Demosaicing module for an image signal processing pipeline

Abstract

A demosaicing module for an image signal processing pipeline comprises a neural network comprising a plurality of branches, each branch comprising a plurality of successively executable convolutional layers, one convolutional layer of each branch being configured to receive a plurality of image planes acquired from a colour filter array, CFA, image sensor, each image plane having a resolution equal to the image sensor, with only one image plane having a non-blank pixel value at any pixel location and with pixel information for each colour plane maintained in a spatial relationship corresponding to the pixel locations for each colour of the colour filter array. The convolutional layers of each branch are configured to combine the image plane information into a demosaiced image plane in a given image space.
