这是图象处理模式识别一书的源代码，包括C++和MATLAB的程序，对于做这方面的研究人员来说，会很有帮助的。(This is an image processing pattern recognition on the source code, including C and Matlab procedures for doing this kind of research personnel, will be very helpful.)

本代码实现的功能：24位位图（BMP）的灰度化。具体实现过程：打开图像文件,找到数据区(每3个字节代表一个象素的R,G,B值),循环扫描,根据RGB的权重,计算出灰度值. 如果要得到256色灰度图,则要新建一个调色板,修改信息头和文件头.(Realize the function of the code: 24-bit bitmap (BMP) of the gray. Concrete realization of the process: Open the image file, locate the data area (3 bytes per pixel on behalf of a R, G, B values), cyclic scan, according to the weight of RGB, gray value is calculated. If you want to get 256 colors grayscale, would create a new palette, modify the header and file header information.)

基于DCT域的鲁棒水印，能抗击一定程度的压缩，剪切等攻击(Based on the DCT domain robust watermarking, can fight against a certain degree of compression, shear, such as attacks)

该文件夹包括代码及其对应的论文。其作用在于模拟人类视觉系统的生理特性--视觉注意机制，按照人眼观察外界的方式，检测视觉显著性物体和区域，并阐述了显著性区域的显著性密度和尺度之间的关系，可应用于生物视觉模拟、视觉目标检测、视觉目标跟踪、视觉智能监控，以及视觉生理学和视觉心理学等的研究中。(This document contains codes and the corresponding paper. The aim is to simulate a physiological characteristic of human visual system called visual attention mechanism. The code is used to detect salient objects or regions following the way human eye observes the world. The relation between density and scale of salient object/region is described. It has found widespread use in numerous applications such as biological vision simulation, visual object detection, visual object tracking, visual intelligent surveillance, visual physiological, and visual psychology.)

说明：  SAR图像变化检测代码，基于差异图和比值图融合的(SAR image change detection code, based on the ratio of different maps and map integration)

在桌面上显示图像，C++Builder精选编程学习源码，很好的学习资料。(Image display on the desktop, C++Builder select learning programming source code, very good learning materials.)

MATLAB程序；图像的小波系数提取，然后进行奇异值分解，得到图像的特征系数。(MATLAB program wavelet coefficients of the image extraction, and singular value decomposition, image feature coefficients.)

off文件读取绘图函数，能读取顶点坐标和拓扑关系，并以此绘制三维模型图像，使用可以直接调用，需要注意参数的类型，只能读要取off(Off file to read the drawing function, can read the vertex coordinates and topological relations, and in order to draw the three-dimensional model images, the use of direct calls, you need to pay attention to the type of parameters, can only read to take off )
