Problems solved by technology
[0003] Previously, the clarity of teaching videos on online learning platforms (such as seewo College) relied on manual subjective judgments. This judgment relied on the background experience of the auditors. The results of the review may lead to the inability to judge the video quality and perception of different people under a unified standard. At the same time, relying on manual review will also increase the time cost and the review efficiency is low.

The embodiment of the invention discloses a video recognition method and device, a storage medium and a terminal, and the method comprises the steps: obtaining a to-be-processed video, and determining at least one frame of image in the video; determining a definition score of each frame of the image, and calculating a target definition score of the video according to each definition score; and according to a comparison result of the target definition score and a preset definition threshold value, carrying out clear identification on the video. By adopting the embodiment of the invention, objective judgment can be carried out by calculating the definition score without depending on manual judgment, a brand new objective evaluation standard is provided for the impression quality evaluation of the teaching video, meanwhile, the time cost can be saved, and the examination efficiency can be improved.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to a video recognition method, device, storage medium and terminal. Background technique [0002] In today's education informatization, it is becoming more and more common for teachers to record course content in the form of video and transmit it for students to learn and use; the teaching forms of webcast and recorded lessons are also becoming more and more common, and high-quality video picture quality is especially important. The visual quality of video images directly affects the quality of teaching, and high-quality images help students learn more effectively from video courses. [0003] Previously, the clarity of teaching videos on online learning platforms (such as seewo College) relied on manual subjective judgments. This judgment relied on the background experience of the auditors. Different individuals have different grasps of the clarity of the picture qua...
