Multi-focus image fusion algorithm based on second generation Curvelet transform coupled with texture information adjustment
SHI Kunquan, and GAO Ying
At present, many image fusion algorithms mainly use image energy information to fuse image coefficients, ignoring the texture information of the image, which brings the defects of Gibbs and block phenomenon to the fusion results. This paper designs a multi-focus image fusion algorithm based on the second generation Cur

Image inpainting algorithm based on structural information constraint rule coupled with matching model
DAI Yuanquan, and LI Chao
In view of the fact that most image restoration algorithms rely on fixed size sample blocks to search for the best matching blocks, ignoring the structure information of the sample blocks, resulting in the discontinuity and ringing phenomenon of the repaired images. Based on the approximation between the sample block a

Image copy-paste tampering detection algorithm based on color constrained coupling distance penalty model
WANG Yazi, SUN Huaibo, and MA Yuankun
At present, many image tampering detection methods mainly measure the distance between image features to complete feature matching, ignoring the color information of the image, resulting in more false detection and missed detection in the detection results. In this paper, color information is introduced into the proces
