AI Technical Summary

Benefits of technology

This patented technology describes an algorithm that solves problems like missing colors caused when capturing images from different sources such as cameras due to differences between spectral sensitivity characteristics across various devices used during imagery capture. It uses two types of networks - one works at both wavelengths while another tries to remove unwanted signals without affecting important parts of the captured scene (such as edges). By doing this, it improves overall picture quality and reduces processing costs associated with acquiring data.

Problems solved by technology

This patented technology describes how different types of cameras work together differently due to their own characteristics such as resolutions or lens filters. However, current methods require manually adjustment and are time-consuming process which makes them difficult to use effectively across multiple models without requiring extensive training data from experts.

Abstract

The embodiment of the invention provides a demosaicing method and device, electronic equipment and a storage medium. The method comprises: obtaining a target RGBIR image; performing first processing on the target RGBIR image by using a first neural network to obtain a target IR image; and/or performing second processing on the target RGBIR image by using a second neural network to obtain a target RGB image, wherein the first processing comprises: eliminating a visible light component in a pixel value corresponding to an IR channel pixel point in the target RGBIR image and predicting a pixel value of a color channel pixel point in an IR channel, and the second processing comprises: eliminating a near-infrared light component in a pixel value corresponding to the color channel pixel point in the target RGBIR image for each color channel, and predicting the pixel values of the pixel points except the pixel points of the color channel in the color channel.
