图像自定义选区取图源码例程程序结合易语言扩展界面支持库和操作系统界面功能支持库，实现图像自定义选区功能。(Custom image taken Figure source selection routine program combining easy language support library expansion interface and operating system interface features support library that implements a custom image selection feature.)

Canny Edge Detector to detect sharp edges in an image

说明：  c语言处理运动图像 适合初学者 对一些基本的函数介绍的很详细(c language processing motion picture)

采用的是基于弦中点的hough变换椭圆检测算法，大家可以在百度上搜这篇论文，由于不是用的标准hough变换的算法，所以运行速度还不错(Used is based on the midpoint of the chord hough transform ellipse detection algorithm, we can search on Baidu paper, because the algorithm is not used in standard hough transform, so the speed is also good)

说明：  使用matlab实现脑磁共振图像的海马体分割(Using MATLAB to segment the hippocampus of brain MR images)

对比CPU和GPU加速，pcl::cuda的使用教程，利用随机采样一致(RANSAC)去除地平面等例子。(Compare CPU and GPU acceleration, pcl::cuda tutorial, using random sampling consistency (RANSAC) to remove ground plane and other examples.)

说明：  在matlab中应用hough变换进行虹膜定位，效果不错，供大家学习！(Application of the hough transform matlab for iris location, good results for everyone to learn!)

关于计算机视觉和图像的matlab工具箱。包括相位一致性特征，空间特征检测，积分图像，非极大值抑制和滞后阈值，边链接和线段拟合，去噪，等(MATLAB and Octave Functions for Computer Vision and Image Processing。such as • Feature Detection via Phase Congruency • Spatial Feature Detection • Integral Images • Non-Maxima Suppression and Hysteresis Thresholding • Edge Linking and Line Segment Fitting • Test Grating for Edge Detection • Image Denoising • Surface Normals to Surfaces • Scalogram Calculation • Anisotropic diffusion • Grey Scale Transformation and Enhancement • Frequency Domain Transformations • Functions Supporting Projective Geometry • Feature Matching • Model Fitting and Robust Estimation • Fingerprint Enhancement • Interesting Synthetic Images • ASCII Image Generation • Rotation Transforms • Image Blending • Colourmaps and colour conversions • Image Display, Image Writing and Miscellaneous )

四种图像去噪程序，给原图像分别加上高斯噪声，椒盐噪声，乘性噪声，脉冲噪声后进行去噪，输出去噪后的图像(Four image denoising procedures, to the original image plus Gaussian noise, salt and pepper noise, multiplicative noise, impulse noise the Denoising output denoised image)

phase congruency相位一致性计算，可以用于提取图像的特征，如边缘、角点等。(calculation of phase congruency phase coherence, can be used to extract image features, such as edge, corner points.)
