openCV examples (Python)

A set of functions (useful for CV) implemented using openCV for Python.

Requirements:

• opencv_contrib package (for SIFT,SURF)

Running it:

• python face_track.py <Y/N> , to use HAAR to track faces in frames and dump them into a .json
• python face_track_manual.py <Y/N>, to manually track features (marking them frame-by-frame)
• python Graphs/face_diff.py <input .json>, to see "difference" plots, in case two features were used
• python Graphs/face_track.py <input .json>, to plot faces across frames (correspondences established via sorting)

Note

You may have to run the following commands (if import cv2 throws any errors):

• sudo ldconfig /usr/local/cuda/lib64
• add export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH to .bashrc
