Method for classifying children and adult bt using head and body height in images

摘要

The present invention relates to a method and apparatus for detecting a pedestrian area from a video image, detecting a head area, calculating a ratio therebetween, and determining whether or not an adult is below a predetermined threshold value. How to identify adults ". The method of distinguishing between a child and an adult using the ratio of the height to the height of the head in the video image proposed by the present invention, Detecting a pedestrian area from a video image as a first rectangular area; Detecting a head area of the detected pedestrian as a second rectangular area; Determining a height ratio of the head area to a height of the pedestrian area as a height ratio of a second rectangle to a height of the first rectangle; And judging that the child is an adult when the height ratio is less than or equal to a predetermined threshold value; According to the present invention, since a pedestrian area is detected from a video image, a head area is detected, a ratio between them is determined, and then it is determined whether an adult is below a predetermined threshold value. .
