Description: Simulations over AWGN and Rayleigh channels, at various signal-to-noise ratios, verify the excellent performance of this novel APEL-turbo scheme. Performance comparisons were carried out between turbo coded APEL, JPEG, and BMP image files.
To provide a fair comparison between the APEL and JPEG images, compression level had to be the same. This resulted in the data reduction for both APEL and JPEG to be around 5 to 1.
In the assessment of bit errors within a received image file, a quantitative pixel error rate offers a fairer comparison. Therefore, it is appropriate to represent the error performance in a ratio called “Pixel Error Rate (PER)”, which is a measure of the degree of image degradation.
Through the analysis of the ith received pixel’s variance from its transmitted value, a measure of visual disturbance, Δi, can be quantified as in (1), where ti and ri represent the transmitted and received pixel colours respectively, for an n colour image.

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

Description: 可以方便的制作手机壁纸:
1.支持bmp,jpg,gif(gif只支持第一帧),png格式
2.输出格式为jpg,因为我感觉小尺寸的图片文件在图片失真不严重的情况下jpg格式比其他格式友更好的压缩比
3.支持图片翻转,平滑等特效
4.操作简单,方便易用.-You can easily create mobile phone wallpaper: 1. Supports bmp, jpg, gif (gif only supports the first frame), png formats 2. Output format jpg, because I felt that the small size of the picture files in the image distortion is not severe cases, jpg format, a better friend than any other format, compression ratio 3. to support image flip, smooth and other effects 4. simple and easy to use.

Description: 本程序要构造的位图为24位bmp格式，通过直接为结构体BITMAPFILEHEADER和BITMAPINFOHEADER赋值的方式生成。本程序演示的功能比较片面，但也比较实用。如果面对大量的数据，特别是二维的数组，可以尝试将它们写成图像，这样有助于发现规律。
压缩包中还有几个关于结构体说明的文档，可帮助理解。-This procedure to construct the bit picture shows the 24-bit bmp format, through direct BITMAPFILEHEADER for the structure and the way BITMAPINFOHEADER assignment is generated. This program demonstrates the function relatively one-sided, but also more practical. When faced with large amounts of data, especially in two-dimensional array, you can try to formulate them in the image, so help to identify the law. Compression package, several documents on the structure description can help to understand.

Description: 压缩包的内容包括：1.有关JPEG和DPCM算法的文章；2.实现其算法的压缩程序3.有关图像压缩方面的资料。读者请注意：
<1>这里讨论的是灰度图像的压缩不涉及彩色图像。
<2>实现压缩时，输入的图像数据采用一种自定义的格式（com 格式），前四个字节记录图像的宽度和高度，之后就是逐
行的图像数据，图像的开头和结尾没有任何标记。这种格式的图像数据是从BMP图像中得到的。
<3>这里没有JPEG算法的解压程序，压缩后的数据存成标准的JPEG文件格式，任何视图软件都可以打开。DPCM方法中的解
压缩程序将数据仍然存成com格式，可以将其转成PGM格式观看，压缩包中由com转为PGM格式的程序。
<4>所有的C程序均是在Linux（Rethat7.3)下完成。-Compressed package includes: 1. The JPEG and DPCM algorithm article 2. To achieve its compression algorithm procedure 3. The image compression information. Readers please note:
<1> discussed here is the gray image compression does not involve color images.
<2> to achieve compression, the input image data using a custom format (com format), record the first four bytes of the image width and height, and then is gradually
Line of image data, image mark the beginning and no end. This format of image data is obtained from the BMP image.
<3> There are no procedures for JPEG decompression algorithm, compressed data stored as a standard JPEG file format, you can open in any view. DPCM method of solution
Compressed program data is still stored as com format, you can watch it turn into a PGM format, compressed in the com format to PGM program.
<4> All the C programs are in Linux (Rethat7.3) to complete.
