Problems solved by technology

One of the methods often used in the past to identify synthetic images is the color comparison method. This method is mainly to check the color information. The image can be enlarged with special software to analyze the possible or suspicious color areas and analyze the authenticity of the color. The disadvantage is that it takes a lot of time and there is no feasible system to apply

Embodiment Construction

[0017] The invention provides a simple synthetic image detection method in a content-based retrieval system: first, input the image to be identified into the retrieval system, search for many images with similar characteristics, and then use the matrix representation technology of the image to combine the input image with the The searched images are subtracted, and according to the distribution of the zero values ​​of the subtracted images, it is judged whether the images have been synthesized.

[0018] First introduce the image retrieval system adopted by the present invention below.

[0019] With the rapid development of digital image applications, accurate and efficient image retrieval technology has been paid more and more attention. For the current search engine system, the user usually submits the text, and then the system returns the image related to the text; while for the content-based image retrieval system, the user submits the image, and the system returns the simi...

Abstract

The invention belongs to the technical field of image detection, and relates to a composite image detecting method based on image search. The method comprises the following steps: inputting an image which is to be detected whether to be a composite image in a content-based image search system, searching, and selecting an image with the highest matching degree from the searched matched images; and adjusting the image to be detected and the searched image with the highest matching degree to the same size, subtracting, and performing the following judgments: a, if the subtracted image has a large area of black part or a small area of continuous black part and a large area of continuous white region, proving that at least one of the two images is processed; and b, if the subtracted image has a large area of white region and smaller and scattered black regions, judging that the relation between two images is small, i.e., the image is not processed. The detecting method is simple, intuitive, low in time complexity and easy for application.

Description

technical field [0001] The invention belongs to the technical field of image detection, in particular to the field of content-based image content credibility measurement. Background technique [0002] With the rapid development of various image processing technologies, image counterfeiting has gradually become an important issue in the field of graphics and images. One of the methods often used in the past to identify synthetic images is the color comparison method. This method is mainly to check the color information. The image can be enlarged with special software to analyze the possible or suspicious color areas and analyze the authenticity of the color. The disadvantage is that it takes a lot of time and there is no feasible system to apply. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a simple and easy detection method for synthetic images. For this reason, the pr...
