| Abstract: | A pyramid decomposition and reconstruction algorithm can be derived based on the definition and characteristic of haar wavelet.In this paper,we present a two-dimensional multi-scale pyramid decomposition and reconstruction algorithm based on Matlab.Reciprocal experiments show that the algorithm not only could perform two-dimensional multi-scale pyramid decomposition and reconstruction,butalso could reduce the computational complexity effectively and improve computational precision.Furthermore,we show that the algorithm is able to deal with image denoise and compression. |
