title: Blob Filtering in AForge.Net
body: <p>As you know when we use BlobFiltering class in AForge.Net, it uses the black color (exactly RGB(0,0,0)) for the background color and remove blobs.</p>
  
  <p>Is it possible to change the background color?</p>
  
  <p>UPDATE :
  for example for this image this Filtering not worked (i want to remove little areas)</p>
