opencv_text: src/erfilter.cpp: replaced bit and/or with their logical counterparts
...
Variables p2-p9 are booleans, so combination of logical negation
and use of bit and/or operations in lines 2823 and 2824 results
in the following warning from gcc:
warning: suggest parentheses around operand of ‘!’ or change ‘&’
to ‘&&’ or ‘!’ to ‘~’ [-Wparentheses]

Overload the run() method in BaseOCR class in order to adapt to different classifier callbacks. The original run() method accepts only one Mat input image, this is expected to be a binarzed image with black and white text and works both with the OCRTesseract class and the OCRHMMDecoder class when the character classifier callback works with binary images (e.g. NM). The new run() method accepts two Mat input parameters. One for the gray scale (or color) source image and the other for a binary mask where each connected component corresponds to a pre-segmented character in the input image. This way the OCRHMMDecoder is able to work with character classifiers that operate in grey scale (or color) images (e.g. a CNN).

Fix for Bug #3633 : do away with "quads [2][3] = 255;" The four lowest bits in each quads[i][j] correspond to the 2x2 binary patterns Q_1, Q_2, Q_3 in the NM paper [1] (see in page 4 at the end of first column). Q_1 and Q_2 have four patterns, while Q_3 has only two.
