<P>PROBLEM TO BE SOLVED: To accurately distinguish a pedestrian from an artificial structure for extraction on an infrared image. <P>SOLUTION: An average value (average luminance) AVE and a maximum luminance position xCC are computed with respect to a change (integrated luminance) S(I) corresponding to a horizontal position I of an integrated value of luminance values along a vertical direction for every horizontal position I in a horizontal direction in a predetermined object region (mask) OA including an upper part of at least a binarized object OB. When the breadth w of a region where the integrated luminance S(I) is not less than the average value (average luminance) AVE including the maximum luminance position xCC, is larger than a predetermined head width threshold w_TH concerning the breadth of a human head, the binarized object is determined to be the artificial structure having the upper part of the breadth excessively larger than the breadth of the human head. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
