, respectively. The proposed method is implemented on Test model under consideration (TMuC) software.
Usage of template matching. Search range is 33 samples horizontally and 16 samples vertically Prediction. Full search is used, Prediction is composed from two best candidates (i.e. roughly 500 operations per sample is necessary at encoder, displacement vector is encoded).
Result only for two sequences Basketball and BQMall 4.78 and 4.0 % bitrate reduction for intra only coding (basis for simulation is TMuC 0.1).
Further study was encouraged, more complete results are necessary to figure out the merits.
