Quality Evaluation and Nonuniform Compression of Geometrically Distorted Images Using the Quadtree Distortion Map
The paper presents an analysis of the effects of lossy compression algorithms applied to images affected by geometrical distortion. It will be shown that the encoding-decoding process results in a nonhomogeneous image degradation in the geometrically corrected image, due to the different amount of information associated to each pixel. A distortion measure named quadtree distortion map (QDM) abl...
متن کاملCorrection of geometrically distorted underwater images using shift map analysis.
In underwater imaging, water waves cause severe geometric distortions and blurring of the acquired short-exposure images. Corrections for these distortions have been tackled reasonably well by previous efforts but still need improvement in the estimation of pixel shift maps to increase restoration accuracy. This paper presents a new algorithm that efficiently estimates the shift maps from geome...
متن کاملPerceptual quality assessment of geometrically distorted images
Digital images are subject to various kinds of distortions that may result in a degradation of visual quality during acquisition, processing, compression, storage, transmission and reproduction. It is therefore necessary for many applications to be able to quantify the image quality degradation that occurs in a system, so that it is possible to control and enhance the quality of the images it p...
متن کاملPerceptual quality evaluation of geometrically distorted images using relevant geometric transformation modeling
One of the most active research area in the watermarking community is the research in dealing with geometric distortion. The geometric distortion problem has two aspects, namely its effect on watermark detectability and its effect on the perceptual quality of the watermarked data. Most research in this area has been concentrated on addressing the first aspect of the problem, and research on obj...
متن کاملon the relationship between using discourse markers and the quality of expository and argumentative academic writing of iranian english majors
the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
