Options — Filters

The Filters tab shows a live preview of the selected camera and lets you tune the basic detection thresholds used by Classic Vision.

Fields

Field	Description
Filter range	0–255. The core detection threshold.
Erosion	0–100. Used to separate touching or slightly overlapping blobs.
Minimal Area	The minimum blob size (in pixels) to count as a detection.
Release Field	0–100. The field where detections are tracked and judged — once a detection leaves this field, it's processed. Shown on the preview as a green rectangle.
Overlap Field	0–100. Only shown when Camera Frame Stackmode (in the page toolbar) is set to Vertical Stack or Horizontal Stack. Shown on the preview as a yellow dashed rectangle.

Select Calibrate to calibrate the filter threshold against what's currently in view.

Live Preview

The live camera image updates as you adjust these sliders, so you can see the effect immediately — use it to confirm the Release Field (and Overlap Field, if visible) covers the area you expect before selecting Save on the Options page.
