目标物与摄像机距离已知的情况下，计算白天大气能见度距离。(The distance between the object and the camera is known to calculate the visibility distance in daytime.)

Tracking based on background subtraction

说明：  基于matlab车牌识别系统，主要涉及图像预处理、车牌定位、倾斜角矫正、字符切割、字符识别五个模块(License plate recognition system based on MATLAB.It mainly involves five modules: image preprocessing, license plate location, tilt angle correction, character cutting and character recognition)

计算机图形学中小例子，MFC下实现Sutherland_Cohen直线段裁剪算法(Computer graphics small example)

给予matlab的JPEG压缩程序，包含原始压缩图片，程序对灰度bmp图片进行JEPG编码，压缩成以0101形式的编码。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb，它利用人的视觉对色度不敏感的特点，减少一部分色度数据，以达到压缩。 JPEG采取多种编码方式，包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码，有很高的压缩比。在编码前，先对数据进行分块，离散余弦变换（DCT）及量化，保留能量大的低频信号，丢弃高频信号以达到压缩。(Given to the JPEG compression matlab program, contains the original compressed image, the program of the grayscale bmp picture JEPG encoded, compressed into a 0101 form of encoding. RBG color coded JPEG image into a first luminance Y and chrominance Cr, Cb, which uses the human visual characteristics is not sensitive to the color, reduce the number of color data to achieve compression. Take a variety of JPEG encoding, includes length coding (Run Length Coding) and Huffman (Huffman) coding, a high compression ratio. In the code before the data block, discrete cosine transform (DCT) and quantization, to retain a large low-frequency signal energy, discarding high-frequency signals in order to achieve compression.)
