Member Function Documentation

virtual bool vpDetectorBase::detect ( const vpImage< unsigned char > &  I)
pure virtual

Detect objects in an image.

I: Image where to detect objects.
true if one or multiple objects are detected, false otherwise.

Implemented in vpDetectorAprilTag, vpDetectorQRCode, vpDetectorDataMatrixCode, and vpDetectorFace.
