Abstract
【解決手段】爪甲色素線条のディジタルカラー画像内における各画素のRGBパラメータ値を、それら3つを成分とする3次元ベクトルとみなして、3次元ベクトルのRGB空間における緯度変数と経度変数を求め、緯度変数と経度変数に基づいて規定される点の分布から鑑別指標を求め、鑑別指標を閾値で区別して爪甲色素線条の悪性と良性を鑑別するようにした。また、点の分布を表示して爪甲色素線条の悪性度の可視化を可能にした。
【選択図】図2
Description
爪部初期メラノーマ6例、爪部良性母斑25例について、本手法を適用した。図3にディジタルカラーダーモスコープ画像を示す。図3(a)が初期メラノーマで、(b)が良性母斑である。
2 黒色腫
3 ディジタルカラーダーモスコープ
4 CCDカメラ
