Image processing method and device and computer readable storage medium

Abstract

The invention provides an image processing method and device and a computer readable storage medium, which are used for inhibiting the black and white edge phenomenon in a fused image, so that the overall presentation effect of the image is more natural. The method comprises the following steps: respectively carrying out multi-scale decomposition on a visible light image and an infrared image to obtain a multi-scale decomposition result; for each pixel point position, determining whether the pixel point position is in a feature region or not according to the multi-scale decomposition result; if yes, correcting the infrared high-frequency information corresponding to the position of the pixel point according to the multi-scale decomposition result; and after correcting the infrared high-frequency information corresponding to all the pixel positions in the feature region, performing coefficient fusion and multi-scale reconstruction processing on the infrared image and the visible light image to obtain a fused image without a black-white edge phenomenon.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method, device and computer-readable storage medium. Background technique [0002] With the continuous improvement of people's monitoring requirements, image fusion technology has become one of the popular technologies of video monitoring. In the image fusion method in the prior art, generally, the collected visible light image and the infrared image are registered first, so that the pixel positions of the two images correspond one-to-one, and then fusion processing is performed. The fusion algorithm usually adopts the transformation domain method, which decomposes the visible and infrared images into high and low frequencies respectively, and obtains the fused image through coefficient fusion and multi-scale reconstruction. [0003] The transform domain fusion method can obtain detailed and colorful fused images in low-light environments. However, if ...

Problems solved by technology

[0003] The transform domain fusion method can obtain detailed and colorful fused images in low-light environments. However, if there are objects in the scene with different reflectances for the visible spectrum and the infrared spectrum, the image will be fused on the edges of these objects. Black and white edges, resulting in poor overall image rendering
