Novel YUV 8bpp subsampling pattern
2010 Conference Record of the Forty Fourth Asilomar Conference on Signals Systems and Computers, 2010Co-Authors: Sergio Goma, Mickey AleksicAbstract:We propose a novel 8bpp subsampling YUV pattern based on a checkerboard subsampling of the luminance component that explicitly preserves the edge. The proposed pattern uses 1bit to encode edge direction in the missing luminance pixel and this bit is stored in the Chroma Sample as the Chroma Sample is DPCM encoded 8 to 7bits per Sample. The complexity analysis of both encoder and decoder is concluded with a proposed hardware implementation. The image quality performance of the proposed pattern is estimated using MTF measurements, quantifying the loss in high-frequencies and a comparison is presented across the YUV subsampling methods.
