We aim to achieve a high speed, low cost, and more precise multispectral imaging system by developing both MSFA pattern and demosaicking. --Collaborators: University of Southern California (U.S.), Saitama medical university (Japan) #ref(MSFAandDemosaic.png,nolink,80%) **Design of multispectral fiter array [#o9ba05e2] -We improved the demosaicked multispectral image quality by optimizing both spectral sensitivities and spatial pattern of MSFA. --Yudai Yanagi, Kazuma Shinoda, Madoka Hasegawa, Shigeo Kato, Masahiro Ishikawa, Hideki Komagata, and Naoki Kobayashi, "Optimal transparent wavelength and arrangement for multispectral filter array," IS&T International Symposium on Electronic Imaging, Feb. 2016. --Kazuma Shinoda, Taisuke Hamasaki, Madoka Hasegawa, Shigeo Kato, and Antonio Ortega, "Quality metric for filter arrangement in a multispectral filter array," in Proc. of Picture Coding Symposium (PCS), pp. 149-152, San Jose, USA, Dec. 2013. #ref(MSFA.png,nolink,80%) **Demosaicking of multispectral image [#ec42c20c] -We developed some new algorithms (e.g., Multispectral Local directional interpolation, and the minimization problem of vectorial total variation) for multispectral demosaicking. --Kazuma Shinoda, Taisuke Hamasaki, Maru Kawase, Madoka Hasegawa, and Shigeo Kato, "Demosaicking for multispectral images based on vectorial total variation," Optical Review, 2016. --Shu Ogawa, Kazuma Shinoda, Madoka Hasegawa, Shigeo Kato, Masahiro Ishikawa, Hideki Komagata, and Naoki Kobayashi, "Demosaicking Method for Multispectral Images Based on Spatial Gradient and Inter-channel Correlation," International Symposium on Multispectral Colour Science, May. 2016. --Junya Mizutani, Kazuma Shinoda, Madoka Hasegawa, and Shigeo Kato, "Multispectral demosaicking algorithm based on inter-channel correlation," in Proc. of IEEE Visual Communications and Image Processing (VCIP), pp. 474-477, Nov. 2014. #ref(DVTV.png,nolink,80%) #ref(parameter.png,nolink) **Image compression for mosaicked multispectral image [#z725eee8] -Since the data size of multispectral images is increased after demosaicking, we propose to encode the image before demosaicking. --Kazuma Shinoda, Yuri Murakami, Masahiro Yamaguchi, and Antonio Ortega, “An efficient compression method for one-shot multispectral camera,” in Proc. of Picture Coding Symposium (PCS), pp. 269-272, Krakow, Poland, May 2012. #ref(EBI.png,nolink,80%)
