CVutils

Uses Python with OpenCV in miscellaneous demos of algorithms useful for computer vision.

Note: Line clipping was moved to its own repo.

Install

python -m pip install -e .

draw_flow() given a 2-D complex Numpy array of optical flow flow, draw flow vectors with arrows
draw_hsv() make a colored HSV image corresponding to flow direction and intensity at each point
connectedComponents.py given a binary image morphed and the blobdet from setupblob(), along with img, do connected components analysis
OpticalFlow_Matlab_vs_Python.py using Horn-Schunck optical flow estimation with OpenCV in Python. Not so obvious from the docs, and with notes on how to make this match Matlab's vision.opticalFlowHS method. Install Matlab Engine for Python
