gabor是将图像转换成gabor特征，增强系统鲁棒性，使其不易受外界条件影响；norm是将图像的灰度值统一归一到一个范围内，便于同等使用图像。(gabor gabor is a feature to convert images to enhance the system robustness to make it less susceptible to external conditions affect norm is a uniform gray value image normalized 1-1 range, the same easy to use images.)

基于四叉树分解并且使用区域分离和合并的图像分割(based quadtree decomposition and the use of regional separation and integration of image segmentation)

将原图像用bior四层分解，之后弱化低频分量，重构原图，以得到细节。(use wavelet function(bior) to enhance the detail of the image,then reconstuct)

各种数字水印的matlab源代码，DCT，小波变换等。(Various digital watermarking matlab source code, DCT, wavelet transform.)

ofdm系统仿真用QAM调制的，有信号传输后的频谱图(ofdm simulation using QAM modulation)

在matlab，传统的边缘检测直接调用edge函数，但是得到的边缘信息较稀薄，可以通过将sobel,roberts,prewitt三种算子的边缘检测叠加起来，并且对于连续的边缘部分拓宽，使得边缘更连贯清晰(In matlab, traditional edge detection edge direct call function, but thinner than the edge information can be obtained by sobel, roberts, prewitt three edge detection operator stack up, and for widening the continuous edge portion, so that the edge is more consistent clear)
