	//!
	//!    Class-specific Extremal Regions for Scene Text Detection
	//!    --------------------------------------------------------
	//!
	//!    The scene text detection algorithm described below has been initially proposed by Lukás Neumann &
	//!    Jiri Matas [Neumann11](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_Neumann11). The main idea behind Class-specific Extremal Regions is similar to the MSER
	//!    in that suitable Extremal Regions (ERs) are selected from the whole component tree of the image.
	//!    However, this technique differs from MSER in that selection of suitable ERs is done by a sequential
	//!    classifier trained for character detection, i.e. dropping the stability requirement of MSERs and
	//!    selecting class-specific (not necessarily stable) regions.
	//!
	//!    The component tree of an image is constructed by thresholding by an increasing value step-by-step
	//!    from 0 to 255 and then linking the obtained connected components from successive levels in a
	//!    hierarchy by their inclusion relation:
	//!
	//!    ![image](https://docs.opencv.org/4.10.0/component_tree.png)
	//!
	//!    The component tree may contain a huge number of regions even for a very simple image as shown in
	//!    the previous image. This number can easily reach the order of 1 x 10\^6 regions for an average 1
	//!    Megapixel image. In order to efficiently select suitable regions among all the ERs the algorithm
	//!    make use of a sequential classifier with two differentiated stages.
	//!
	//!    In the first stage incrementally computable descriptors (area, perimeter, bounding box, and Euler's
	//!    number) are computed (in O(1)) for each region r and used as features for a classifier which
	//!    estimates the class-conditional probability p(r|character). Only the ERs which correspond to local
	//!    maximum of the probability p(r|character) are selected (if their probability is above a global limit
	//!    p_min and the difference between local maximum and local minimum is greater than a delta_min
	//!    value).
	//!
	//!    In the second stage, the ERs that passed the first stage are classified into character and
	//!    non-character classes using more informative but also more computationally expensive features. (Hole
	//!    area ratio, convex hull ratio, and the number of outer boundary inflexion points).
	//!
	//!    This ER filtering process is done in different single-channel projections of the input image in
	//!    order to increase the character localization recall.
	//!
	//!    After the ER filtering is done on each input channel, character candidates must be grouped in
	//!    high-level text blocks (i.e. words, text lines, paragraphs, ...). The opencv_text module implements
	//!    two different grouping algorithms: the Exhaustive Search algorithm proposed in [Neumann12](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_Neumann12) for
	//!    grouping horizontally aligned text, and the method proposed by Lluis Gomez and Dimosthenis Karatzas
	//!    in [Gomez13](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_Gomez13) [Gomez14](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_Gomez14) for grouping arbitrary oriented text (see erGrouping).
	//!
	//!    To see the text detector at work, have a look at the textdetection demo:
	//!    <https://github.com/opencv/opencv_contrib/blob/master/modules/text/samples/textdetection.cpp>
