Отрывок: Estimating the quality of an image resizing and rota- tion algorithms. Execution of any transformation of an image with purposes of resizing or rotating causes a dis- tortion of the source information, the degree of which de- pends on the used transformation method. Judging by the available information on the Internet, the quality of trans- formed image is usually estimated visually, which is not acceptable because of the ambiguity v...

Аннотация : | This paper is devoted to application of gradients field characteristics in selected problems of image intellectual analysis and processing. To analyse the properties and structure of an image several approaches and models based on the use of the gradients field characteristics, are proposed. In this paper, models based on Weibull distribution are considered, an image dominant direction estimation algorithm using the parameters of scattering ellipse of gradients field components is proposed, and a similarity measure of two images with arbitrary dimensions and orientation is proposed. Some examples of applications of these models for estimation of blur and structuredness of an image, for the quality assessment of resizing and rotating algorithms, as well as for detection of a specified object on the image delivered by an unmanned aerial vehicle, are given. |
