Description: 分形用于图像压缩编码,分形编码非常费时，大部分时间浪费在给每个range块寻找合适的domain块，但如果减少搜索domain块的范围，编码速度将有很大提高。所以编码时用快限制分形编码,把图像分成4小块，每块中的range块只在这块中寻找domain块。-for fractal image compression coding, fractal coding is very time-consuming, most of the time wasted in each range block to find a suitable domain block, But if the search domain blocks to reduce the scope of coding speed will be greatly improved. So fast coding using fractal coding restrictions, the image is divided into four small pieces. every piece of the range block only find in this domain block.

Description: 本文结合DCT变换的特性，利用分形的Peano一hilbert扫描曲线，对基于DCT变换的图像编码方法进行了研究，并提出了改进方法。主要工作分为两个部分: 一是在分块DCT基础上的改进。对分块后生成的各图像块矩阵，不直接作二维DCT变换，而是先进行扫描，使之重排成一维向量，再进行一维DCT变换，这样可以减少运算量。 其次是对层次余弦变换编码部分的改进。使用层次DCT变换与零树编码相结合的方法，并在扫描编码过程中，按Peano一hilbert扫描顺序进行编码。这样不仅可以减少“块效应”，而且可以加快编码速度。-this paper the characteristics of DCT, using fractal Peano a Hilbert scanning curve, the DCT-based image coding method for the study and improvement of methods. The work is divided into two main parts : First, the DCT block on the basis of improvements. Right after block production of the image block matrix, not for direct two-dimensional DCT, but first scan, so they line up in a heavy-dimensional vector and then a peacekeeping DCT, thus reducing the amount of computation. Secondly, the level of cosine transform coding some of the improvements. The use level of DCT and zero tree coding combination of methods, coding and scanning process, according to a Hilbert Peano code scanning sequence. This will not only reduce the "blocking effect" but we can speed up the coding speed.

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.
