Abstract
Description
・「三次元形状顔画像」とは、たるみの評価の対象である人の顔の三次元形状を表す画像のことをいう。
・「水平位」とは、顔の正中線を重力の方向に対して直角に静止させた状態のことをいう。
・「垂直位」とは、顔の正中線を重力の方向に対して平行に静止させた状態のことをいう。
・「視感スコア(視感評価、Sssとも呼ぶ)」とは、たるみの視感による評価を数値化したものである。非特許文献1にあるようにたるみの評価の対象である人の顔が、基準写真1~5のどれに最も近いか判定者の判定により視感スコアが算出される。例えば、視感スコアは、たるみの評価の対象である人の顔が垂直位(つまり、顔の正中線を重力の方向に対して平行に静止させた状態)のときの斜め横顔の画像(顔の正面から左右に45度の角度から顔を撮影した画像)から算出される。なお、たるみの評価の対象である人の顔の視感スコアは、視感スコアが判定された斜め横顔の画像を教師データとして機械学習により生成された学習済みモデルを用いて算出されてもよい。視感スコアは、頬上部、頬下部、頬後方の各部位で判定されるが、いずれかを平均することで新たに生成してもよい。Sssは、特に頬上部と頬下部における視感スコアを平均し、頬上下部における見た目のたるみを示す。
図1は、本発明の一実施形態に係る重力ふくらみについて説明するための図である。被験者の顔が水平位であるときの三次元形状顔画像と被験者の顔が垂直位であるときの三次元形状顔画像とを取得し、水平位のときの三次元形状と垂直位のときの三次元形状とを対比すると、図1の破線内の部位では、垂直位のときのほうが体積が大きかった。このように、垂直位のときのほうが体積が大きい部位の両者(つまり、水平位と垂直位)の体積の差分を重力ふくらみ量(VCswelling)とする。
図2は、本発明の一実施形態に係る重力へこみについて説明するための図である。被験者の顔が水平位であるときの三次元形状顔画像と被験者の顔が垂直位であるときの三次元形状顔画像とを取得し、水平位のときの三次元形状と垂直位のときの三次元形状とを対比すると、図2の破線内の部位では、垂直位のときのほうが体積が小さかった。このように、垂直位のときのほうが体積が小さい部位の両者(つまり、水平位と垂直位)の体積の差分を重力へこみ量(VCshrinking)とする。
顔内移動たるみは、頬全域に発生する。一方、頬前後たるみは、部分的(口元)に発生する。
図9を参照しながら説明する顔内移動たるみと視感スコアとの相関Rから、視感スコアに対する顔内移動たるみの寄与率R2(決定係数とも呼ばれる)は、53パーセントである。一方、図9を参照しながら説明する頬前後たるみと視感スコアとの相関Rから、視感スコアに対する頬前後たるみの寄与率R2(決定係数とも呼ばれる)は、頬前後たるみ有りもしくは無しと判定された群において、おのおの9パーセントもしくは0.4パーセントである。なお、視感スコアとは、たるみの視感による評価を数値化したものである。
図10を参照しながら説明する顔内移動たるみと年齢との関係から、顔内移動たるみと年齢とは相関する(相関係数は0.64)。一方、図10を参照しながら説明する頬前後たるみと年齢との関係から、驚くべきことに頬前後たるみと年齢とは相関せず、頬前後たるみは年齢に関わらない個人差により生じると言える。
図9および図10を参照しながら説明する顔内移動たるみと視感スコア、年齢との関係から、視感評価(視感スコア)0.5あたりの顔内移動たるみの体積の変化は、1.3ccであり、この体積の量は加齢14年分を意味する。一方、図9および図10を参照しながら説明する頬前後たるみと視感スコア、年齢との関係から、視感評価(視感スコア)0.5あたりの頬前後たるみの体積の変化は、1.8ccである。この体積の量は頬前後たるみの有無を意味する。なお、視感スコアとは、たるみの視感による評価を数値化したものである。
顔内移動たるみは、顔全体で長期的に緩やかに進行する重力によって発生するたるみである。一方、頬前後たるみは、年齢に関わらず局所的(口元)に重力によって発生するたるみである。
図11は、本発明の一実施形態に係る評価システム1の構成図である。本発明の一実施形態に係る評価システム(たるみタイプとその程度を評価する評価システムともいう)1は、評価装置(たるみタイプとその程度を評価する評価装置ともいう)10と、撮像端末20と、解析端末30と、を含む。評価装置10と解析端末30は、任意のネットワークを介して、データを送受信することができる。以下、それぞれについて説明する。
算出部102は、重力へこみ量(VCshrinking)をx軸とし、重力ふくらみ量(VCswelling)をy軸としたとき、下記の式(1)にあらわされるように反時計回りに45度だけ座標を変換することによって、顔内移動たるみ量(Sf)および頬前後たるみ量(Sc)を算出する。
算出部301は、水平位のときの三次元形状と垂直位のときの三次元形状とを対比し、垂直位のときに体積が大きい部位(図1で説明した部位)の両者(つまり、水平位と垂直位)の体積の差分を重力ふくらみ量(VCswelling)とする。
算出部301は、水平位のときの三次元形状と垂直位のときの三次元形状とを対比し、垂直位のときに体積が小さい部位(図2で説明した部位)の両者(つまり、水平位と垂直位)の体積の差分を重力へこみ量(VCshrinking)とする。
以下、図15~図22を参照しながら、種々のたるみの評価方法について説明する。なお、図15~図22の方法の一部は、人によって実行されてもよい。
具体的には、解析端末30は、水平位のときの三次元形状と垂直位のときの三次元形状とを対比し、垂直位のときに体積が大きい部位(図1で説明した部位)の両者(つまり、水平位と垂直位)の体積の差分を重力ふくらみ量(VCswelling)とする。
具体的には、解析端末30は、水平位のときの三次元形状と垂直位のときの三次元形状とを対比し、垂直位のときに体積が小さい部位(図2で説明した部位)の両者(つまり、水平位と垂直位)の体積の差分を重力へこみ量(VCshrinking)とする。
タイプ(顔内移動たるみ、頬前後たるみ)
タイプ1、(有、無):加齢たるみタイプ
タイプ2、(無、有):部分たるみタイプ
タイプ3、(有、有):たるみ顔タイプ
タイプ4、(無、無):たるみゼロタイプ
顔内移動たるみを対象者の年齢の平均と比較して、(大、中、小)など程度で示してもよい。
タイプ1、(中):たるみ年齢相応タイプ
タイプ2、(小):若く見えるたるみタイプ
タイプ3、(大):老けて見えるたるみタイプなど。
上記のたるみの評価方法において、評価結果(各値やたるみタイプとその程度)とともに、たるみの解決策を出力するようにすることもできる。具体的には、評価装置10の出力部104は、予め定められた、評価結果(各値やたるみタイプとその程度)に応じた解決策を出力する。例えば、評価装置10の出力部104は、顔内移動たるみ量(Sf)の割合が高い場合には、顔内移動たるみを解消する化粧品やサプリメント、マッサージを含む美容施術、トレーニングを推奨し、頬前後たるみ量(Sc)の割合が高い場合には、頬前後たるみを解消する化粧品やサプリメント、マッサージを含む美容施術、トレーニングを推奨する。例えば、評価装置10の出力部104は、顔内移動たるみ量(Sf)と頬前後たるみ量(Sc)に応じた化粧品やサプリメント、マッサージを含む美容施術、トレーニングを推奨する。
上記のたるみタイプとその程度の評価において、視感スコア(Sss)に対するたるみ肌係数(Cs)の寄与率、視感スコア(Sss)に対する顔内移動たるみ量(Sf)の寄与率、視感スコア(Sss)に対する頬前後たるみ量(Sc)の寄与率に基づいて、各因子の評価に重みづけをするようにしてもよい。
本発明の一実施形態では、対象の水平位と垂直位の三次元形状顔画像を反復して取得し、重力ふくらみ量(VCswelling)と、重力へこみ量(VCshrinking)と、顔内移動たるみ量(Sf)と、頬前後たるみ量(Sc)と、のうちの少なくとも1つを、反復して取得された三次元形状顔画像を用いて算出された値の代表値とすることができる。以下、詳細に説明する。
