Abstract†

• We propose a new design method for multispectral filter array based on RGB color filter array. We aim to achieve a high speed, low cost, and more precise multispectral imaging system by developing both MSFA pattern and demosaicking.

Design of multispectral fiter array†

• We improve the demosaicked multispectral image quality by optimizing both spectral sensitivities and spatial pattern of MSFA.

Demosaicking of multispectral image†

• We develop a new algorithm for multispectral demosaicking, e.g., Multispectral Local directional interpolation, and minimization problem of vectorial total variation.

Image compression for mosaicked multispectral image†

• Since the data size of multispectral images increases after demosaicking, we propose a new compression method for mosaicked multispectral images.
