ieee一种基于混沌的新加密方法An Image Encryption Scheme Based on Chaotic Map - In this paper, a novel block digital image encryp- tion scheme based on a chaotic coupled map lattices (CML) is reported. Within this scheme, an original image is decomp

A block-based transformation algorithm is proposed for image security using a combination of image transformation and encryption techniques. This algorithm will be used as a pre-encryption transform to confuse the relationship between the origi

to find correlation coefficient between encrypted and original image

Image / Picture Quality Measures In this application, different image quality measures are calculated for a distorted image with reference to an original image. To test the application, a set of 20 distorted images i ncluded in this package. The

图像的相关系数是衡量两幅图像的相关程度的,本代码直接通过选定区域计算出相关系数！-Image correlation coefficient is a measure of the relevance of the two images, this code directly through the selected area to calculate the correlation coefficient.
