基于图像处理的相机自动调焦系统

A set of matlab funcitons used in the field of digital image processing (pattern recognition).

（计算机图形学）用Bresenham实现画圆的算法，用MidPoint实现画椭圆的算法-(Computer graphics) to realize drawcircle Bresenham

实现图像数据的JPEG-LS标准的压缩，可以实现无损压缩也可以进行有损压缩-Realize image data standard JPEG-LS compression, lossless compression can be lossy compression can also be carried out

视频分析中目标标定算法，包含很多经典的算法，非常实用，欢迎下载-ObjMark_For_TrackingAggregateTrajectory Hidden Markov Model algorithm package （HMM），Contains a lot of classical algorithms, very useful, please download

可以颜色空间转换和各种颜色变换，里面有图像可供测试使用-Can be color space conversion and a variety of colors transform, there are images available for test use

有关数学计算――点积 适合于计算图形，尤其多边形计算方面，英文网页-the mathematical calculations-- for the plot point in the calculation of graphics, particularly polygon calculations, the English website

图形处理功能，有滤波功能，边缘提取等各个方面，值得一看-Graphics processing capabilities, has filtering, edge detection and other aspects, see

程序内包含了大量的图像处理子程序，像离散傅里叶变换，离散余弦变换还有图像编码，图像分割多个方面的内容，值得借鉴。-Program contains a large number of image processing routines, such as discrete Fourier transform, discrete cosine transform still image coding, image segmentation various aspects, it is worth learning.

图像分割与特征提取 C开发 The picture division and the characteristic withdraw--C development -Image Segmentation and Feature Extraction C Development The picture division and the characteristic withdraw- C development

本文提出了一种基于区域分割的分段线性变换方法，结合灰度直方图提供的有关灰度分布的统计信息 和图像提供的空间位置信息，利用各灰度区间把图像分割成不同的区域，检验要增强的目标是否落在某 灰度区间对应的图像区域内，从而加快了调整灰度区间的过程，提高了算法的执行效率。-dddddddddddddddddddddddddddddd
