<P>PROBLEM TO BE SOLVED: To provide a detection method and a detection device for body that can detect an object of detection in an image precisely in a short time. <P>SOLUTION: In a detection device 10 for body including a learning mechanism 11 which structures a weak discriminator for discriminating an object of detection from a learning image 13, and a determination mechanism 12 which determines whether the object of detection is present within a search range 14 by RealAdaBoost using a discriminator composed of the weak discriminator while setting the search range 14 in an inspection image, the leaning mechanism 11 includes HOG feature quantity calculating means 16 of setting the search range 14 in the learning image and a plurality of sizes of cells 15 determining the size of a local area in the search range 14, and calculating HOG feature quantities A by the cells 15 of the respective sizes by arranging the cells 15 over entirely in the search range 14 while putting the cells 15 partially one over another so as to find HOG feature quantities B of the search range 14, and weak discriminator generation means 17 of selecting HOG feature quantities effective in discriminating the object of detection from the HOG feature quantities B using RealAdaBoost to obtain the weak discriminator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
