Description: BMP与JPG文件格式转变的源代码
一个把BMP压缩成JPG的源代码。 大小：16.4K
附：
1. 编译说明
1) 在VC IDE 选择setting->link> 加jpeg.lib
2) 编译程序
2. 原理 程序首先读BITMAP 文件的各像素点的RGB值, library 做压缩 RGB 缓冲区成JPEG文件或缓冲区。-BMP and JPG file format changes in the source code BMP put a JPG compressed into the source code. Size : 16.4K : Attachment 1. Compiler Note 1) VC IDE choice setting-gt; Linkgt; Plus jpeg.lib 2) compiler 2. Principle procedures BITMAP first reading of the document point pixel RGB value, library so compressed RGB JPEG files into the buffer zone or the buffer zone. Platform: |

Description: Video Reading Code for Matlab. This some C++ and mex code written as a Matlab wrapper around the ffmpeg video reading libraries. It should compile under Windows and Linux. (The Windows compilation requires mingw gcc. Extact installation instructions are included in a Readme.txt in the downloaded files.) Thus from within Matlab one can grab the RGB data from specified frames from a named video file. The code should be able to read all video clips that are readable by ffmpeg. Note that we are making this code freely available, however no promises are made as to its reliability or that the code will be supported. However, if bugs are found and easy to fix, then new releases will probably be made available. It should be noted also that ffmpeg is lgpl. -Video Reading Code for Matlab.

Description: 用纯C写的读RGB文件格式的代码，返回文件头和数据头，这样再读写数据就容易多了。支持8位，24位RGB图。Linux系统里面RGB图片数据格式存储格式为RGB，从上往下填充；而Windows系统里，RGB图片存储格式为BGR，从文件的最后一行开始填充，所以读取RGB图时得注意。-Written in C with pure RGB file format reading the code, return the first file header and data, so re-read and write data much easier. Support for 8, 24-bit RGB Fig. Linux system inside the RGB image data format storage format for the RGB, from top-down filling and Windows systems, RGB image storage format is BGR, from the documents began to fill the last line, so readers have to pay attention to RGB map.
