Settings

The plugin allows you to adjust a set of parameters (detection thresholds, blur type, etc.) that influence the detection level and the type of blur application. These parameters are set with default values, but you can modify them if needed.

Most of the time, you will find that changing settings that affect detection and track is unnecessary, as default values have been chosen to be effective in almost all situations.

However, in certain circumstances, changing the default values, such as the detection threshold, can be useful.

Settings area

Blur strength

This parameter allows you to set the strength of the blur. The higher this value is, the less the blurred object could be recognized. The value ranges from 0 to 1 and is set to 0.2 by default.

The value for this setting may depend on the number of pixels of the object. An object with higher definition (more pixels) will require a higher value.

Be careful, the value of this setting can impact the processing time if you set it too high!

Blur fade

This parameter adjusts the diameter of the blur application. The higher the value, the larger the blurred area will be. The value ranges from 0 to 1 and is set to 0.3 by default.

Candidates Threshold

Each face/plate detection has a confidence score. The higher the score, the more likely the detection is accurate; the lower the score, the more likely it could be a false detection. This threshold allows you to keep (during processing) only the detections with a score above the configured threshold.

The value ranges from 0 to 1 and is set to 0.2 by default.

Candidates Overlap Threshold

This parameter defines the maximum threshold from which two detected areas are treated as two separate objects. If two detections are too close the smaller is deleted.

The value ranges from 0 to 1 and is set to 0.4 by default.

Tracking Overlap Threshold

This parameter defines the maximum threshold between two consecutive detections (between 2 frames) to be treated as the same object. If two detections on two different frames overlap more than the threshold they will be added to the track.

The value ranges from 0 to 1 and is set to 0.5 by default.

Blur all detected faces

This parameter allows you to enable or disable blurring for all faces. By default, all faces are blurred.

Blur all detected license plates

This parameter allows you to enable or disable blurring for all plates. By default, all plates are blurred.
