Opencv Shape Detection C++

I once wrote a similar OpenCV application [1], but in my case I needed to detect a closed contour and evaluate how close that contour was to being a circle. Computers have helped mankind solve lots of problems and complete lots of difficult tasks. For better accuracy, use binary images. opencv is available on Mac, Windows, Linux. The most popular and probably the simplest way to detect faces using Python is by using the OpenCV package. i didn't find a tutorial for face shape identifying. First, perform a background subtraction. In line 4, we converted the image to grayscale because OpenCV mostly operates in gray scale. 0-dev for Python2 on Windows using CMake and Visual Studio; Cascade Classifiers; Contrast and Brightness in C++; Creating a Video; Display Image OpenCV; Drawing Functions in Java; Drawing Shapes (Line, Circle, , etc) in C++; Edge detection.
