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
在特征提取步骤中,本文把一致性h应用到文本区域提取领域,使用边缘空间映射和一致性h空间映射两种方法得到特征图像,并比较了两种空间对于文本提取的影响;对得到特征图像,使用滑动窗口比较了提取不同维数的纹理特征作为特征向量的结果。
