Problems solved by technology

Even though the multi-scale coarse-to-fine blur kernel estimation method is widely used and achieves good results, and richer image details can be obtained in image restoration, the calculation amount of the multi-scale iterative process tends to gradually increase with the number of iterations, resulting in the overall The image restoration process takes too much time, so it is not suitable for fast deblurring scenes

Abstract

The invention relates to the technical field of image processing, in particular to a single-scale motion blurred image frame restoration method for a cab environment, which comprises the following steps: carrying out iterative training on a restoration model to obtain a trained restoration model; and inputting the motion blurred image frame and the optimal blurred kernel into a trained recovery model, recovering the motion blurred image by the recovery model, and outputting the recovered image. Compared with a multi-scale method, the method has the advantages that the overall structure of theblurred image can be better recovered, the running time can be obviously shortened, and the image frame recovery efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a single-scale motion blurred image frame restoration method for the driver's cab environment. Background technique [0002] In recent years, as the research on computer vision theory has become more and more mature, it has become possible for machines to recognize human behavior. Car cockpit behavior recognition is a good early warning method for distracted driving and abnormal events, because the cockpit environment is more fixed than other human body recognition scenarios. However, the driving environment of the car often has the problem of motion blur in the monitoring image frame due to rough roads and acceleration and deceleration problems. The blurred image frame will affect the judgment of subjective vision and machine vision. Among them, the problem of motion blur is caused by the relative displacement between the imaging device and the subject at the moment of...
