Image Retrieval Method Based on Combined Euler Vector and Edges Direction Histogram
Hong Yang · 2012
How to retrieve and query images effectively is an important research topic in the image database. An image retrieval method is proposed which integrates combined Euler vector and edges orientation histogram( EOH) . Firstly,the combined Euler vector feature is extracted from the edge images for image retrieval ( EEXO algorithm) . Then,to make a distinction among the images which have different shapes and similar Euler features,an image retrieval algorithm named EEXOEOH is presented which combines the EEXO algorithm and the EOH algorithm. The experimental results demonstrate that EEXOEOH has higher retrieval efficiency than the other four algorithms.
