After reviewing wavelet theory, pyramid wavelet decomposition was introduced to texture representation, we discussed the problem of optimal window size for texture feature extraction method ; the problem of local statistical feature value refinement has been studied, and a refinement method has been given which can decrease the boundary effect in calculating the feature value
在敘述小波分析理論的基礎上，把金字塔小波分解引入到紋理表示中來，討論了提取紋理特徵值時選取窗口大小的問題；研究了局部統計特徵值的改進問題，給出了一種對所提取的紋理特徵值的改進演算法，一定程度上克服了計算紋理特徵時的邊界效應。 -
In feature extraction step, we apply homogeneity into text detection, and we compare using the gradient, edge extract and homogeneity mapping to enhance corners and texture features, and then use a slip window to get different kinds of texture features as the feature vector, and then after comparing the accuracy result of svm and bp neural network, we choose svm as the classifier
在特徵提取步驟中，本文把一致性h應用到文本區域提取領域，使用邊緣空間映射和一致性h空間映射兩種方法得到特徵圖像，並比較了兩種空間對于文本提取的影響;對得到特徵圖像，使用滑動窗口比較了提取不同維數的紋理特徵作為特徵向量的結果。 -
Tool wear image characteristic was studied at tool wear inspecting aspect and put forward " 十 window " automatic edge detection algorithm and resolved the problem of tool wear image edge extraction. the algorithms and programs calculating area, perimeter, width and length for tool wear image were developed for tool wear image. the better results were gained by experiments and improved edge orientation precision and geometry measure precision
