图像信息测度在边缘检测中的应用

An application of image information measure to edge detection

介绍了信息测度的计算方法及以邻域一致性测度,并用算例说明用图像信息测度提取边缘的基本方法。结果表明,信息测度技术提取边缘信息时能够充分表征边缘点的特征,而且具有良好的抗噪能力。

The information measure is important parameter reflecting edge characteristic of image. Three basic features of edge point have been represented by using information measure technology to distill edge information. This article has introduced computing method of information measure and basic method of distilling edge information using image information measure with nearby area consistency measure for example. After the experiment, it has been expressed that the basic features of edge point have been represented using information measure technology to distill edge information and there has been a good ability to resist voice.
