Setup Auto Square Finder using example targets¶

Square Finder is a blob finder and then filtered by blob stats such as size, mean and stand deviation from the mean values in the blob.

Step A is to find all possible square with a generous settings. These settings should be fairly stable if the same scope/camera pair, magnification is used. Make sure Finder Blob size covers a wide range of square opening.

Step B involves the user select a few example targets that would cover the range of blob stats we want it to keep.

Step C samples the valid targets. If you want the targets to evenly distributed in the stats size range chosen by the exemplars, Use multiple target group. For example, if you choose 2 groups, it sorts all targets and then separate the smaller half and larger half. The random sampling only applies to within the group.

The example targets will always be included in the final sampled targets unless some targets are already chosen in that blob previously.
