DCT_JPEG
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.)

PicMatch
本程序实现了对影像特征点自动提取,利用Morevac、Forstner、Harris3个经典算子。在此基础上利用相关系数法实现影像自动匹配,并且引入最小二乘平差,使匹配点精度有所提高。
在搜索点过程中,利用了核线影像特性,对二维影像搜索使用了爬山法启发式搜索。对大数据量影像采用影像金字塔结构处理。
1、使用GDAL库读取影片,支持TIFF、PNG、JPEG、JPG、BMP、GIF、IMG格式读取。使用GDI绘图。
2、防止大数据量绘图视图闪烁,图片显示采用双缓存技术。
3、保存视图数据为图片文件,支持TIFF、PNG、JPEG、JPG、BMP、GIF格式保存。
4、TreeCtrl控件、ListCtrl控件的基本操作。
5、MFC单文档程序视图通讯、更换视图、视图分割。(This program of image features automatic extraction point, use Morevac, Forstner, Harris3 a classic operator. Based on the correlation coefficient method using the image matching, realization and introducing least squares adjustment, the matching point to improve precision.
In the search process, the use of the image characteristics of nuclear line, 2d image search using the heuristic method of climbing. For large quantity of data using image processing image pyramid structure.
1, using film, read GDAL repository support JPEG, TIFF, PNG, GIF, BMP, JPG, read IMG format. Use GDI drawing.
2 and prevent large amount of data, drawing view pictures showed adopt double caching techniques.
3, save for the image file, views data support JPEG, TIFF, JPG, PNG, GIF, BMP format.
4 and TreeCtrl controls, the basic operation ListCtrl controls.
5 and MFC single document procedure view communication, replace view, view.)
