Abstract

The invention discloses a video processing method, and a model construction method. The model construction method comprises the following steps: acquiring video data meeting a first preset condition; performing alignment processing on video sequences in the video data; processing the aligned video sequences to obtain video sequences meeting a second preset condition under different exposure durations; inputting the video sequences meeting the second preset condition and the video data meeting the first preset condition into a deep convolutional neural network model for training to obtain a target model. According to the invention, the technical problem of poor effect of reconstructing a high dynamic range video in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular, to a video processing method and a model building method. Background technique [0002] High Dynamic Range (Hereinafter referred to as HDR) video, compared with Standard Dynamic Range (Hereinafter referred to as SDR) video, the light and dark levels of the image are clearer, the image details are richer, and the real scene can be reproduced more realistically . With the development of HDR technology and the gradual popularization of HDR displays, the demand for HDR video is gradually increasing. True HDR video production requires the use of high dynamic range imaging devices at the acquisition end, and the use of HDR non-editing software during production, which means that HDR video content production has high requirements for shooting equipment and pre-processing technology. Therefore, the current HDR content is still relatively scarce. [0003] The current HDR...
