DISCRIMINATOR GENERATION APPARATUS AND IMAGE DIAGNOSIS SUPPORT APPARATUS

To update a discriminator, perform discriminant basis analysis and mis-discriminant cause analysis, update the discriminator using the analysis results, and create the discriminator capable of discriminating objects in images with high accuracy.SOLUTION: A discriminator generation apparatus is configured to: obtain a target image; extract the feature amount of the target image from the target image using a discriminator; discriminate the target image from the feature amount using the discriminator to determine a value of the discriminant; determine a discriminant basis using the feature amount and the value of the discriminant; determine an area to be improved using the discriminant basis and a teacher image; and update the discriminator based on the area to be improved.SELECTED DRAWING: Figure 1 【課題】識別器の更新、識別根拠解析および誤識別原因の分析を行い、その分析結果を用いて識別器を更新し、画像内の物体を高精度に識別可能な識別器の作成を実現する。【解決手段】識別器作成装置は、対象画像を取得し、識別器を用いて対象画像から対象画像の特徴量を抽出し、識別器を用いて特徴量から対象画像を識別して識別値を決定し、特徴量と識別値を用いて識別根拠を決定し、識別根拠と教師画像を用いて改善箇所を決定し、改善箇所に基づき前記識別器を更新する。【選択図】図１
