RasterCachedImageBinarizeBradley Method (Double, Int32)
Binarization of an image using Bradley's adaptive thresholding algorithm using the integral image thresholding

Namespace: Aspose.Imaging
Assembly: Aspose.Imaging (in Aspose.Imaging.dll) Version: 20.06
Syntax
public override void BinarizeBradley(
	double brightnessDifference,
	int windowSize
)

Parameters

brightnessDifference
Type: SystemDouble
The brightness difference between pixel and the average of an s x s window of pixels centered around this pixel.
windowSize
Type: SystemInt32
The size of s x s window of pixels centered around this pixel
Examples
The following example binarizes a raster cached image with Bradley's adaptive thresholding algorithm with the specified window size. Binarized images contain only 2 colors - black and white.
[C#]

string dir = "c:\\temp\\";

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterCachedImage rasterImage = (Aspose.Imaging.RasterCachedImage)image;

    // Binarize the image with a brightness difference of 5.
    // The brightness is a difference between a pixel and the average of an 10 x 10 window of pixels centered around this pixel.
    rasterImage.BinarizeBradley(5, 10);
    rasterImage.Save(dir + "sample.BinarizeBradley5_10x10.png");
}
