  1. After completing the mctf using db2 wavelet, it is well integrated with discrete wavelet transform ( dwt ) and embedded zero tree wavelet. it uses atom structure to organize the coded bit - stream to achieve the brilliant combination of three scalabilities : temporal, spatial and psnr scalabilities. and the software platform is based on vc + + 6. 0

    在基於db2小波的運動補償時域濾波方法實現之後，本文將之和離散小波變換（ dwt ） 、嵌入式零樹編碼進行有機結合，並採用基於基本原子粒的數據流組織結構將分層后的數據流有效地組織起來，實現了具有時間、空間、質量三方面的完整可伸縮性的編解碼系統，系統的軟體平臺基於vc + + 6 . 0實現。
  2. Currently, transforming coding is one of the most used approach for image coding, where the discrete cosine transform ( dct ), the discrete wavelet transform ( dwt ), and the lapped biorthogonal transform ( lbt ) are widely utilized. how to reduce the complexity of these discrete transforms, is the key technique to image compression. in this thesis, a type of lapped biorthogonal transform which can map integers to integers is considered

    變換編碼是圖像壓縮中的主流方法，其採用的主要變換有離散餘弦變換、離散小波變換、雙正交疊式變換，如何減少這些離散變換的計算復雜性，一直是圖像壓縮研究的重要課題。
  3. Secondly, this paper presents a digital watermarking technique based on discrete wavelet transform ( dwt ) with human visual properties considered

    其次，比較全面地介紹了當前各種視覺模型，並提出一種結合視覺模型的dwt域水印演算法。
  4. Continuous wavelet transform ( cwt ) is the strong tool to analysis the non - steady signals, also it ' s algorithm is more suitable for data compression than that of discrete wavelet transform ( dwt )

    而連續小波變換（ cwt ）是分析非平穩信號的有力工具，且其演算法在數據壓縮等方面的性能優于離散小波變換。
  5. The discrete wavelet transform ( dwt ) technique has been widely used in signal processing and image processing

    離散小波轉換的技術，已被廣泛的應用於訊號分析與影像處理的問題上。
