METHOD FOR ANALYZING MULTIPLE CONTOURS INCLUDED IN IMAGE, SYSTEM FOR ANALYZING MULTIPLE CONTOURS INCLUDED IN IMAGE, AND PROGRAM FOR ANALYZING MULTIPLE CONTOURS INCLUDED IN IMAGE

To provide a method capable of evaluating a feature amount of multiple contours included in an image.SOLUTION: A method for analyzing multiple contours included in an image includes: calculating variation coefficients of a maximum diameter and diameters of multiple contours included in a first area including one side of the image; setting the center of a width of the first area in a vertical direction with respect to the one side as the center of the first area in the case that the variation coefficients of the diameters of the multiple contours included in the first area exist within a prescribed range; making the width of the first area narrow until the variation coefficients of the diameters are within the prescribed range, and then, setting the center of the width of the first area as the center of the first area in the case that the variation coefficients of the diameters are larger than the prescribed range; and making the width of the first area wide until the variation coefficients of the diameters are within the prescribed range, and then, setting the center of the width of the first area as the center of the first area in the case that the variation coefficients of the diameters are smaller than the prescribed range.SELECTED DRAWING: Figure 21 【課題】画像に含まれる複数の輪郭の特徴量を評価可能な方法を提供する。【解決手段】画像の一辺を含む１番目領域に含まれる複数の輪郭の最大径及び径の変動係数を算出し、１番目領域に含まれる複数の輪郭の径の変動係数が所定の範囲内にある場合、一辺に対して垂直方向における１番目領域の幅の中央を、１番目領域の中心とし、径の変動係数が所定の範囲より大きい場合、径の変動係数が所定の範囲内になるまで１番目領域の幅を狭くしてから、１番目領域の幅の中央を、１番目領域の中心とし、径の変動係数が所定の範囲より小さい場合、径の変動係数が所定の範囲内になるまで１番目領域の幅を広げてから、１番目領域の幅の中央を、１番目領域の中心とすることを含む、画像に含まれる複数の輪郭の分析方法。【選択図】図２１
