A Multi-annotated and Multi-modal Dataset for Wide-angle Video Quality Assessment
This addresses the problem of video quality assessment for wide-angle videos, which is crucial for applications like sports recording, but the work is incremental as it primarily introduces a new dataset.
The authors tackled the lack of a specialized dataset for wide-angle video quality assessment by constructing the first multi-annotated and multi-modal dataset (MWV), and found that state-of-the-art video quality methods show significant limitations when tested on it.
Wide-angle video is favored for its wide viewing angle and ability to capture a large area of scenery, making it an ideal choice for sports and adventure recording. However, wide-angle video is prone to deformation, exposure and other distortions, resulting in poor video quality and affecting the perception and experience, which may seriously hinder its application in fields such as competitive sports. Up to now, few explorations focus on the quality assessment issue of wide-angle video. This deficiency primarily stems from the absence of a specialized dataset for wide-angle videos. To bridge this gap, we construct the first Multi-annotated and multi-modal Wide-angle Video quality assessment (MWV) dataset. Then, the performances of state-of-the-art video quality methods on the MWV dataset are investigated by inter-dataset testing and intra-dataset testing. Experimental results show that these methods impose significant limitations on their applicability.
