In this lesson, we will analyze a basic but important tool for identifying colors through a mask. We’re going to see in this video how to detect colors through HSV Color space on Opencv with Python. HSV corresponds to:Hue is the colorSaturation is the greynessValue is the brightness Understanding the concepts of balancing these three […]
This is the final tutorial of the project “Gaze controlled keyboard with Python and Opencv”. The code is approximately 300 lines. I added the missing parts to the code, I improved the graphic of the keyboard and I made a few adjustments. I’m not going to do any coding in this tutorial, instead I will […]
In this tutorial we’re going to add sounds to our project. Especially we need a sound to tell us when the letter was pressed, because when we’re blinking to press the letter we can’t look at the screen at the same time. Also we’re adding two other sounds, one to tell as when the left […]
In this tutorial we’re now going to detect when we press a key by we blink our eyes.We don’t need to add almost anything new as we already we have the keyboard, or at least one part, and we already wrote the function to detect the blinking. At the beginning of the script we’re going […]
In the previous tutorial we learn how to create and display a virtual keyboard using opencv. We have now two files, a main.py file where we have the code for detecting the blinking and the gaze of our eyes, and we have a file where we have the code of our visual keyboard. To simplify […]
We will continue in this section with the creation of the Keyboard. We’re going to split the keyboard in two parts, so that we will be able to access each part of the keyboard by looking at some specific direction. For example if we want to access to all the letters that are on the […]
We’re going to learn in this tutorial how to create a virtual keyboard using Opencv with Python. The idea is to display the Keys on the screen and light them up one at time. Once the key we want to press is lighted up, we simply would need to close our eyes and the key […]
We’re going to learn in this tutorial how to detect the gaze, and more specifically to detect if the eyes are looking to the left, the right or the center. To detect the gaze we need first to understand how the eye appears when it’s looking in different directions.I’ve discussed this into details in another […]
We are going to learn in this tutorial how to detect the gaze. Why do we need to detect the gaze? To answer to this question I need to explain to you how I plan to run the app.The idea is to see a keyboard on the screen, light up each key every second or […]
In this second part of the series “Gaze controlled keyboard” we’re going to detect when the Eye is blinking. We’re going to use this function later on to press the selected key on the virtual keyboard just by blinking our eyes. When is the eye blinking? If you think about this question, what possible explanation […]
