Claim 0:
1. A method of joint denoising and demosaicing using a neural network to generate an output image, the method comprising:
obtaining color filter array (CFA) image data collected by a color filter array; and
performing denoising and demosaicing jointly on the CFA image data using a trained neural network to generate the output image,
wherein the neural network comprises a lightweight U-Net architecture and is trained on a plurality of pairs of training images,
wherein a first image in each respective pair of training images is obtained with a lower International Organization for Standardization (ISO) value than another image in the pair of training images and the first image is processed by an image signal processor (ISP) algorithm, and
wherein a second image in the pair of training images is in a format of CFA image data.
