Abstract

The invention provides an image processing method and device, and electronic equipment, and relates to the technical field of image processing, and the method comprises the steps: obtaining a to-be-processed multichannel image; determining a first target image based on the multi-channel image; determining an initial Bayer image and a target IR image based on the first target image; processing thefirst target image through a neural network model to obtain correction items of R channel pixel points and B channel pixel points in the initial Bayer image; and correcting the channel value of the Rchannel pixel point and the channel value of the B channel pixel point in the initial Bayer image according to the correction item to obtain a target Bayer image. According to the method, a neural network model is used for outputting correction items of pixel points of an R channel and a B channel of an initial Bayer image; the correction processing of the initial Bayer image is realized, and thetarget Bayer image with higher accuracy is obtained, so that the technical problem of low accuracy of a recombined image in an image processing method in the prior art is effectively relieved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device and electronic equipment. Background technique [0002] Remosaic refers to a method of transforming the pixel structure through the signal processing module to rearrange the image returned by the image sensor into a Bayer image, which is convenient for the subsequent image processing process. In the prior art, the interpolation method is usually used to implement Remosaic, and the missing pixels are determined by the weighted average of the pixels around the missing pixels. However, the interpolation method does not make full use of the prior information of the natural picture, resulting in the Bayer image obtained by rearrangement. Undesirable phenomena such as false color or jaggies, especially for images collected by RGB-IR (Red Green Blue-Infrared Radiation, red, green, blue infrared) sensors, the information of the IR chann...
