IMAGE PROCESSING METHOD FOR DETECTING STARLING, IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To detect flying of a herd of starlings to a monitoring target without requiring time and efforts for preparing a data set relating to a shape of starling for mechanical learning and further without requiring a long time for processing. ! SOLUTION: The monitoring target is imaged by using an imaging apparatus (S1), and a motion history image representing a motion history in a time division of a predetermined length as one image is created by using data of captured images obtained by imaging (S2). An image feature item is compared with a selection threshold value set to each of image feature items and in a predetermined case, a time division subjected to processing is selected as a candidate of flying of countless starlings (S3). If a distance between a value of the image feature item regarding the captured image in the time division selected as the candidate and a determination straight line is equal to or less than a determination threshold value, the flying of countless starlings is
