How can I change the detection threshold for acfDetect?

Hello,
I want to change the detection threshold of ACF Detector in order to generate object proposals.
How can I do it?
Thanks.

Hi,
You can change the threshold via the variable opts.cascThr using acfModify. Then you can use acfDetect with the modified classifier

Emmm, I also confused about how to change the threshold.
If using adaBoostApply in the example in the adaBoostTran.m, it seems you can change t in adaBoostApply>t to adjust the threshold.
However, if using acfDemoInria, it seems that the threshold is controlled by struct('cascThr',-1,'cascCal',.01). So, how to change 'cascThr' and 'cascCal', what's the meaning of these two parameters.
