Wavelets have widely been used in many signal and image processing applications. In this paper, a new serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is done using a tree of carry save adders to ensure the high speed processing required for many applications. The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis reveals that the proposed architecture, implemented using current VLSI technologies, can process a video stream in real time.

在網上找到了臺灣java專家林信良的著作 《Spring 技術手冊》的電子書和大家分享下~~~只是缺了AOP的介紹,不過已經很全面了 臺灣技術書籍的特點:通俗易懂,深入淺出,結合實例~~~不過,全是繁體字的哦。。。。 另外,《Spring 技術手冊》左邊的index tree 是亂碼!但這里有個鏈接是在線文檔,目錄可以對應那上邊的~~:http://www.javaworld.com.tw/conflue.../opensrc/Spring

Electromagnetic scattering from the trees above a tilted rough ground plane generated by the stochastic Lidenmayer system is studied by Monte Carlo simulations in this paper.The scattering coefficients are calculated in three methods:coherent addition approximation,tree-independent scattering,and independent scattering.
