为了提取区域边界，可以对图像直接运用一阶微商算子或二阶微商算子，然后根据各像点处的微商幅值或其他附加条件判定其是否为边界点。如果图像中含有较强噪声，直接进行微商运算将会出现许多虚假边界点。-.Using the feature of distinct edge contour existing between the text and the background regions in color images, a novel text extraction algorithm—CEMA(Co

这是使用基于边缘的方法对文本图像中的文字进行检测的算法，可以将图像中的文字提取并标记出来。-This is the way to the edge-based text in the image text detection algorithm can extract the text in the image and mark them.
