Visual quality assessment using a contrast gain control model
نویسنده
چکیده
Much of the work on visual quality assessment has been devoted to gray-level images; metrics taking into account color information and the temporal component are still relatively rare. This paper presents a quality metric for color video which is based on a recent contrast gain control model of the human visual system. It is used to assess the quality of MPEG-coded sequences and exhibits a behavior that is consistent with subjective ratings.

Assessment of Contrast Media Volume Injected and Image Contrast in Abdominal Pelvic CT Scan and Related Factors in Referral Hospitals in Mazandaran, Iran
Background and purpose: Computed tomography scan (CT) is highly capable of diagnosing abdominal and pelvic lesions. Injection of contrast media at appropriate concentration and volume provides the least side effects and the highest image quality. This study aimed at investigating the volume of contrast medium injected and the level of image contrast compared to the standard model, in the imagi...
متن کاملDesign principles for contrast gain control from an information theoretic perspective
Contrast gain control is an important and common mechanism underlying the visual system’s adaptation to the statistics of the visual scenes. In this paper, we first showed that the threshold and saturation determine the preferred contrast sensitivity as well as the maximum information coding capacity of the neuronal model. Then we investigated the design principles underlying adaptation behavio...
متن کاملImage Enhancement Using an Adaptive Un-sharp Masking Method Considering the Gradient Variation
Technical limitations in image capturing usually impose defective, such as contrast degradation. There are different approaches to improve the contrast of an image. Among the exiting approaches, un-sharp masking is a popular method due to its simplicity in implementation and computation. There is an important parameter in un-sharp masking, named gain factor, which affects the quality of the enh...
متن کاملJust Noticeable Difference Estimation Using Visual Saliency in Images
Due to some physiological and physical limitations in the brain and the eye, the human visual system (HVS) is unable to perceive some changes in the visual signal whose range is lower than a certain threshold so-called just-noticeable distortion (JND) threshold. Visual attention (VA) provides a mechanism for selection of particular aspects of a visual scene so as to reduce the computational loa...
متن کاملAn image-computable psychophysical spatial vision model.
A large part of classical visual psychophysics was concerned with the fundamental question of how pattern information is initially encoded in the human visual system. From these studies a relatively standard model of early spatial vision emerged, based on spatial frequency and orientation-specific channels followed by an accelerating nonlinearity and divisive normalization: contrast gain-contro...
