| Research Abstract |
A spectral image include huge volume of data. Multi-variable analysis is usually used to extract important information in the image. On the contrary in the proposed system, important spectroscopic information in the images which we want to investigate is taken in advance in a learning phase and installed in a system as optimized filters. Filter optimization by self-organized map is discussed. Three proto-types of broad-band filtering systems to implement optimize filter functions which include liquid-crystal devises and optical components were constructed. Experimental results of spectral reconstruction from four filterer images by proposed system were compared with measured result by conventional method. A new intelligent eye which is sensitive to spectral characteristics of an object will be expected.
