  • code : n 1 法典;法規。2 規則,準則;(社會、階級等的)慣例,習俗,制度。3 (電)碼,代碼,密碼,暗碼;...
  • invariance : 不變性不變式
  1. We propose an algorithm, which integrate the shift invariance of redundant discrete wavelet transformation ( rdwt ) and the flexibility of multi - resolution motion estimation, to overcome the shift variance of dwt and get the precise motion vector. under the different code parameter, we take the proposed algorithm compared to several present algorithms, and experiment results have shown that proposed algorithm could leave less energy in the residual frames, get more precise motion vector and better reconstructed frames

    文章最後在不同的編碼參數下,將所提演算法與兩種傳統小波域運動估計演算法作比較,根據實驗所得數據分析,發現所提演算法在性能上要優于另外幾種演算法,具體體現在運動估計后所得殘差幀能量更小,重構幀客觀與主觀質量更高。
  2. Fractal neighbor distance gives a quantitative measure of the input - output characteristics of the fractal code of an encoded image. the fundamental mechanism behind this recognition scheme lies in the uniqueness of the attractor of a fractal code. the attractor has the invariance to image translation, rotation, scaling and illumination

    分形鄰距是針對進行了分形編碼的圖像而定義的一種圖像間相似度的測距方式,它具有編碼的吸引子唯一不變性的特點,因而對旋轉、縮放、平移以及光照都有不變性,這樣可以很好實現正確識別。
