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

OpenCV: Hough Line Detection
This tutorial will explain the usage of one very important algorithm in the world of image-processing, the Hough line detection algorithm.

Coding Guides: Creating High-Quality Routines
This tutorial gives important guidelines on how to develop high-quality routines which will make our code easier to maintain and understand.

OpenCV: Canny Edge Detector
In this tutorial you will see how to use the Canny OpenCV function in order to apply the Canny edge detection algorithm on an image.

OpenCV: Laplace Filter
In this tutorial we will see how to apply the Laplace filter in order to detect edges in a given image using existing OpenCV functions.

OpenCV: Sobel Filter
In this tutorial we will see two OpenCV functions which we can use to apply the Sobel and Scharr filters to an image to detect edges.
