Detailed Description

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).
