Abstract

The invention discloses a near-duplicate image detection method. The method comprises the steps that a training image set is obtained, and according to the images in the training image set, a multi-vision word bank is learned and obtained; based on the learned multi-vision work bank, local characteristics of a to-be-detected image and images in an image database are coded into nonnegative sparse vectors in a nonnegative sparse coding method; via regional integration and spatial combination of the nonnegative sparse vectors, histogram vectors of the to-be-detected image and the images in the image database are obtained; and according to the similarity between tolerance images of the histogram vectors of the to-be-detected image and the images in the image database, an image, near-duplicate to the to-be-detected image, in the image database is output.

Description

Technical field [0001] The present invention relates to the field of computer vision, in particular to a near-duplicate image detection (Near-duplicate Image Detection) technology. Background technique [0002] With the rapid development of multimedia technology and related electronic processing technology, as an effective way of dissemination of information, digital images are experiencing a period of rapid development. The number of images on the Internet is exploding, which is inevitable. Approximately repeated images, which bring great inconvenience to information storage and user retrieval. Therefore, approximate repeated image detection has attracted the interest of some scholars. Through the research of similar repeated image detection, on the one hand, image copyright protection can be realized. On the other hand, if it is applied in an image search engine, it can be used to filter out the repeated images in the search results, thereby improving the user's search quality...
