Color fusion method of night vision weak light image and infrared image based on color transfer

Abstract

The invention discloses a color fusion method of a night vision low-light image and an infrared image based on color transfer. The present invention first linearly fuses visible light and infrared images to obtain the , , and components of the gray-scale fused image. Utilize the brightness and color distribution of the reference image to adjust the gray-scale fusion image, and adjust the adjusted image data from YUV space back to RGB space to obtain the final color fusion image. The fusion image obtained by the method of the present invention and the color reference The brightness distribution of the image is similar and has a good visual effect.

Description

technical field The invention belongs to the field of image processing, and relates to a fusion method of a visible light image and an infrared image based on color and brightness transfer. Background technique The fusion of infrared and visible light heterogeneous images can improve the target detection ability and reveal the features of the target that cannot be detected when observed in a single image, which has important application value in the fields of security and assisted driving. Especially in the night driving assistance system, the effective processing of light images can greatly expand the driver's visual distance and improve safety. Improve the color information of the image and display the fused image in a natural color suitable for human observation, which can significantly improve the recognition performance of the human eye and reduce the operator's fatigue. Patents based on color space transformation include: Unified adjustment method for multi-tone colo...
