Description

This Blob Common tool finds blobs that are similer in a set of blobs, according to a user defined threshold.  When blobs are determined to be similar they are grouped together into sets.

Using the Blob Common Tool

Drag either the Blob tool or the Blob Filter tool onto the "Blob" portion of the inputs page and select "Blobs" from the dropdown menu.

On the "Blob Compare" page set which attributes should be used to find matching blobs.  If the attribute area, for example, is set to "0" then area will not be a determining factor in finding similar blobs.  If area is set to "1" then area will be a factor.  If area is set to "2" then the area portion will be given double weight in determining similarity.

The "Common" page will list all of the attributs that have been setup on the "Blob Compare" page.  When the tool is run the similarities for all the blobs in the most common set of blobs will be listed on this page for each enabled attribute.

NOTE: the weight icreaded the scrore
NOTE: the report calues are for the last run blob

Parameters

MinCommonCount

sets min number blobs that constitute a set.  If this number is set to 3, then 3 similar blobs must be found before the tool will consider them a common set of blobs.

MaxError

the allowable difference between blobs in a common set.  This number is a typically 0... range.
NOTE this is the score between any blobs and not the scorer between the blob and the average reported below which will be lower

The Sort Attribute

is a dropdown menu that is used to sort the blob sets.  If this is set to area then the blob set that has the greatest area will be sorted first.
