Wolf's Binarization implementations.
| mln::trait::ch_value< I , bool >::ret scribo::binarization::wolf | ( | const Image< I > & | input, |
| unsigned | window_size, | ||
| double | K | ||
| ) |
Convert an image into a binary image.
| [in] | input | An image. |
| [in] | window_size | The window size. |
| [in] | K | Wolf's formulae constant. |
This implementation is based on article "Text Localization, Enhancement and Binarization in Multimedia Documents", Christian Wolf, Jean-Michel Jolion, Françoise Chassaing, ICPR 2002.
| mln::trait::ch_value< I , bool >::ret scribo::binarization::wolf | ( | const Image< I > & | input, |
| unsigned | window_size | ||
| ) |
Convert an image into a binary image.
Wolf's formulae constant K is set to 0.34.
| [in] | input | An image. |
| [in] | window_size | The window size. |
| mln::trait::ch_value< I , bool >::ret scribo::binarization::wolf | ( | const Image< I > & | input | ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. The window size is set to 11.
| mln::trait::ch_value< I , bool >::ret scribo::binarization::wolf_fast | ( | const Image< I > & | input, |
| unsigned | window_size, | ||
| double | K | ||
| ) |
Convert an image into a binary image.
| [in] | input | An image. |
| [in] | window_size | The window size. |
| [in] | K | Wolf's formulae constant. |
This implementation is based on article "Text Localization, Enhancement and Binarization in Multimedia Documents", Christian Wolf, Jean-Michel Jolion, Françoise Chassaing, ICPR 2002.
This implementation gives an approximation of the results. It is faster than the original implementation thanks to the use of integral images.
