One-shot multispectral camera
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 improved the demosaicked multispectral image quality by optimizing both spectral sensitivities and spatial pattern of MSFA.

Demosaicking of multispectral image
- We developed some new algorithms (e.g., Multispectral Local directional interpolation, and the minimization problem of vectorial total variation) for multispectral demosaicking.

Image compression for mosaicked multispectral image
- Since the data size of multispectral images is increased after demosaicking, we propose to encode the image before demosaicking.
