Description: 图象处理及分形图象压缩是针对真彩(24位色)BMP图象进行简单处理和能够进行分形图象压缩的程序.分形图象压缩采用了固定分块和四叉树的方法,小波零树编码的方法还有问题.
图象处理部分对图片大小没有要求,分形图象压缩部分对图片大小有要求,大小应是2的次方幂(例如大小应是128*128,256*256,512*512等等),否则在菜单上看到的图象压缩里子菜单是灰的,不起作用.
-image processing and fractal image compression is against True Color (24-bit color) BMP images and can handle simple fractal image compression process. Fractal Image Compression with a fixed block and quadtree method EZW coding method is problematic. Image processing part of the picture size no, fractal image compression part of the picture size requirements, should be the size of the two-power (such as size should be 128 * 128 * 256 * 512, etc.), or else on the menu to see the image compression Lane submenu is the gray, ineffective.

This diagram 8 8 DCT, the only difference reservations DC coefficient, and the preservation of the former 4, 8 or 16 DCT coefficients (DC+ AC), and then separately IDCT transformation, the results of the comparison. 2. Using Matlab-Image Processing Toolbox to achieve the function.

Description: If you re wondering about the number 7 on the equation, the watermark is inserted every 7 pixels. Why not in every pixel? You could, but this way, you can add a second watermark (and a 3rd, and a 4th, etc.) at the same time using the pixels in between (not scripted here yet). And the insertion process is complete. The new image is saved as a bitmap format (.bmp) which saves the data as it is, without any compression whatsoever.

Description: 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.

Description: c++读取bmp图片详解。BMP（全称Bitmap）是Windows操作系统中的标准图像文件格式，可以分成两类：设备相关位图（DDB）和设备无关位图（DIB），使用非常广。它采用位映射存储格式，除了图像深度可选以外，不采用其他任何压缩，因此，BMP文件所占用的空间很大。BMP文件的图像深度可选lbit、4bit、8bit及24bit。BMP文件存储数据时，图像的扫描方式是按从左到右、从下到上的顺序。由于BMP文件格式是Windows环境中交换与图有关的数据的一种标准，因此在Windows环境中运行的图形图像软件都支持BMP图像格式。(C++ read BMP pictures detailed. BMP (full name Bitmap) is a standard image file format in the Windows operating system. It can be divided into two categories: device dependent bitmaps (DDB) and device independent bitmaps (DIB), which are very widely used. It uses bit mapped storage format, and does not use any other compression than the image depth, so the BMP file takes up a lot of space. The image depth of the BMP file is optional, Lbit, 4bit, 8bit, and 24bit. When the BMP file stores data, the image is scanned in the order from left to right, from bottom to top. Since the BMP file format is a standard for exchanging data related to graphs in the Windows environment, the graphic image software that runs in the Windows environment supports the BMP image format.)
