This is the default detection workflow for the Hole Picker, suitable for Lacey grids. Its execution GUI comprises 8 steps.

Algorithmic steps

Sobel filtering

Produces and image that enhances the boundaries between holes and carbon.

Boundary dilation

Uses the dilation morphological operator to widen the found boundaries.


Size based roi selection

Thinning of selected points

Workflow GUI

The GUI allows for independent execution of each step. Alternatively, the user can just click on 'run all' (at the right bottom corner of the GUI) to execute all the steps at once. If any viewing GUI is opened, the result of each step will update automatically. When the last step it's computed, the results will be exported to the main Hole Picker GUI.
