[2D Graphic] FasteffectiveDCT

Description: DCT变换是数字图像处理中重要的变换，很多重要的图像算法、图像应用都是基于DCT变换的，如JPEG图像编码方式。对于大尺寸的二维数值矩阵，倘若采用普通的DCT变换来进行，其所花费的时间将是让人难以忍受甚至无法达到实用。而要克服这一难点，DCT变换的快速算法无非是非常吸引人的-DCT digital image processing is an important transformation, many important images algorithm, imaging applications are based on the DCT, such as JPEG image encoding. For large-size two-dimensional numerical matrix, if only the ordinary for DCT, they spent the time people will be unable to reach intolerable even practical. To overcome this difficulty, DCT fast algorithm is nothing more than a very attractive

[Special Effects] jpeg

Description: 论文主要介绍了JPEG的编码和解码过程。该程序的编码部分能把一张BMP格式的图象进行JEPG编码，压缩成以二进制形式保存的文件；通过相应的解码程序又可以把图象解压缩出来。在图象传送过程中，我们经常采用JPEG格式对静态图象进行编码。JPEG基本系统是一种有损编码，无法完全恢复出原图象，信息有一定的丢失，称为有损压缩。尽管我们希望能够无损压缩，但是通常有损压缩的压缩比(即原图象占的字节数与压缩后图象占的字节数之比，压缩比越大，说明压缩效率越高)比无损压缩的高。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb，它利用人的视觉对色度不敏感的特点，减少一部分色度数据，以达到压缩。 JPEG采取多种编码方式，包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码，有很高的压缩比。在编码前，先对数据进行分块，离散余弦变换（DCT）及量化，保留能量大的低频信号，丢弃高频信号以达到压缩。解码时，进行熵解码，反量化，反离散余弦变换（IDCT）。

[VHDL-FPGA-Verilog] jpeg.tar

Description: This project features a complete JPEG Hardware Compressor (standard Baseline DCT, JFIF header) with 2:1:1 subsampling, able to compress at a rate of up to 24 images per second (on XC2V1000-4 @ 40 MHz with resolution 352x288). Image resolution is not limited. It takes an RGB input (row-wise) and outputs to a memory the compressed JPEG image. Its quality is comparable to software solutions.
