A simple OCR using Opencv + Tesseract. Using code from https://github.com/opencv/opencv_contrib/blob/master/modules/text/samples/end_to_end_recognition.cpp.
- Have a window opened and get its title using Spy++, direct method or any other software.
- Start this program, as you type in your window, the program will detect words and output on console as well as highlight on output screen.
Setup Instructions (Windows)
- Install Tesseract (make sure you select 'add to path' in installer.
- Get OpenCV binaries from https://github.com/cesardelgadof/OpenCVBinaries (works with VS2015/2017).
- Create new empty cpp proj, add source file to project.
- Add opencv include dir in
Project Properties > C/C++ > Additional Include Directories.
- Add opencv lib dir in
Project Properties > Linker > General > Additional Library Directories.
- Add opencv lib files:
- Goto opencv lib folder.
- Open cmd, type
dir /b *d.lib > libs.txt(this is for debug mode libs).
- Open libs.txt and copy/paste to
Project Properties > Linker > Input > Additional Dependencies.
- Run in debug mode! (make sure you have a window opened with the title in
- For testing, notepad or any simple text editor with reasonably big font works best.
- It's easier to use prebuilt libraries, building on windows almost always causes issues.
- To build with tesseract APIs (as required here) you need extra libs from tesseract.
