DetectText
==========

Detect text with stroke width transform.

Dependencies: OpenCV, boost (only for text detection, not raw SWT).

To compile:
g++ -o DetectText TextDetection.cpp FeaturesMain.cpp -lopencv_core -lopencv_highgui -lopencv_imgproc -I/path/to/current/directory
where /path/to/current/directory is replaced with the absolute path to the current directory.

g++ -o swt_opencv SWT.cpp -lopencv_core -lopencv_highgui -lopencv_imgproc -I/Users/jaderberg/Desktop/DetectText -I/opt/local/include -L/opt/local/lib

To run:
./TextDetection input_file output_file dark_on_light
where dark_on_light is 1 or 0, indicating whether the text is darker or lighter than the background.
