对JPEG的压缩标准进行了仿真，主要过程DCT压缩，根据JPEG的量化矩阵对DCT结果进行量化，对量化结果进行Huffman编码。同时也实现了解压缩过程，即执行上述过程的逆过程。-JPEG compression standard of the simulation, the main process of DCT compression, according to the JPEG quantization matrix to quantify the results of the DCT,

复数域noiselet变换矩阵,设计了变换与反变换,有实例演示,是压缩感知技术的一个重要矩阵.-Plural the domain noiselet transformation matrix, designed to transform and inverse transform example demonstrates, the compressed sensing technology is an important matrix.

c#实现通过原矩阵求对应的逆矩阵的详细代码,c# to achieve the original matrix and the corresponding inverse matrix code

数字图片量化：图像进行高斯滤波，图像直方图均衡及其处理，图像添加噪声并且滤除，矩阵做DCT反变换，对图像做dct变换和量化-Digital image quantization: image Gauss filtering, image histogram equalization and processing, image adding noise and filtering, matrix DCT inverse transform, DCT transform and quantizati
