Outline of Final Research Achievements

We proposed a fast and convenient multispectral imaging system aimed for applications requiring a higher color fidelity, such as tele-medicine and remote sensing. In this period, we developed a new color filter array design, a new compression method for mosaicked image, and a new demosaicking method for recovering loss of spectrum. As a result, the total data amount of the 16-band multispectral image can be suppressed as same as 3-band image, and the recovered image has a potential to be applied to pathological diagnosis.
