| Property | Defined By | ||
|---|---|---|---|
| runsEveryFrame : Boolean [read-only]

Calculate a new threshold. | DrunkHistogramThresholdAdapter | ||

initFromXML(paramsObj:Object):void
Init from a name-value paired object that contains parameters parsed from XML. | DrunkHistogramThresholdAdapter | ||

runsEveryFrame:Boolean [read-only]
Returns false;
DrunkHistogramThresholdAdapter runs only when confidence is low (poor marker detection).
public function get runsEveryFrame():Boolean| speed | property |
speed:NumberThe speed at which the threshold changes during adaptive thresholding. Larger values may increase the speed at which the markers in uneven illumination are detected, but may also result in instability in marker detection. Value must be zero or greater. The default is 0.3. A value of zero will disable adaptive thresholding.
