In this paper, a No-Reference method is proposed for quality assessment of an image resizing methods based on interpolation algorithms. Quality refers to the image blur. To this end, it is proposed to use a previously developed measure based on a sta

In this paper, a new measure for no-reference assessment of image quality based on the use of the structural properties of an image is proposed. As a measure, it is proposed to use the estimate of the Weibull distribution shape parameter, obtained by

The most digital image watermarking algorithms have nearly always been realised in red, green and blue (RGB) colour space. In this study, a secure, robust and imperceptible CDMA image watermarking scheme which uses discrete wavelet transform is propo

In this paper, the problems of detection of unauthorized changes to the content of a digital image, determination of distorted parts and partial recovering of the content from the damaged parts, are considered. most types of image tampering are based

A problem of surface imaging and parameter determination in an antenna far-field range by scanning the electromagnetic field intensity distribution in a plane combined with the imagined position of a test antenna aperture is considered. The signal at
