Moving image processing device and moving image processing method

Abstract

The invention relates to a moving image processing device and a moving image processing method. The device and the method are based on an atmosphere model so that videos in foggy days are clear, the image visibility is improved, and in addition, the real-time processing requirements of the images can be preferably met. According to the moving image processing device, in the video defogging process, the video is divided into a core frame used as a main frame and an ordinary frame used as a sub frame, the core frame is calculated again to be used as a distance parameter t(X) and an unplugged point parameter A, the ordinary frame is not subjected to A calculation, and the A of the core frame is used, the t(X) of a region corresponding to the core frame is used for the background part of the ordinary frame, and the t(X) is calculated again for the foreground part of the ordinary frame. According to the device and the method, the application speed of the single-frame image defogging algorithm based on the atmosphere model in the defogging clarifying processing on the moving images such as videos and the like can be accelerated, a good defogging effect can be obtained, and in addition, the real-time performance of the moving images is ensured.

Description

technical field [0001] The present invention relates to a moving image processing device and a moving image processing method, capable of clearing moving images captured in foggy, sandy and dusty weather (hereinafter referred to as "foggy video"). Background technique [0002] The quality of outdoor video surveillance is usually affected by severe weather such as heavy fog and sandstorms. Due to the severe decrease in visibility, the details of the video and the information of the remote monitoring scene are lost. Moreover, outdoors, there are many monitoring application scenarios, climate changes are complex, and fog and dust weather often occur, especially in urban roads and expressway environments, which are more frequent and severe. Therefore, in foggy and dusty weather, improving video clarity has become an urgent need in the field of video surveillance. Although the existing video camera products have the function of clearing the video, that is, the defogging function...

Problems solved by technology

However, one of the disadvantages of these methods is that the algorithm speed is too slow and the real-time performance is poor.

However, the single-frame dehazing algorithm in this patent document 1 is a simple histogram equalization image enhancement method, which is not designed for the dehazing environment, and the effect is not ideal
