  1. OpenCV

  2. A software cum library used to implement GPU based operations using programming interface • Supports a wide variety of programming languages like C++, Java, Python etc. • Supports lots of algorithms in Computer Vision and Machine Learning. • Available on different platforms like Windows, Linux, OS X, Android, iOS, etc.

  3. Fun Facts • Stands for Open Computer Vision. (Yes, it is Open Source ! ) • Started in Intel by Gary Bradsky, in 1999. • Released in 2000, when VadimPisarevsky joined Bradsky to head the Russian software OpenCV team. • 2005, Stanley, the self-driven vehicle that won the DARPA Grand challenge, used OpenCV. • OpenCV mentored GSoC 2013, to make tutorials for OpenCV-Python!!

  4. Sister Libraries NumPy Matplotlib SciPy

  5. INSTALLATION. . . . (PITA)

  6. DOWNLOAD UNZIP COPY THE APPROPRIATE BIN FILE TO YOUR P-L BIN FOLDER IMPORT/INCLUDE CV2 TEST SOME SAMPLE CODES LIKE IMREAD, IMSHOW, IMWRITE. IF IT WORKS, BE AS HAPPY AS YOU CAN. IF IT DOESN’T, TRY WITH A DIFFERENT VERSION. IF IT STILL DOESN’T WORK, CURSE YOUR LUCK.

  7. Trust me, my entire summer was spent trying to just RUN OpenCV on my machine. • Statistics: • OpenCV worked after… • 3 downloads of the same zip file from the same webpage, • installing and reinstalling the same downloaded file 7 times. • praying to god for 2 continuous days • changing my python interpreter version 2 times • God knows why but some website suggested Visual Studio to build it. I still tried it, because there was nothing else to do. • Finally, I had to use an age old version of opencv and an earlier version of python.. • IT WORKED!!
