摘要
针对某中分辨率成像光谱仪遥感图像数据的特点,在研究基于局域纹理特征适合空间应用图像无损压缩技术的基础上,进行无损解压缩算法的设计,阐述了如何采用并行处理和流水线技术优化算法,实现算法到VLSI结构的优化映射,研制无损解压缩专用芯片,该芯片可以不低于16 Mbps的速率实时处理压缩数据,进行无损解压.
In this paper, in uiew of the feature of the compressed data of the MODIS, a new lossless image data compression algorithm named lossless image compression based on feature of local texture is presented and decompression algorithm is designed. It is mainly described in this paper that how the corresponded VLSI architecture is proposed by using the technique of parallel processing and pipe-line. The special integrated circuit of lossless data decompression has been manufactured. This card can decompress data realtimely and losslessly at the speed of 16Mbps.
