Abstract

The embodiment of the invention relates to an image processing method and device, electronic equipment and a storage medium, and relates to the technical field of image processing. The image processing method comprises the following steps: carrying out panoramic image segmentation on a first image to obtain a plurality of image areas, and classifying the plurality of image areas to obtain a plurality of categories; according to a gray level image corresponding to the first image and a second image, independently carrying out local color mapping on an image area where each category in the first image is located, and determining a mapping relation between pixels of the first image and pixels of the second image; and mapping the second image according to the mapping relation to obtain a mapping result, and performing guided optimization on the mapping result to determine a mapping image corresponding to the second image. According to the technical scheme, the accuracy of image color mapping and the image quality can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image processing method, an image processing device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In the RGB image and NIR (Near Infrared, near-infrared) image fusion algorithm, it is necessary to perform feature point matching on the dual-camera images, and then perform image alignment and fusion. In the feature point matching process, due to the imaging characteristics of the near-infrared image, the feature descriptors at the same position will be quite different, so the image needs to be mapped first to make the RGB image and the near-infrared image more similar. [0003] In related technologies, a histogram matching method is generally used to perform one-to-one mapping for all pixels. Specifically, the distribution statistics of each pixel value are carried out, and the mapping relationship is calcula...
