The Find if Touching Window check box enables the system to determine if blobs that are touching the edge of the search window are found, or not found.
When unchecked, blobs touching the edge of the search window will not be found.
When checked, blobs touching the edge of the search window will be found. Caution: When a blob touching the edge of the search window is found, the part of the blob outside of the search window is not used for the blob calculations. The found blob's characteristics are only based on the portion of the blob within the search window.
When the search window is maximized, then the edge of the field of view is considered the edge of the search window.
