r8x8dct
- 8x8的DCT算法源代码，可以移植到各种DSP芯片。
DCT_IDCT
- to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution now compare our special 8X8 functi
my_dct
- 用matlab做的基于DCT变换的图像压缩源码，先把图像分成8X8 的子块，然后做DCT变换，再量化，在恢复重建图像
DCT
- 将一幅图像先进行分成8X8块，然后对每个8X8块进行DCT变化，最后将变换后的图片进行分层，重新显示-Will an image to 8 X8 into pieces, then to every 8 X8 block DCT change, finally will transform the images after the layered, displayed again
aei(8x8)
- 用pnn或gbl进行码书设计，用aei进行码字搜索的MATLAB源码。-Pnn or carried out by gbl codebook design, aei codeword search for the MATLAB source code.
idct_
- H264中DCT和IDCT的优化算法，基于ADI平台的指令-This is the algorithm of IDCT. It is based on the separable nature of IDCT for multi-dimension. The input matrix is 8x8 real data. First, one dime-sional 8-point IDCT is calculated for each of the 8 rows
transform
- 在MATLAB中编写的用于进行一层8x8小波变换的源代码，编写时主要为了验证ise中仿真结果的正确性，所以该程序可用作参考8x8小波编写的过程-failed to translate
code-and-description-for-it
- 读入一个图片，然后调用readblock读取一个8X8块，观察图片的RGB分量-Read in a picture, and then calling readblock read a 8 X8 piece, observe picture RGB component
pmvfast
- MPEG-2/H263中用到的经典PMVFAST运动估计算法实现，支持16x16,16x8,8x8宏块大小，代码可直接运行，由C编写，方便移植-a motion estimation method of PMVFAST in MPEG-2/H.263,support 16x16,16x8,8x8 mb size
Quantization-for-DCT
- 量化离散余弦变换系数的程序实现及其效果的检测。过程中使用了8x8的分块方法。首先计算每块的离散余弦变换（DCT)；然后量化了DCT的系数； 最后进行了反离散余弦变换(iDCT). 程序中还可以设定缩放系数。-Quantify the discrete cosine transform coefficients procedure and its effect detection. The process used in the 8x8 sub-block method. First calcul
queen8
- 遗传算法解决八皇后问题。八皇后问题是一个NP问题，它的目标是把国际象棋的八个皇后摆在8X8的棋盘上，使得没有一个皇后能俘获任何别的皇后，即每一行每一列仅有一个皇后，每条对角线上至多有一个皇后。-Genetic algorithms to solve the eight queens problem. Eight queens problem is an NP problem, and its goal is to place the chess queen on the eight 8X8 ch
DCT
