Blob Border
The Blob Border module is used to identify just the outline of blobs of different colors such that they can be processed as edges by other modules. For instance, if an image is segmented into colored blobs simply by reducing the number of colors used there will be many blobs that touch each other. Applying a circle detection module will assume that only edges are present in the image and will not function correctly unless edges are present. Using the Blob Border module prior to the circle detection module will ensure that the circle module treats each differently colored blobs as an edge.
Instructions
1. Insert the Blob Border module. All blobs will be converted to just their outlines.
