Abstract
A discrimination filtering device includes a filter and a filter having different pass bands, a detection unit, a processing unit, and a result output unit. The detection unit detects an electromagnetic wave from an object that is the target of identification through the filters. The pass band of the filters is designed to be suitable for object discrimination. The processing unit substitutes the output from the detection unit into a discrimination function determined based on the pass band of the filters and the teaching spectrum obtained in advance to infer the group which the object belongs to based on the substituted result.
