用EM算法进行图像的分割，matlab源代码。(EM algorithm using image segmentation, matlab source code.)

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.)

图像超分辨率是指从一序列低分辨率观测图像中重建高分辨率图像。图像超分辨率充分利用了各帧图像 间相似而又不同的信息。(Compared with the model derived from Kolmogorov spectrum, the new model introduces more complete transcendent constraints and is more similar to the physical characteristics of atmospheric turbulence.)

说明：  图像融合指标，综合熵、空间频率、互信息等等，一共7种。在图像处理后的质量评价方面很有用(Fusion index, comprehensive entropy, spatial frequency, mutual information, etc., a total of 7 species. In the image processing is useful for quality assessment)

利用halcon mfc写了一个模板匹配demo，可以基于形状匹配，形状缩放匹配，灰度匹配对图像进行匹配

在matlab环境下对图像进行处理，运用霍夫变换方法得到图像分割的阈值，并进行圆形的检测(In the matlab environment for image processing, using Hough transform method for image segmentation threshold and for the detection of circular)

为了研究植物的生长规律，应用数字摄影图像处理法对山楂叶面积进行无损测量，该方法采用数码相机在田间获取山楂叶子的数字图像，对所拍图像进行背景去除、二值化及中值滤波处理，然后利用Matlab软件编程．快速计算出叶子的面积。把这一面积同常用的叶纸称重法所测面积进行比较．结果基本相同，由此可见，数字摄影图像法测量叶面积，具有简单、准确、方便快捷的特点．这对数字农业的植物信息快速采集和利用具有重要的意义。 ( In order to study the growth pattern of plants, the application of digital photography and image processing method for nondestructive measurement of hawthorn leaf area, this method using a digital camera to obtain digital images of hawthorn leaves in the field, on the film image background removal, binarization and medianfiltered, and then using the Matlab software programming. Quickly calculate the area of the leaves. This area with the common leaf paper weighing measured by the area to compare. The results are basically the same, shows, digital photographic images method to measure leaf area, with a simple, accurate, and convenient features. This rapid acquisition and use of digital agricultural plant is of great significance. In order to study the growth pattern of plants, the application of digital photography and image processing method for nondestructive measurement of hawthorn leaf area, this method using a digital camera to obtain digital images of )

基于Hough变换的虹膜自动分割的matlab代码(Automatically based on Hough transform in iris segmentation matlab code)

大名鼎鼎的GN：genesis的相关开发资料 做液晶电视，以及OSD字符叠加以及高级视频控制的朋友可以来看看，这些资料可是要和GN签订保密协议才会给的！(Famous GN: genesis of the relevant information to do the development of LCD TV, as well as the OSD characters, as well as advanced video overlay control friends can look at it, but such information should be entered into confidentiality agreements and GN will give!)

分割图像中的有效数字,抗噪声，抗直线，斜线，粘连字符分割，旋转角度最大支持5度(Effective image segmentation figures, anti-noise, anti-straight, slash, adhesion character segmentation, rotation angle of 5 degrees maximum support)
