[Special Effects] fwt2d_demo DL : 0: 小波变换源码，国外VC开发的，效果比较好 I ve been involved with wavelet-analysis since my Ph.D studies and over the years developed various wavelet-transforms C++ libraries. This one concerns 2D implementation of the Fast wavelet transform (FWT). The 2D FWT is used in image processing tasks like image compression, denoising and fast scaling. I intended to design the implementation of the 2D FWT with custom filter support and simple in usage. I ve equipped it with known filter families: Daubechies, Coiflets and Biorthogonal wavelets. The wavelets used in compression tasks are Bior53 and Bior97. With Daub1 filter you can achieve fast dyadic image scaling algorithm. You may also experiment with other filters for compression and denoising and compare the results, you may also add your custom wavelets. The nice feature of this library is that reconstruction FWT filters are rearranged the way that you perform just convolution operations on the spectrum, which is very important if you d like MMX -err

[Special Effects] UPLOAD_LY1 DL : 0: 图像处理于MATLAB上的应用，能很好的处理一些熵，概率等问题-(a)Find the entropy of this source using Matlab (b)Design the Huffman code for this source using Matlab. (c) Randomly generate a source sequence of length 500 symbols drawing the symbols from the true source distribution. Encode the generated sequence using the Huffman code developed in (b). Decode the sequence and compare the decoded and original sequences. (d)Find the efficiency of the code in this case.

[Special Effects] UPLOAD_LY4 DL : 0: 通过MATLAB的程序解决相应图上处理中熵值和概率的问题-Adaptive Arithmetic coding. A source generates symbols from alphabet {A, B, C, D}. Probabilities of occurrence of the symbols are initially estimated as: Pr(A)=Pr(B)=0.25, Pr(C)= 0.2, and Pr(D)=0.3. After 100 generated symbols, the statistics changes to Pr(A)= 0.1, Pr(B)=0.3, Pr(C)= 0.4, and Pr(D)=0.2. After 300 symbols, statistics is: Pr(A)=0.6, Pr(B)=0.05 Pr(C)=0.1, and Pr(D)=0.25. Randomly generate a source sequence of length 500 symbols drawing the symbols from the true source distributions. That is, for the first 100 symbols, next 300 symbols, and last 100 symbols use the three distributions above, respectively. Encode this sequence using adaptive arithmetic coding that adaptively changes frequency of the source symbol occurrence every 100 symbols. Decode the sequence and compare the decoded and original sequences. Find the efficiency of the code.
