Here there are several Jupyter Notebooks I use to play with OpenCV in Python 

All these notebooks are mean to be use with their own directory of Pictures.
Below are the mappings between Notebooks and Picture data


1.- Arrow Head Identification/Tracking tutorial

`Head_Tracking_Pablo_style.ipynb`  
							
This code uses data:
`pictures_ArrowHead`



2.- Optical Flow tutorial

`Optical_Flow_Interspecifics_Saturns.ipynb`
					
This code uses data:		
`pictures_Saturns`



3.- Arrow Heads moving tracking

`Tracking_ArrowHeads.ipynb`		
	
This code uses data:
`pictures_Arrowheads_Moving`
