各种特征提取主成分分析法pca

O(n*logn)时间内的求逆序的算法控制台程序，算法实现效率较高。可迅速求出随即生成的数字的逆序数(O (n* logn) time algorithm for reverse console process, algorithm more efficient. Can be generated quickly obtained immediately reverse digit number)

程序可实现dwg文件注记的批量替换, 可根据需要进行扩展。(Dwg file program allows batch replacement Note)

说明：  VC做的图像直方图均衡化小程序，有助于学习图像处理基本知识(VC image histogram equalization do applet can help to learn basic knowledge of image processing)

说明：  由于只是利用图像的灰度信息, SIFT 算法不能很好地区分形状相似但颜色不同的物体。针对这一问题, 提出了一种基于彩 色的SIFT 特征点提取算法, 并着重分析了多种彩色模型对算法性能的影响。这种算法也是在图像的灰度尺度空间上检测特征点, 但其特征向量由各描述子子区域的彩色模型分量的均值组成并在原始的彩色图像上进行计算。(SIFT)

旋转的地球，有光照，贴图，放大缩小…… 左击旋转，右击放大缩小(whirl of the Earth)

本书可作为信息处理、计算机、机器人、人工智能、遥感图像处理、认知神经科学等有关专业的高年级学生或研究生的教学用书，也可供相关领域的研究工作者参考。(This book can be used as information processing, computer, robot, remote sensing image processing, artificial intelligence, cognitive neuroscience and related professional senior student or graduate student s teaching resources, also can be used for reference in the related areas of research workers.)

图像处理中C#畸变校正程序，针对鱼眼图像的径向畸变校正，利用空间直线在校正图像中仍然为直线的基本原理，且直线在除法模型下为圆弧，从而可以通过检测圆弧对鱼眼图像进行畸变校正。(Image processing program C# distortion correction for radial fisheye image distortion correction, the use of space in a straight line in the corrected image as the basic principle is still straight, and a straight line at the division model is a circular arc, so that the arc can be detected by fish eye image distortion correction.)

说明：  颗粒粗化源码，将马赛克现象认为的作用于一副图像，称之为颗粒粗化。可以用来建立图像切换效果(source of coarse particles, that the phenomenon will mosaics in the role of an image, known as particle coarsening. Images can be used for switching effects)

多层mie散射程序,可以模拟多层粒子的散射情况。(multi-layer mie scatter )

鱼眼图像校正并将校正后的图像转换成鸟瞰图，即俯视图，纯C代码，没有调用其它库(fish eye image correction,then change it to bird s eye view)
