Constant opencv::text::ERGROUPING_ORIENTATION_ANY

pub const ERGROUPING_ORIENTATION_ANY: i32 = 1;

Text grouping method proposed in Gomez13 Gomez14 for grouping arbitrary oriented text. Regions are agglomerated by Single Linkage Clustering in a weighted feature space that combines proximity (x,y coordinates) and similarity measures (color, size, gradient magnitude, stroke width, etc.). SLC provides a dendrogram where each node represents a text group hypothesis. Then the algorithm finds the branches corresponding to text groups by traversing this dendrogram with a stopping rule that combines the output of a rotation invariant text group classifier and a probabilistic measure for hierarchical clustering validity assessment.

Note: This mode is not supported due NFA code removal ( https://github.com/opencv/opencv_contrib/issues/2235 )
