Introduction to OpenCV Python Tutorials¶

Getting Started with OpenCV-Python

OpenCV is a huge open-source library for computer vision, machine learning, and image processing.
It can process images and videos to identify objects, faces, or even the handwriting of a human.
OpenCV was started at Intel in 1999 by Gary Bradsky
Currently OpenCV supports a wide variety of programming languages like C++, Python, Java etc
OpenCV is available on different platforms including Windows, Linux, OS X, Android, iOS etc
Computer-Vision is playing a major role in self-driving cars, robotics as well as in photo correction apps.

OpenCV-Python¶

OpenCV-Python is a library of Python bindings designed to solve computer vision problems. OpenCV-Python makes use of Numpy, which is a highly optimized library for numerical operations with a MATLAB-style syntax. All the OpenCV array structures are converted to and from Numpy arrays. This also makes it easier to integrate with other libraries that use Numpy such as SciPy and Matplotlib.

Applications of OpenCV¶

There are lots of applications which are solved using OpenCV, some of them are listed below

face recognition
Automated inspection and surveillance
number of people – count (foot traffic in a mall, etc)
Vehicle counting on highways along with their speeds
Street view image stitching
Video/image search and retrieval
Robot and driver-less car navigation and control
object recognition
Medical image analysis
Movies – 3D structure from motion
TV Channels advertisement recognition

Installing OpenCV From Prebuilt Binaries¶

We will learn to setup OpenCV-Python in your Windows system. Below Python packages are to be downloaded and installed to their default locations.

Python3
Numpy
Matplotlib
opencv-python

pip install opencv-python

Requirement already satisfied: opencv-python in c:\users\karan\appdata\local\programs\python\python36\lib\site-packages (4.0.0.21)
Requirement already satisfied: numpy>=1.11.3 in c:\users\karan\appdata\local\programs\python\python36\lib\site-packages (from opencv-python) (1.18.5)
Note: you may need to restart the kernel to use updated packages.
