Detailed Description

template<class TInputImage>
class otb::ContinuousMinimumMaximumImageCalculator< TInputImage >

Compute the continuous maximum and the minimum of an image.

To compute the continuous maximum and the minimum of an image, this class uses a simple polynomial interpolation.

First traditional discrete maximum and minimum are found. Then a second order polynomial is fitted between these extrema and their neighboring pixels.

The continuous extrema is assumed to be at the zero of the first order derivative of this polynom.

If we denote $ (x_0, y_0) $ the extrema and $ (x_{-1}, y_{-1}) $ and $ (x_1, y_1) $ its neighbor, the second degree polynom verify the following equations:

\[ y_{-1} = a*x_{-1}^2 + b*x_{-1} +c y_0 = a*x_0^2 + b*x_0 +c y_1 = a*x_1^2 + b*x_1 +c \]

The maximum is at $ -b/2a $ with is $ -\frac{(y_1-y_{-1})}{(2*(y_{-1}+y_1-2*y_0))} $

Remark: image is assumed to be 2 dimensionnal
