分析了国内外图像阴影边缘检测方法的不足,提出一种基于粗糙集理论的边缘检测新方法,阐述了利用粗糙集条件属性和边缘点梯度等特点对图像边缘点进行分类以及提取阴影边缘的方法,通过实验验证了边缘检测效果。

-Has analyzed the domestic and foreign image shadow marginal check method insufficiency, proposed that one kind based on the rough collection theory s marginal check new method, elaborated use rough collection characteristics and so on condition attribute and peripheral point gradient carry on classified as well as the extraction shadow edge method to the image peripheral point, through experimental verification marginal check effect.
