Description: 本文是关于小波分析在图像处理压缩方面的应用，是word格式的，文档中有详细的程序和文字分析说明，对学习的人很有帮助。
在小波方法的实际应用中，可以利用尺度方程系数构造得到小波和小波包变换算法即金字塔算法。利用张量积方法可以从一维多分辨分析直接得到二维的多分辨分析，从而方便地构造得到二维小波和小波包以及相应的分解和合成算法。在图象处理和二维数据分析研究中广泛使用的就是二维形式的小波和小波包算法。-This article is about the treatment of wavelet analysis in image compression applications, is the word format, document in detail the procedures and text analysis, and learn helpful. Wavelet method in practical applications, can use the scale factor equation has been constructed wavelet and wavelet packet transform algorithm that is, the pyramid algorithm. Use of tensor product can be from one-dimensional analysis directly from the two-dimensional multiresolution analysis, thus conveniently be constructed of two-dimensional wavelet and wavelet packet and the corresponding decomposition and synthesis algorithms. In two-dimensional image processing and data analysis study is the widely used two-dimensional form of wavelet and wavelet packet algorithm. Platform: |

Description: Images require substantial storage and transmission resources, thus image compression is advantageous to reduce these requirements. The report covers some background of wavelet analysis, data compression and how wavelets have been and can be used for image compression. This project aims at implementing wavelet transform for image compression. The wavelet transform is implemented using Matlab.As the wavelets provide a unique relation between time and scale components of the signal, this property makes wavelets suitable for image compression and also the efficient decomposition of signals prior to compression.
