Hello everybody!

I would like to know if there is a filter that I could apply in this image to clean all small black pixels.
I need to leave in the image only the horizontal black line.

Something like "clean all [color] objects (group of pixels) with less than [n] pixels".


Tks

Hi,

You can use TImageEnProc.RemoveIsolatedPixels:

// removes single isolated pixels (black pixels)
ImageEnView1.Proc.RemoveIsolatedPixels(0, 1);

// removes groups of two isolated pixels (black pixels)
ImageEnView1.Proc.RemoveIsolatedPixels(0, 2);
