“…However, because of the technology available at the time of publication, their system throughput is far from modern requirements. Marcelo de Oliveira et al [19] successfully implemented Levenberg-Marquardt method in low end platforms using VHDL. They showed that hardware implementation results maintain a strong correlation with software solution, despite reduced precision due to usage of fixed point arithmetic.…”

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.
