Abstract:

 An image retrieval method for a design patent was proposed by means of a multifeature fusion method. A structure and edge direction histogram described shape features of the design patent images. Texture features were obtained by Gabor wavelet and statistical characteristics of image blocks. Image retrieval for design patents was accomplished with shape features and texture features integrated with a weighted method.

Key words: design patent, image retrieval, edge direction histogram, Texture features, multifeature fusion
