PROBLEM TO BE SOLVED: To provide a method of measuring an alopecia advance level for understanding the advance level of alopecia accurately through a mathematical algorithm.SOLUTION: The method of measuring the alopecia advance level includes: a step S10 of detecting the number of hairs based on a video on which a hair condition of a normal site is recorded； a step S20 of calculating the average thickness of the hairs based on the video on which the hair condition of the normal site is recorded； a step S30 of detecting the number of hairs based on a video on which a hair condition of an alopecia site is recorded； a step S40 of calculating the average thickness of the hairs based on the video on which the hair condition of the alopecia site is recorded； and a step S50 of measuring the alopecia advance level base on the number and average thickness of the hairs in the normal site and the number and average thickness of the hairs in the alopecia site.COPYRIGHT: (C)2013,JPO&INPIT【課題】数学的アルゴリズムを通して脱毛の進行程度を正確に把握するための脱毛進行程度の測定方法を提供する。【解決手段】正常部位の毛髪状態を撮影した映像に基づいて毛髪数を検出するステップＳ１０と、正常部位の毛髪状態を撮影した映像に基づいて毛髪の平均太さを算出するステップＳ２０、及び、脱毛部位の毛髪状態を撮影した映像に基づいて毛髪数を検出するステップＳ３０と、脱毛部位の毛髪状態を撮影した映像に基づいて毛髪の平均太さを算出するステップＳ４０と、正常部位の毛髪数と毛髪の平均太さ、脱毛部位の毛髪数と毛髪の平均太さとに基づいて脱毛部位の脱毛進行程度を測定するステップＳ５０を含む脱毛進行程度の測定方法。【選択図】図１
