Underwater Image Quality Assessment: Benchmark Database and Objective Method

IEEE transactions on multimedia
Underwater image quality assessment (UIQA) plays a crucial role in monitoring and detecting the quality of acquired underwater images in underwater imaging systems. Currently, the investigation of UIQA encounters two major challenges.

Graph-Represented Distribution Similarity Index for Full-Reference Image Quality Assessment

IEEE Transactions on Image Processing
In this paper, we propose a graph-represented image distribution similarity (GRIDS) index for full-reference (FR) image quality assessment (IQA), which can measure the perceptual distance between distorted and reference images by assessing the ...

Blind image quality assessment

Proceedings. International Conference on Image Processing, 2003
Blind image quality assessment refers to the problem of evaluating the visual quality of an image without any reference. It addresses a fundamental distinction between fidelity and quality, i.e. human vision system usually does not need any reference to determine the subjective quality of a target image.

Water quality assessment by image processing

2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015
We deal with a water quality assessment using an image processing methods in this article. Our suggested method for measurement of the water quality uses two well-known biological organisms sensitive to water toxicity. Their names are Daphnia magna and Lemna minor and they are frequently used for a water analysis from an ecotoxicology point of view. In

Continuous assessment of perceptual image quality

Journal of the Optical Society of America A, 1995
The study addresses whether subjects are able to assess the perceived quality of an image sequence continuously. To this end, a new method for assessing time-varying perceptual image quality is presented by which subjects continuously indicate the perceived strength of image quality by moving a slider along a graphical scale.

METHOD FOR ASSESSING IMAGE QUALITY

2009
The invention is a method for assessing image quality value of a distorted image with respect to a reference image. The method comprises the following steps: - computing (22, 23, 24), for each pixel of the distorted image, at least one quality level with respect to the reference image; - adding (25), for the distorted image, the quality levels ...
