A Human Detection Method Using infrared images

Abstract

 Firstly ,we construct an image dictionary as the reference 
from many images of walking persons toward an infrared camera.
 Secondly,an output image is extracted by overlapping the image 
dictionary and an input image.
 Finally,a ratio of the total amount of the gray level of the
input image to that of the output image is calculated.
 Then we can distinguish a person from other object using 
the ratio.
