This function performes a (slow) normalized cross-correlation.
This function performes a (slow) normalized cross-correlation using the window function environment and comparison of the mask with the underlying image part for each pixel. This may however be faster for very few comparisons.This function performes a (slow) normalized cross-correlation using the window function environment and comparison of the mask with the underlying image part for each pixel. This may however be faster for very few comparisons.
The input pixel type T1
must be a linear space over the window functions' value_type T
, i.e. addition of source values, multiplication with functions' values, and NumericTraits must be defined. The mask's value_type must be an algebraic field, i.e. the arithmetic operations (+, -, *, /) and NumericTraits must be defined.
Declarations:
pass 2D array views:
Usage:
#include <vigra/correlation.hxx>
Namespace: vigra
Preconditions:
The image must be larger than the size of the mask.
