Abstract

The present invention discloses an enhancement processing method and apparatus for a traffic video image. According to the method and the apparatus, the noise intensity is estimated and an image noise reduction process is guided according to continuous video image inter-frame information, a constraint weight of a neighborhood pixel region to a center pixel unit is introduced according to extracted local feature effective data, and a grey-scale mapping relationship function of the pixel unit is adaptively constructed, so that image noise suppression is more accurate, image local detail enhancement is more obvious, and further the effectiveness of a video image enhancement method in a complex scenario, especially a low-illumination environment is improved.

Description

technical field [0001] The present invention relates to the technical field of video image processing, in particular to an enhancement processing method and device for traffic video images. Background technique [0002] With the rapid development of the field of intelligent transportation, video image processing technology has gradually become a hot topic of research and has been widely used. Due to the complex and changeable imaging environment, as well as the interference of imaging device hardware and other factors, the gray scale distribution of the collected video images is easily severely uneven, resulting in the attenuation of video image quality. Video images are sometimes directly used as effective auxiliary evidence for judicial forensics. It is particularly important to be able to better present the key details of the target of interest in the image, such as the model of the vehicle on the road, the characters of the license plate, the facial features of the drive...
