基于连通区域的仿射不变区域提取方法
Affine Invariant Region Extraction Method Based on Connected Region
摘要
Abstract
To resolve the problems of high computation and low robustness of existing affine invariant feature extraction methods, a new affine invariant region extraction method based on connected region is proposed. The input gray image is filtered with an anisotropic gauss filter and then histogram equalization is performed. Connected regions with the same pixel values are found. Adjacent connected regions whose gray values' difference is less than delta are merged. The ultimate merging result that satisfies the demand is concerned as the image's local affine invariant regions. Experiments show that this method is very effective, fast and highly robust.关键词
