Abstract

The invention discloses a video simulation method and device based on residual reconstruction, and the method comprises the steps: decoding a to-be-processed video through a sparse representation algorithm based on an initial sampling interval, and respectively obtaining a pre-sampling video frame, a post-sampling video frame and a sampling moment video frame; carrying out vectorization processing; calculating a predicted value of a measurement vector at a sampling moment, and obtaining a corresponding adaptive sampling interval; reconstructing the measurement vector at the sampling moment based on the initial sampling interval and the self-adaptive sampling interval; decoding the reconstructed sampling moment measurement vector to obtain an adaptive sampling moment video frame; and performing simulation output by using the decoded adaptive sampling moment video frame. According to the video simulation method and device based on residual error reconstruction provided by the embodimentof the invention, through a specific algorithm based on residual error reconstruction, video simulation can adjust different sampling intervals according to real-time images, the effect of video simulation is improved, and the intelligent process of simulation sampling is promoted.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video simulation method and device based on residual reconstruction. Background technique [0002] With the popularization of broadband and the development of computer technology, the use of sampling technology to simulate received video, real-time detection and monitoring of fortified areas is an important means to assist public security departments to maintain social stability. , hotels, sports and other fields play an important role. [0003] Nowadays, video surveillance all uses the method of allocating the same sampling interval at any time period to realize the collection and simulation of image resources. However, the inventors have found through research that, in the monitoring of traffic roads, for example, when going to work in the morning rush hour or after get off work The change of the evening peak is more complicated. On the contrary, in the time period o...
