Detailed Description

template<typename T>
class mimas::canny_tool< T >

Canny edge extraction tool.

Algorithms and inspiration from TINA. canny_tool is an operator which is used to extract edge strings from input images. Edge extraction method is based upon Canny's algorithm and includes Canny's post processing methods. Found edges are grouped into continuous strings. This class is a template class because it must operator on a template class (the input image).

There are some tutorials about the Canny edge detection technique here:
