Stereoscopic imaging is becoming increasingly popular. However, to ensure the best quality of experience, there a need develop more robust and accurate objective metrics for stereoscopic content assessment. Existing image video are either extensions conventional 2-D (with added depth or disparity information) based on relatively simple perceptual models. Consequently, they tend lack accuracy robustness required This paper introduces full-reference human visual system (HVS) model...

Stereoscopic video quality assessment has become a major research topic in recent years. Existing stereoscopic metrics are predominantly based on image extended to the time domain via for example temporal pooling. These approaches do not explicitly consider motion sensitivity of Human Visual System (HVS). To address this limitation, paper introduces novel HVS model inspired by physiological findings characterising sensitive response complex cells primary visual cortex (V1 area). The proposed...

Consumer Electronics (CE) devices have started to support 360° videos in order improve the perceived video quality by consumers. Higher compression not only lead improved consumer perception, but also efficient energy and storage usage CE devices. Consequently, of such content is becoming a critical design consideration To this end, paper first proposes residual weighting algorithm that utilizes features Weighted Craster Parabolic Projection Peak Signal-to-Noise Ratio (WCPPPSNR), instigate...

360° videos are represented in spherical projection formats and the video quality of such is assessed using objective metrics. Furthermore, between two different can be evaluated Cross Craster parabola, a 2D cross format which used by Parabolic Peak Signal-to-Noise Ratio (CPPPSNR) metric. The existing CPPPSNR measurements do not consider subsampling locations during assessment to match pixel density sphere. Nevertheless, it vitally important account for oversampled sphere order compatible...

It is vital that video encoders remove redundant information present in the spherically projected 360° frames. To this end, paper proposes a novel weighted residual technique and an integrated between proposed state-of-the-art adaptive quantization technique. The methods adapt to spherical characteristics order reduce magnitude of information. tests with All-Intra configuration using Versatile Video Coding (VVC) test model, produce average bit rate savings 0.91% 1.35% regards various...

Video Quality Assessment (VQA) is an integral part of any video coding processes. The Versatile Coding (VVC) applies Peak Signal-To-Noise (PSNR) spherical objective quality metrics in the VQA 360° videos. However, these fail to display compatibility be integrated with rectilinear functionalities VVC. In response, this paper proposes Weighted Craster Parabolic Projection Signal-to Noise Ratio (WCPPPSNR), a novel metric for that improves existing CPPPSNR by providing support subjective...
