图像压缩

In this paper we proposed an improved method which changes the definition of the 4-neighborhood model. we call it side neighborhood minimum absolute weight prediction tree technique. lt can simplify the algorithm and improve the results of lossless compression.

本文对预测树方法进行改进，提出一种侧邻域最小绝对权值预测树方法，通过改变预测树的四邻域定义，使构造预测树的算法简化，并且，实验结果表明，对不同类型的多光谱遥感图像，SNMAW的压缩效果与MAW的压缩效果相近或有所改善。

Experimental results show that the method is able to compress video rapidly and effectively, a...

In this article, firstly embedded system development actuality and trend are introduced, a project of palmtop type image display system based on embedded network server is proposed. Secondly based on TI company special DSP processor TMS320DSC21, a brief introduction of components of system hardware is done. Following this the theory and reality analysis of JPEG image decompression is done, it is one of the most important technique in digital image process.

本文首先介绍了嵌入式系统的发展现状和趋势，并提出了一种基于嵌入式网络服务器的手持图像显示系统方案：接着基于TI公司的专用DSP处理器TMS320DSC21，简要介绍了系统硬件平台的组成；然后，对该方案中数字图像处理的关键技术之一——JPEG图像解压缩进行了原理上和具体实现上的分析。

Two image quality evaluation of the function. Including psnr PSNR, it is mean-square error nmse other. Images can be used for de-noising and compression of image quality evaluation.
