A set of constraints can be specified, limiting the blobs that are found by the tool (result validation). The constraints apply to each blob, and all must be satisfied for a blob to be considered qualified.

Contour area - Area including any holes

Blob area - Area excluding any holes

Number of holes - Minimum and maximum number of holes to accept the blob

Note: Blob with less holes than the minimum limit values will be removed from the results

Size of hole - A minimum hole area implies that the blob must have a hole; a maximum area does not.

Note:  small holes can be ignored by setting the Hole filter

Intensity - used to remove blobs with an average intensity outside the minimum and maximum values
