Opis:
This paper presents a hardware architecture of the video quality assessment module. Two different metrics were implemented on FPGA using modern High Level Language for digital system design – Impulse C. FPGA resources consumption of the presented module is low, which enables module-level parallelization. Tests conducted for four modules working concurrently show that 1.96 GB/s throughput can be achieved. The module is capable of processing 8K video stream in a real-time manner i.e. 30 frames/second. Such high performance of the presented solution was achieved due to the series of architectural optimization introduced to the module, such as reduction of data precision and reuse of various module components.

Opis:
In this paper the application of the combined video quality assessment method as well as some other recently developed objective metrics for the analysis of the results of the nonlinear colour video filtering is discussed. The spatio-temporal versions of colour image filtering methods, including the Vector Median Filter, can be obtained using frame-by-frame approach but the proper choice of the spatio-temporal kernel weights and the colour space used during filtration should be based on a reliable video quality assessment. In some earlier papers the combined video quality assessment method has been proposed, which has a highly linear correlation with subjective quality scores and can be extended into the colour version. As the illustration of the problem, some results of the colour video denoising using the spatio-temporal VMF, also in a weighted version, together with the quality assessment results have been presented in the paper.

Opis:
The video resolutions used in a variety of media are constantly rising. While manufacturers struggle to perfect their screens, it is also important to ensure the high quality of the displayed image. Overall quality can be measured using a Mean Opinion Score (MOS). Video quality can be affected by miscellaneous artifacts appearing at every stage of video creation and transmission. In this paper, we present a solution to calculate four distinct video quality metrics that can be applied to a real-time video quality assessment system. Our assessment module is capable of processing 8K resolution in real time set at a level of 30 frames per second. The throughput of 2.19 GB/s surpasses the performance of pure software solutions. The module was created using a high-level language to concentrate on architectural optimization.

Opis:
This paper presents a newly designed stereoscopic video quality metric. Overall insights towards the creation of mechanisms utilized within the genuine metric are presented herein. Delivery of the core information and motivation behind the features implemented, as well as functionality of the Compressed Average Image Intensity (CAII) quality metric are of utmost importance. The mechanisms created might be characterized as an objective, reliable and versatile quality evaluation tool for advanced analysis of the content delivery chain within stereoscopic video services.
