With the theory of wavelet transform and reversible integer - to - integer wavelet transforms based on shifting frame used in image / video compression field introduced, a new real - time implement of speck algorithm using dsp chip is provided. then the technology of motion estimation and motion compensation is discussed and an adaptive technique for the wavelet video codec to reduce the " block artifact " is presented. and the implement of the wavelet video compression system using adv611 chip is discussed next with the performance emulation result
在系統討論了小波理論在圖像視頻壓縮編碼領域的應用后，結合dsp技術提出一種基於dsp應用的實時低存儲需求的改進speck圖像編碼器；隨后探討基於小波變換的實時視頻編碼器的實現，在論述運動估計與補償技術的基礎上，針對應用空域運動估計補償技術的低比特率小波視頻編碼器提出一種自適應消除塊效應的技術；並討論了基於adv611晶元的視頻壓縮系統的壓縮性能；最後提出一種基於dsp平臺具有極低時延的小波視頻混合編碼方案，對該方案的壓縮性能進行了討論並給出初步的硬體實現方案。 -
Secondly klt and reversible integer - to - integer wavelet transform for image compression are discussed, and a method of nearlossless compression of multispectral images is given, which combines klt and integer wavelet transform together. the spatial redundancy in the images is removed by klt and the inter - band redundancy is removed by the integer - to - integer wavelet transform
接著詳細研究了k - l變換原理和整型小波的構造方法，編程實現了結合k - l變換和整數小波變換的多光譜圖像壓縮演算法，該演算法將k - l變換用於去除多光譜遙感圖像的譜間冗餘，在譜內則使用整型小波方法去除空間冗餘。
