OpenCV installation in windows visual studio
This document provides instructions for setting up OpenCV 2.4.9 on Windows with Visual Studio 2013 for 64-bit systems. It includes steps for configuring project properties for include directories and libraries. Code samples are provided to read from a video camera and display frames, and to read and display an image file. Notes are included for adapting the instructions for 32-bit systems and different OpenCV/Visual Studio versions.

- 2. IMPORTANT NOTES: # InMy System the location of OpenCv2.4.9 is C: and so have used C:opencvbuild # Prefer to extract The OpenCv file into drive C: # This settings is for WINDOWS With 64 Bit Operating system and you have to follow the NOTES for 32Bit System # Have Installed Visual Studio 2013 >>and so in the code ";%OPENCV_DIR%x64vc12bin" and "$(OPENCV_DIR)x64vc12lib" I have used the vc12 # If you have installed Visual Studio 2012 then use vc11.
- 5. Step 5 OPENCV_DIR C:opencvbuild Step 8 ;%OPENCV_DIR%x64vc12bin NOTE: For32Bit (x86) System Replace x64 with x86
- 11. For 32Bit SystemSKIP The STEPS From 11 to 14. NEED NOT CHANGE THE PLATFORM TO x64 LEAVE IT AS WIN32.
- 18. Additional Include Directories $(OPENCV_DIR)include AdditionalLibrary Directories $(OPENCV_DIR)x64vc12lib NOTE: For 32Bit (x86) System Replace x64 with x86
- 22. Depending on theOpencv Version the library names have to be modified in the text given . In the next slide you will see a set of library names like “opencv_gpu249.lib” Here 249 corresponds to the Opencv Version (2.4.9) If you are using Opencv 2.4.5 Then replace 249 with 245
- 23.
- 24. NEED NOT DOTHE STEPS FOR DEBUG only Release is necessary. If you need to build in DEBUG mode then do the steps from 23 to 25
