| description | The invention relates to the field of computer vision and pattern recognition, in particular to an online classroom concentration recognition method with a visual privacy protection function, which comprises the following specific steps of: firstly, performing style migration on video data to realize a visual privacy protection effect; image color features and significant structure features of the processed video frame sequence are extracted and mapped to an image visual privacy protection score, the recognition rate of concentration recognition is obtained from the processed video frame sequence, and finally a binary statistical model between the visual privacy protection score and the online classroom concentration recognition rate is established; aiming at the privacy conflict between video monitoring and intelligent application, the video data privacy protection method balances the conflict between privacy protection and intelligent application while performing privacy protection on the video data, and ha |
