C# 클래스 Accord.Imaging.Filters.PointedMeanFloodFill

Flood filling with mean color starting from specified point.

The filter performs image's area filling (4 directional) starting from the specified point. It fills the area of the pointed color, but also fills other colors, which are similar to the pointed within specified tolerance. The area is filled using its mean color.

The filter is similar to PointedColorFloodFill filter, but instead of filling the are with specified color, it fills the area with its mean color. This means that this is a two pass filter - first pass is to calculate the mean value and the second pass is to fill the area. Unlike to PointedColorFloodFill filter, this filter has nothing to do in the case if zero tolerance is specified.

The filter accepts 8 bpp grayscale images and 24 bpp color images for processing.

Sample usage:

// create filter PointedMeanFloodFill filter = new PointedMeanFloodFill( ); // configre the filter filter.Tolerance = Color.FromArgb( 150, 92, 92 ); filter.StartingPoint = new IntPoint( 150, 100 ); // apply the filter filter.ApplyInPlace( image );
