OpenCV: Contour Bounding Box
In this tutorial we will see how to draw a bounding box around objects using their contours. We will see several OpenCV functions doing this.

OpenCV: Contour Detection
In this tutorial we will see how to use contour detection algorithm and one OpenCV function to detect contours in a given image.

OpenCV: Shi-Tomasi Corner Detection
In this tutorial we will get familiar with an improved version of the Harris corner detection algorithm – the Shi-Tomasi corner detection.

OpenCV: Harris Corner Detection
In this tutorial we will see how to use the Harris corner detection algorithm, implemented in OpenCV in order to detect corners in the image.

OpenCV: Hough Circle Detection
In this tutorial we will see how to apply the Hough circle detection OpenCV functionality in order to detect circles in a given image.
