Hi STeven,
when I use the module Blob_Count, the current image will be affected in a way that is not intended nor desired. I will get an additional black border on the left and upper side of the current image.

CubaMadre,
That's actually expected. The module will clear out a 1 pixel border around the image so that it doesn't need to check for the image bounds when doings its analysis. Its a performance thing. If it is causing you problems, use the Resize_Canvas module to resize the image dimension by 2 pixels in each direction and select Preserve with the Center radio button selected and then call the blob_count. That will allow for the border to be zeroed without changing the image.
Note that many modules will do this.
STeven.
