ABSTRACT Fractal image coding, which is also called attractor image coding, is a emergent method of image compression during the last decad...

分形图像编码方法是近十年来诞生并发展起来的一种新型图像压缩方法，它将图像编码为一组收缩映射，由这组收缩映射的不动点近似待编码对象。

We excogitate the gabor filter based - on sub - block texture analyse to extract the feature of iris normalized image and encode them . then , we use hamming distance to match two iris codes . in order to reduce the rotation of iris , we work out a new method

研究出基于子块纹理分析的gabor滤波器方法来对虹膜归一化图像进行特征提取和编码；在虹膜编码匹配中，本论文采用hamming距离来进行编码之间的匹配。

So, these standards still couldn't satiate the demands of very low bit-rate applications (under 20kb/s). As to still image coding, even though the performance of wavelet image coding algorithms excel first generation image compression standard JPEG, but they will produce boring mosquito noise at low bit-rates, which are mainly located around image edges.

而在静态图像编码方面，虽然小波图像算法的编码性能远远超过第一代图像压缩标准JPEG，但它在低位率条件下也会出现蚊式噪音，主要集中在图像边缘附近，而且对于包含丰富纹理的自然图像，其编码效率也会急剧下降。

This algorithm involves multi-frame motion compensationk,rate-distortion optimizing strategy with Lagrangian cost function and context-based adaptive arithmetic coding.

根据系统的终点和初始状态，提出了泛横向对称编码和泛纵向对称编码理论，为进一步拓展对称编码理论的应用空间提供了理论基础。

The coding method includes the steps of representing respective digital data by digits of a predetermined same number, and coding the digital data represented by digits of the same number by a predetermined coding method from the uppermost significant digit sequence to the least significant digit sequence.

编码方法包括以下步骤：用相同的预定位数表示有关数字数据，以及使用预定编码方法自最高有效位序列至最低有效位序列将由相同位数表示的数字数据编码。

In this paper,a new coding scheme is proposed,which is named as prefix division coding scheme.

在对现有编码机制进行综述的前提下，提出一种新的XML文档编码机制——前缀整除编码机制。

Throughcalculation, we find that there are remarkable differences between coding and non-coding sequences, and vector from random sequences is closely related to that fromthe coding sequences.

通过计算，我们发现，编码区和非编码区所对应的4维向量有很大不同，并且随机序列与编码区对应的向量较为接近。

The algorithm deals with the points of the vertex chain code around a region,matches points in the same scan lines and uses scan lines to fill the region,and then the binary image will be reconstructed.

该算法对表示二值图像区域的顶点链编码点进行记录处理，配对被记录的顶点链编码点，然后运用水平扫描线来填充图像区域，从而将原图像根据顶点链编码完全恢复出来。

Thedecoder the proposal algorithms required is compatible with JPEG2000 standard.TheDIRC rearranges truncation point for every codeblock in each layer. It assigns higherbitrate to ROI and lower bitrate to non-ROI and combines them to codestream. TheDWARC can achiev the accurate bitrate control in each layer.

本文第三章探讨了感兴趣区域编码问题，提出了二种动态、码块优先的ROI编码算法DIRC、DWARC，二者均支持多个感兴趣区域有各自独立的优先级并且优先级可以在编码过程中动态改变，其生成码流与标准完全兼容。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
