An overview of what a pixel is, how a computer understands it and how pixels can be accessed and manipulated using OpenCV
An explanation of how to read, display and save videos using OpenCV with Python and C++
How to scale the pixel’s intensity and make the image brighter and/or darker, how to add watermark and some other cool effects
In this post we will show to generate the most common types of noise and add them to clean images. We will also show how to filter these images using median filter
The hidden mystery behind average and Gaussian filter
In this post we will show how to calculate the horizontal and vertical edges as well as edges in general
How is Thresholding Being Applied In Computer Vision?
Why do people consider the Canny Edge Detector to be the ultimate edge detector?
Learn how to perform line detection in an image, with the help of a technique called Hough transform
Learn why the Circle Hough Transform in an important feature extractor for detection round circle objects in an image
What are the advantages of using frequency-domain versus time-domain representations of a signal?
An implementation of low pass and high pass filter using OpenCV
Learn why the Harris Corner Detector is an incredible mathematical operator that finds (good) features in an image
Let's see what are Eigenvalues and how to interpret them in order to find a good corner
Histogram Equalization is a technique used for modifying the pixel values in an image to improve the contrast by making those intensities more equal across the board
In this post, we will benchmark 5 most popular face detection algorithms
