Embodiment Construction

[0068] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0069] Please refer to figure 1 , figure 1 It is a flow chart of a deep-sea video subjective quality evaluation method based on dynamic optimization of psychometric theory in the present invention. This method analyzes the subjective and objective factors in the formation process of deep-sea video, designs a subjective evaluation method that conforms to the actual collection and use of typical deep-sea video, and studies the optimization strategy to maximize the evaluation validity under limited resources. Based on the evaluation process and evaluation criteria determined by the subject, this method conducts on-the-spot surveys of experts in marine and related fields to obtain qualitative data on the usefulness of deep-sea video science, and uses quantitative analysis methods to generate semantic metrics for deep-sea video qualit...

Abstract

The invention relates to a psychological measurement dynamic optimization-based subjective deep-sea video quality assessment method. The method comprises the following steps: Step S1, semantic measurement of deep-sea video quality; Step S2, designing of deep-sea video quality subjective assessment; and Step S3, performing of a discrete fechner psychological measurement-based subjective quality dynamic optimization assessment strategy. The psychological measurement dynamic optimization-based subjective deep-sea video quality assessment method has the advantages that once the psychological measurement dynamic optimization-based subjective deep-sea video quality assessment method disclosed by the invention is put into operation, the following technical effects can be achieved: scaling is performed from the angle of scientific usefulness; during subjective view quality assessment of a deep-sea video, reasonable scaling is made to the quality of a provided deep-sea video test sequence in principal accordance with a set assessment process and an assessment criterion; redundant assessment is reduced by dynamically tracking an assessment process; and the assessment efficiency can be effectively improved; time and human resources can be greatly saved under a condition of guaranteeing the precision, so that an aim of reducing the cost is fulfilled.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a deep-sea video subjective quality evaluation method based on dynamic optimization of psychometric theory. Background technique [0002] Underwater video technology has been applied to related research in shallow sea environment for more than 60 years, and has played an important role in promoting marine biological ecological research, fish species research, underwater object detection and tracking, etc. In recent years, with the continuous development of deep-sea exploration technology, unmanned or manned deep-sea submersibles carrying camera equipment can shoot deep-sea videos in the deep-sea area of ​​​​10000 meters to 10,000 meters. In December 2016, the "Zhang Jian" scientific research ship of Shanghai Ocean University carried the self-developed "Rainbow Fish" deep submersible to carry out the 10,000-meter abyss scientific research in the high seas of the Southwest...
