Open Cv Mat Starting Point

I am using chain code as a feature extraction techniques.

Open cv mat starting point.

In this tutorial you will learn how you can process images in python using the opencv library. However i have seen in some research papers that chain code can be made to be starting point invariant. The chain code is highly dependent on the starting point to reduce this dependency we regard the code as a circular number with n numerals. Automatic license number plate recognition anpr with python.

In the end you will have a nice starting point where you use this code base to build upon to create your own librealsense opencv applications. Z a and z b and s is a scaling factor and phi is angle rotation and alpha is starting point factor adjustement. It s used to process images videos and even live streams but in this tutorial we will process images only as a first step.

This tutorial and code sample shows how to do this based on the ubuntu operating system. Number of points in out contour. I have been able to extract chain code of the required object. Before getting started let s install opencv.
