template<class Input, class Output, class Exact = mlc::final>
class oln::level::threshold< Input, Output, Exact >

Threshold the value of the image.

 {
   oln::image2d<int_u8> in = oln::load(IMG_IN "lena256.pgm");
   int_u8 th    = 127;
   rgb_8 low    = rgb_8(100, 0, 0);
   rgb_8 height = rgb_8(0, 200, 255);

Constructor & Destructor Documentation

template<class Input, class Output, class Exact = mlc::final> oln::level::threshold< Input, Output, Exact >::threshold (  const Input &  threshold, const Output &  min = ntg::type_traits< Output >::min(), const Output &  max = ntg::type_traits< Output >::max() )  [inline]

Threshold any value heigher or equal to this value will return min. min Value returned if the input is smaller than threshold. max Value returned if the input is greater or equal to the threshold. Definition at line 74 of file threshold.hh. : m_threshold(threshold), m_min(min), m_max(max) {}
