fft

说明：  基于matlab实现对将视频以帧为单位截取为图片，用背景差分法进行比对，实现对运动目标的检测。含代码，运算结果。(Based on MATLAB, the video is captured as a picture by frame, and compared with the background difference method to achieve the detection of moving objects. Including code and operation result.)

遥感图像除云软件，原理是图像同时期替换掉有云区域，使用IDL语言编写(remove cloud from remote sensing image)

颜色特征提取，为matlab 源文件，是底层图像处理的基本特征之一，是本人在做硕士论文时收集修改的代码(Color Feature Extraction for the matlab source file, the underlying image processing are one of the essential features)

winform 垂直交错效果显示图像 例子

用霍夫曼编码，零树小波算法解码，图像处理过程(huffman encode ，ezw decode)

自己曾经做的一个项目，基于几何特征的模式识别。可以有效的识别等边三角形，矩形，六角形 和圆形。 基于c++和OpenCV 编写的程序。是学习OpenCV的好代码。 图像处理&模式识别。(Marksdetection for equilateral triangles,rectangle, regular hexagon, special orthogonal polygons and circles Based on C++ and OpenCV good source code for image processing and mark detection)

利用图像的不变矩以及模式识别的内容，构造三维飞机图像的矩特征，然后再利用D-S证据理论的改进方法 吸收法对图像进行融合 对飞机的型号进行匹配(Moment invariant of image and pattern recognition of the content, structure features three-dimensional plane images of the moment, and then use the improved DS evidence theory method of absorption of the fusion images to match the type of aircraft)

SIFT特征是图像的局部特征，其对旋转、尺度缩放、亮度变化保持不变性，对视角变化、仿射变换、噪声也保持一定程度的稳定性，亲身检测可用(SIFT feature is a local feature of image. It keeps invariant to rotation, scaling, brightness change, and also keeps a certain degree of stability to view angle change, affine transformation and noise.)

RGB 颜色选择器，可以自由选择颜色，也可以用吸管吸取屏幕颜色色值，便于程序员们开发(RGB color picker, you can choose colors freely, or you can suck the color value of the screen with a straw, which is easy for programmers to develop)

亚像素边缘检测，基于zernike 灰度矩，实现精度可达0.05个pixel(sub-pixel edge detect)
