The original image contains two shiny, horizontal objects (welding seams). Let’s try to find only these objects on the image, and skip all other noise.
Just as before (Finding defects on an object) start with a global tresholding (HistDIBThreshold in BiFilter.Dll) with Threshold value = 137.
To be able to use the morphological filters, the image must be transformed into a binary image (DitherFS4 in BiImage.Dll).
The last step is a simple binary closing (BinaryClosing in BiFilter.Dll) with a 3 times 3 full one structuring function.
The final image contains only the objects of interest.
