 note = {インパルス性雑音によって劣化した画像を復元する手法の 1 つである荷重メジアンフィルタは，画像に適したフィルタの窓形状と荷重の設計は重要な課題である．その設計の際には多くの場合トレードオフの関係を有する非劣化画素の信号保存性能と劣化画素の雑音除去性能を考慮する必要がある．本論文ではフィルタ設計をこれらの評価基準を同時に考慮しながら最適化を行う多目的最適化問題として定式化し，一度の解探索で信号保存性能を重視したフィルタと雑音除去性能を重視したフィルタが同時に得られる手法を提案する．, Estimation of a suitable window shape and appropriate weights in weighted median filters (WMFs) is one of important problems. In this paper, we propose a new unsupervised design method of WMFs. To recover images from the noise, any filters must preserve original values of non-corruped pixels and simultaneously well estimate the original values of corrupted pixels; however, the preservation quality and the restoration quality often have a trade-off relation. We formulate the design of WMF as a multi-objective optimization problem that treats the preservation performance and the restoration performance as conflict functions. Through the experiments, we show our method obtains a wide variety of filters that have the high preservation performance or the high restoration performance at one search process.},
