Title:
SYSTEMS AND METHODS FOR MULTISPECTRAL IMAGE DEMOSAICKING USING DEEP PANCHROMATIC IMAGE GUIDED RESIDUAL INTERPOLATION
Document Type and Number:
WIPO Patent Application WO/2021/003594
Kind Code:
A1
Abstract:
Systems and methods for multispectral image demosaicking using deep panchromatic image guided residual interpolation are disclosed. ResNet-based deep learning models are disclosed to reconstruct the full-resolution panchromatic image from multispectral filter array (MSFA) mosaic image. Reconstructed deep panchromatic image (DPI) is deployed as the guide to recover the full-resolution multispectral image using a two-pass guided residual interpolation methodology. Experiment results demonstrate that the disclosed methods outperform some state-of-the-art conventional and deep learning demosaicking methods both qualitatively and quantitatively.
