- 分形图像压缩原始算法,包括压缩和解压。 根据Jacin的分块压缩原理-fractal image compression original algorithm, including compression and decompression. According to the sub-block Jacin compression Principle
DCT
- 将图象分块(8*8),作DCT变换,并作IDCT:DCT是一种可分离图象变换,用来图象压缩编码,IDCT用来解压缩。-The image sub-block (8* 8) for the DCT transform, and to make IDCT: DCT is a separable image transformations, is used to image compression coding, IDCT is used to decompress.

frequencycoefficients
- 将图像分为nxn的分块,之后将各分块三个颜色通道的直方图平均化,最后进行离散余弦变化,分别提取各通道低频系数-The image into nxn sub-block after block of all three color channels of the histogram equalization, and finally the discrete cosine change, were extracted from the low frequency coefficients of e

- 实现9/7小波正反变换 注1: 采用标准正交方法,对行列采用不同矩阵(和matlab里不同) 注2: 为了保证正交,所有边界处理,全部采用循环处理 注3: 正交性验证,将单位阵带入函数,输出仍是单位阵(matlab不具有此性质) 注4: 此程序是矩阵实现,所以图像水平分量和垂直分量估计被交换位置 注5: 此程序实现的是类小波(wavelet-like)变换,是介于小波包变换与小波变换之间的变换 注6: 此程序每层变换相对原图像矩阵,产生的矩阵都是正交阵,这和小
