Outline of Final Research Achievements

Storing scene reflectance, which independents to environmental light sources, as an image (reflectance estimation) is an important issue for the development of digital archive and medical technology. However, a reflectance estimation technique still has not been established for hyperspectral imaging having high spectral resolution. A major factor is a lack of light intensity when taking an HS image, and it causes sensor noise, focus blur, under-exposure.
To solve these problems, this research established novel multiple image blending methods based on convex optimization and sparse coding techniques.
