SIMILARITY ACQUISITION METHOD FOR COLOUR DISTRIBUTION AND TEXTURE DISTRIBUTION IMAGE RETRIEVAL

摘要

Disclosed is a similarity acquisition method for colour distribution and texture distribution image retrieval, which relates to the technology of image retrieval. The key technical points of the present invention comprise: extracting a colour distribution feature and a texture distribution feature of an input image; respectively calculating the similarity between the colour distribution feature of the input image and a colour distribution feature of each image in a database, so as to obtain the colour distribution feature similarity Sa (i) between the input image and each image in the database; respectively calculating the similarity between the texture distribution feature of the input image and a texture distribution feature of each image in the database, so as to obtain the texture distribution feature similarity Sb (i) between the input image and each image in the database; and using the formula S (i) = Wa * Sa (i) + Wb * Sb (i) to calculate the combined similarity S (i) between the input image and each image in the database.
