Description: 实现jpeg图像解码功能。
代码设计思路：1, Reconstruct the Huffman/RLE stream to a sequence
2, Arrange the sequence to a matrix using the zigzag scanning backwards
3, Multiply the matrix by quantization table
4, Perform inverse DCT
5, Shift the values by +128
6, Transform back to RGB color space

Description: This project features a complete JPEG Hardware Compressor (standard Baseline DCT, JFIF header) with 2:1:1 subsampling, able to compress at a rate of up to 24 images per second (on XC2V1000-4 @ 40 MHz with resolution 352x288).
Image resolution is not limited. It takes an RGB input (row-wise) and outputs to a memory the compressed JPEG image. Its quality is comparable to software solutions.

Description: RGB,YCbCr,HSV,HSL,CIE等颜色空间转换
这个Matlab程序用于颜色空间的转换。可以在RGB, YPbPr, YCbCr, YUV, YIQ, YDbDr, JPEG-YCbCr, HSV, HSL, XYZ, CIE Lab (CIELAB), CIE Luv (CIELUV), and CIE Lch (CIELCH)等颜色空间中任意转换。-B = colorspace( dest<-src , A) converts image A from color space src to color space dest .
Example:
B = colorspace( HSV<-RGB ,A) Convert image A from RGB to HSV
C = colorspace( YCbCr<-HSV ,B) Convert HSV to YCbCr
D = colorspace( RGB<-YCbCr ,C) Convert YCbCr back to RGB

Description: 实现将原始位图数据编码成为JPEG文件，发送到串口。
现在程序还是热呼呼的，因为刚才才从VC程序移植到STM32成功，实现正常压缩。
稍作修改，可以接摄像头，做成jpeg串口摄像头。
硬件只需要：stm32f103ZET6,串口usart1。
图像数据从usart1输出，波特率115200.可以用串口软件接收数据，保存为.jpg后缀名，即可在电脑上打开该图片文件。
我用的串口软件是AccessPort。
编码生成的图片大小为320x240.
原始图片以RGB数组的形式放在程序里面了，大小为240x16.因为320x240的bmp图片会到200多K，所以只截取了一部分-To achieve the original bitmap data encoded as JPEG files, sent to the serial port. The proceeding is still warm, because as mentioned before porting from VC to the STM32 success, to achieve a normal compression. Some modifications, you can access the camera, made jpeg serial camera. Hardware only: stm32f103ZET6, serial usart1. The image data from usart1 output, baud rate 115200. Can use the software to receive serial data, save it as. Jpg suffix name, the computer can open the picture file. I use the serial port software is AccessPort. Encoding generated image size is 320x240. The original image to RGB in the form of an array of programs on the inside, and the size of 240x16. Because it will be 320x240 in bmp images to more than 200 K, so only a portion of intercepted
