Abstract
A method of demosaicing a digital raw image in the form of a matrix of pixels, each dedicated to a single color among several predetermined colors from color filters, includes obtaining a color digital image of the same resolution as the raw image and in which each pixel results from corresponding pixels in a luminance image and in chrominance images reconstructed from the raw image, transformation of the raw image by applying local convolution kernels to its pixels, taking into account neighboring pixels of different colors, to obtain an image of low frequency coefficients using a low frequency local kernel and images of high frequency coefficients using high frequency local kernels; reconstruction of the luminance image using at least the image of low frequency coefficients; reconstruction of the chrominance images using the images of high frequency coefficients.
