Automatic Image Quality Assessment (IQA) remains a difficult challenge due to the complexity of mimicking the Human Visual System (HVS) and the limitations of traditional objective Image Quality Metrics (IQM). Existing learnable methods often involve high computational costs and fail to adequately c…
Masking effect is one of the most important perceptual properties that could be modeled by estimating an adaptive threshold known as the just noticeable difference (JND) referring to the maximum difference not perceived by the human visual system (HVS). In this paper, a novel framework to extend 2D-…
In this paper, we propose a saliency-weighted stereoscopic JND (SSJND) model constructed based on psychophysical experiments, accounting for binocular disparity and spatial masking effects of the human visual system (HVS). Specifically, a disparity-aware binocular JND model is first developed using…
360- video is gaining a lot of interest because of the immersive feeling brought by such a technology. Several projection formats are used to represent this type of content. Equirectangular projection (ERP) is one of the most widely used projection scheme for 360 panoramic content. The main drawback…
Based on psychophysical experiments, we propose an asymmetric 3D just noticeable difference model (AJND) in the DCT domain taking into consideration the binocular properties of the human visual system (HVS), the background luminance and the spatial frequency of each DCT component. Subjective evaluat…
This paper proposes a novel approach for perceptually guiding the rate-distortion optimization (RDO) process within the High Efficiency Video Coding (HEVC) standard. The reference codec does not consider effectively the perceptual characteristics of the input video and further, the particular percep…
One of the most challenging issues in stereoscopic image quality assessment (IQA) is how to effectively model the binocular behaviors of the human visual system (HVS). The latter has a great impact on the perceptual stereoscopic 3D (S3D) quality. This paper presents a stereoscopic IQA metric based o…
