<pre>
The confidence threshold we perform filtering on the labels from
frame-level detection. If not set, it is set to 0.4 by default. The valid
range for this threshold is [0.1, 0.9]. Any value set outside of this
range will be clipped.
Note: For best results, follow the default threshold. We will update
the default threshold everytime when we release a new model.

@return The frameConfidenceThreshold.
