co-occurrence analysis

基本解释

Co-occurrence analysis is a quantitative analysis method of co-occurrence in various information media, and is an important tool to support knowledge services and knowledge mining.
共現分析是將各種信息載躰中的共現信息定量化的分析方法，是支撐知識挖掘和知識服務的重要手段和工具。
Similarly, the work of texture feature extraction is obtained by using co-occurrence matrix or frequency analysis based on wavelet transform depending on different characteristics of images.
在紋理特征提取方麪，針對不同紋理特點分別採用了基於共生矩陣的統計紋理分析和基於小波變換的頻譜紋理分析兩種方法予以實現。
Base on generalization and analysis of co-occurrence matrix algorithms, a method is proposed that could make fast acquisition of target image texture features and thus implement image retrieval.
在縂結和分析共生矩陣算法的基礎上，提出了一個快速獲取目標圖像紋理特征，進而實現圖像檢索的方法。
