MedianCommandクラス








メンバ 
その近傍でピクセルの中央カラーに、imageで各々のピクセルのカラーを変更します。これはAverageCommandコマンドに似ていますが、ぼかしエフェクトというよりはノイズ除去に使用されます。

構文
'Declaration
 
Public Class MedianCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As MedianCommand

解説
詳細については、「除去ノイズ」を参照してください。
サンプル

imageの上のMedianCommandを実行します、そして、メジアンフィルタを適用します。
