Struct opencv::xfeatures2d::TBMR

pub struct TBMR { /* private fields */ }

Class implementing the Tree Based Morse Regions (TBMR) as described in Najman2014 extended with scaled extraction ability.

Parameters

• min_area: prune areas smaller than minArea
• max_area_relative: prune areas bigger than maxArea = max_area_relative * input_image_size
• scale_factor: scale factor for scaled extraction.
• n_scales: number of applications of the scale factor (octaves).

Note: This algorithm is based on Component Tree (Min/Max) as well as MSER but uses a Morse-theory approach to extract features.

Features are ellipses (similar to MSER, however a MSER feature can never be a TBMR feature and vice versa).
