摘要
针对人眼对亮度与色度信号分辨力的差异,文章采用亮度和色度分离压缩的算法,并提出把两个色度平面视为色度空间的二维矢量,利用分形插值,在低分辨空间作统一分形编码。实验结果表明,无论在压缩比还是编码复杂度上都取得了良好的效果。
: By taking into account the different resolving power between luminance and chromaticity,we use the compression algorithm of separative luminance/chromaticity,and suggest that two chromaticity planes can be regarded as 2-D vector of the chromatic space,wherein the fractal coding in the low resolution space can be realized through fractal interpolation.Experimental results show that this new approach produces a good effect both in the compression ratio and in the encoding complexity.
