FEATURE AMOUNT EXTRACTION DEVICE, IMAGE DETECTION DEVICE, AND CONTROL PROGRAM, AND FEATURE AMOUNT EXTRACTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technology with which an appropriate feature amount can be extracted.;SOLUTION: A feature amount extraction device 13 extracting a feature amount from an image includes an evaluation value acquisition unit 130 and a feature amount acquisition unit 131. The evaluation value acquisition unit 130 takes each of a plurality of pixels included in an image as a target pixel, and determines an evaluation value indicating a relationship between a pixel value of the target pixel and a plurality of peripheral pixel values. The feature amount acquisition unit 131 determines a co-occurrence frequency for the evaluation value determined by the evaluation value acquisition unit 130, and takes the co-occurrence frequency as a feature amount.;COPYRIGHT: (C)2014,JPO&INPIT
