A video stream image defogging processing method and display device

Abstract

The embodiment of the invention discloses a defogging processing method and a display device for video stream images, relates to the field of image processing, and provides a method synchronously performing defogging processing at the display screen end in real time based on an average filtering algorithm. The defogging processing method comprises the steps of obtaining a to-be-processed image frame; determining the environmental light intensity of all pixels in the to-be-processed image frame according to all the pixels in the to-be-process image frame and the distribution of the adjacent pixels of all the pixels on a color space, and determining global atmospheric light of the to-be-processed image frame according to the distribution of all pixels in a last image frame of the to-be-processed image frame in a color space and the distribution of all pixels of the last image frame after defogging processing is performed in a color space; performing defogging processing on all the pixels in the to-be-processed image frame according to the environmental light intensity and the global atmospheric light to obtain image frame data of the to-be-processed image frame after defogging processing is performed; accordingly, the above functions are achieved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a video stream image defogging processing method and a display device. Background technique [0002] Traditional display screens usually only provide simple brightness / contrast adjustment for image quality adjustment, and the display screen of video surveillance is easily affected by bad weather. Therefore, security display screens serving intelligent traffic monitoring, community safety monitoring, etc. There is a strong need for real-time defogging. [0003] Most of the current mainstream dehazing algorithms are based on the principle of dark channel prior. Although the dehazing technology based on dark channel has good adaptability to common fog scenes, the effect is remarkable, and it is widely used. However, due to the complexity of this algorithm , so the dark channel-based defogging technology is difficult to meet the real-time processing requirements for large-sca...
