Example Embodiment

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] like figure 1 As shown, it is a flow chart of the first embodiment of the present invention, which provides an image detection method, which is based on feature fusion for near-duplicate image detection for real-time detection of near-duplicate images in an image set. The approximate duplicate image in this method mainly refers to different images formed by cropping, rotating, scaling, brightness and contrast changes, color adjustment, adding logos and other image editing methods for the same image source. The method specifically includes,

Abstract

The invention relates to the field of image processing, and provides an image detection method, and the image detection method comprises the steps of preprocessing an inputted image; extracting characteristics of the preprocessed image and compressing the preprocessed image; and contrasting the characteristics of the compressed image, judging the characteristic as similarity if the characteristics satisfy a judgment condition, and otherwise judging the characteristic as dissimilarity. The invention also provides an image detection system. By adoption of the technical scheme, the requirement for real-time detection can be met, and the detection effect of the approximately repeated image can be guaranteed.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image detection method and system. Background technique [0002] With the rapid development of electronic imaging technology and digital image processing technology, the cost of image data collection, storage and editing has become increasingly low. Every day, tens of thousands of image data are generated and released, and these images are edited through different tools. , conversion and other operations into other multiple versions, and then distributed through the network. The increasingly convenient and simple image duplication, editing, and distribution technologies have resulted in more and more duplicate and unhealthy image information on the Internet. How to detect and filter near-duplicate images has become an increasingly important technology. [0003] CN101470730 discloses an image duplication detection method based on frequency spectrum features. The method extracts...
