Abstract
(EN)
The present invention is an image processing method in which: the edges occurring in an input image are preserved while noise is reduced and an initial noise-reduced image is generated; iterative calculation on the basis of predefined energy is controlled on the basis of an initial residual component that is calculated from the input image and the initial noise-reduced image; the initial noise-reduced image is separated into a framework component and a residual component using the controlled iterative calculation, and the framework component is generated as an output image.
(FR)
L'invention concerne un procédé de traitement d'image dans lequel : les bords présents dans une image d'entrée sont préservés tandis que le bruit est réduit et une image initiale à bruit réduit est générée ; un calcul itératif sur la base d'une énergie prédéfinie est contrôlé d'après un composant résiduel initial qui est calculé à partir de l'image d'entrée et de l'image initiale à bruit réduit ; l'image initiale à bruit réduit est séparée en un composant cadre et un composant résiduel au moyen du calcul itératif contrôlé, et le composant de cadre est généré en tant qu'image de sortie.

本発明は、入力画像におけるエッジを保存しながらノイズを低減して初期ノイズ除去画像を生成し、前記入力画像と前記初期ノイズ除去画像とから算出される初期残差成分に基づいて、予め定義されたエネルギーに基づく繰り返し演算を制御し、前記制御された繰り返し演算によって、前記初期ノイズ除去画像を骨格成分と残差成分に分離し、前記骨格成分を出力画像として生成する画像処理方法である。
