Problems solved by technology
Different video data combined with different linear deviation combinations may improve the accuracy of latent feature extraction or reduce the accuracy of latent feature extraction, and may even lead to the inability to effectively extract latent features.
This is because most of the existing matrix factorization techniques use complete linear deviations for latent feature extraction, and it is impossible to select the most suitable combination of linear deviations for different video data to obtain the most accurate decomposition results.

Description
technical field [0001] The invention relates to the field of computer image processing, in particular to a device and method for extracting main features of linear deviation of video data. Background technique [0002] Video data feature extraction, as one of the most important links in computer image processing, has always been the main problem and research hotspot in computer science and engineering. Since video data can be converted into high-dimensional sparse data matrix, matrix decomposition technology can be used to obtain Extracting latent features from the specified video data to reveal the underlying rules and meanings contained in the video data is a major technology for feature extraction. [0003] At present, many existing technical methods are based on the pixel domain. Among them, the matrix decomposition technology has been able to combine linear deviations and extract latent features from video data. But at present, linear deviation is divided into two cate...
