Hi everyone,

how can I change the window size s of the BinarizeBradley method?

https://reference.aspose.com/net/imaging/aspose.imaging/rastercachedimage/methods/binarizebradley

I want to experiment with smaller / bigger window sizes.

Kind regards,
AllMiku

@AllMiku,

I suggest you to please try using following example code on your end in order to explore the property.

string inputFile = @"D:\examples\input\1dicomEtalon.dicom";
            string outputFile = @"D:\examples\output\bradley.bmp";
            using (DicomImage image = new DicomImage(inputFile))
            {
                image.BinarizeBradley(10);
                image.Save(outputFile, new BmpOptions());
            }

        string inputFile = @"D:\examples\input\1dicomEtalon.dicom";
        string outputFile = @"D:\examples\output\Fixed.bmp";
        using (DicomImage image = new DicomImage(inputFile))
        {
            image.BinarizeFixed(100);
            image.Save(outputFile, new BmpOptions());
        }


        string inputFile = @"D:\examples\input\1dicomEtalon.dicom";
        string outputFile = @"D:\examples\output\otsu.bmp";
        using (DicomImage image = new DicomImage(inputFile))
        {
            image.BinarizeOtsu();
            image.Save(outputFile, new BmpOptions());
        }

@mudassir.fayyaz
thank you for your response!

But I don’t see where I can adjust the window size s of the BinarizeBradley Method? The parameter 10 that you are passing to BinarizeBradley is the brightnessDifference, not the window size s.

The window size s is also mentioned in the docs, but it looks like that it can not be changed?

Kindly,

@AllMiku,

I have observed the requirements and have not been able to completely understand it. Can you please share the detailed requirement in the form of sample image so that we may investigate that to help you further.

My requirement does not involve a sample image. It’s a general question: Is it possible to change the window size s in the BinarizeBradley method?

  1. Go to the Aspose Documentation of the Binarize Bradley Method:
    BinarizeBradley | Aspose.Imaging for .NET API Reference
  2. You can read: “The brightness difference between pixel and the average of an s x s window of pixels centered around this pixel.”
  3. I want to know: can I change the size of this s x s window? If yes, how?
