Constructor & Destructor Documentation

cv::FastAdjuster::FastAdjuster ( int  init_thresh = 20,
bool  nonmax = true,
int  min_thresh = 1,
int  max_thresh = 200 
)
Parameters:
init_threshthe initial threshold to start with, default = 20
nonmaxwhether to use non max or not for fast feature detection

Member Function Documentation

virtual void cv::FastAdjuster::tooFew ( int  min,
int  n_detected 
) [virtual]

too few features were detected so, adjust the detector params accordingly

Parameters:
minthe minimum number of desired features
n_detectedthe number previously detected

Implements cv::AdjusterAdapter.

virtual void cv::FastAdjuster::tooMany ( int  max,
int  n_detected 
) [virtual]

too many features were detected so, adjust the detector params accordingly

Parameters:
maxthe maximum number of desired features
n_detectedthe number previously detected

Implements cv::AdjusterAdapter.

virtual bool cv::FastAdjuster::good ( ) const [virtual]

are params maxed out or still valid?

Returns:
false if the parameters can't be adjusted any more

Implements cv::AdjusterAdapter.

virtual Ptr<AdjusterAdapter> cv::FastAdjuster::clone ( ) const [virtual]
