In this work we comprehensively categorize image quality measures, extend measures defined for gray scale images to their multispectral case, and propose novel image quality measures. They are categorized into pixel difference-based, correlation-based, edge-based, spectral-based, context-based and human visual system (HVS)-based measures. Furthermore we compare these measures statistically for ...

Stereoscopic/3D image and video quality assessment (IQA/VQA) has become increasing relevant in today’s world, owing to the amount of attention that has recently been focused on 3D/stereoscopic cinema, television, gaming, and mobile video. Understanding the quality of experience of human viewers as they watch 3D videos is a complex and multi-disciplinary problem. Toward this end we offer a holis...

This paper proposes a measure of quality for evaluating the performance of region-based segmentation methods. Degradation mechanisms are used to compare segmentation evaluation methods onto deteriorated ground-truth segmentation images. Experiments showed the significance of using degradation mechanisms to compare segmentation evaluation methods. Encouraging results were obtained for a selectio...

INTRODUCTION The Spies™ system (Karl-Storz®) was introduced into digital ureteroscopy to improve endoscopic vision. To date, there is no data to either indicate which of the Spies modalities is better for improving diagnosis and treatment procedures, nor to compare the modalities in terms of image quality. The aim of this study was to evaluate and compare the image quality of five Spies™ modali...

Color image quality is becoming an increasingly important factor in the consumer imaging industry. Users of imaging devices such as Multi-Function Peripherals (MFP) have increasing expectations to the quality of the reproduced images. In this paper we address the subject of color image quality from a practical point of view, and from the point of view of a provider of imaging technology for con...

The paper is devoted to the subjective image quality evaluation for selected highly efficient compression standards. The experimental verification was done for the seven-segment display image test.

Fractal techniques for image compression have recently attracted a great deal of attention. Fractal image compression is a relatively recent technique based on the representation of an image by a contractive transform, on the space of images, for which the fixed point is close to the original image. This broad principle encompasses a very wide variety of coding schemes, many of which have been ...

Many image quality and image difference metrics have been proposed over the last decades. An important factor when evaluating the image quality or image difference is the viewing distance. In this paper we propose a new image difference metric based on the simulation of detail visibility and total variation. The simulation of detail visibility by using shearlets takes into account the viewing c...

In this paper, we propose a new statistical approach to investigate the performance of some objective quality metrics used in the literature in order to determine the most suitable quality metric for watermark transparency evaluation. To this end, we have defined a new procedure based on the ANOVA (ANalysis Of VAriance) tests and the subjective performance evaluation. Firstly, a set of selected...
