Virtual Keyboard 2 – Gaze controlled keyboard with Python and Opencv p.6
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…
Virtual Keyboard – Gaze controlled keyboard with Python and Opencv p.5
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…
Eye Gaze detection 2 – Gaze controlled keyboard with Python and Opencv p.4
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…
Eye Gaze detection 1 – Gaze controlled keyboard with Python and Opencv p.3
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…
Eye Blinking detection – Gaze controlled keyboard with Python and Opencv p.2
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…
Eye detection – Gaze controlled keyboard with Python and Opencv p.1
In this new video series “Gaze controlled keyboard” we’re going to create and app to control the keyboard trough our eyes using Python with Opencv, completely from scratch. The goal of such app is to write without using the hands. Such applications are really important…
Eye motion tracking – Opencv with Python
We’re going to learn in this tutorial how to track the movement of the eye using Opencv and Python. Studying the eye Before getting into details about image processing, let’s study a bit the eye and let’s think what are the possible solutions to do…
Real time shape detection – Opencv with Python 3
In this video tutorial we’re going to see how to detect shapes of geometric figures (like rectangles, triangles and circles) in a live video. We can detect shapes in real time in this three simple steps: Detect the objects, removing the background. Find the contours…

We’re going to see in this video how to create a cartoon effect. A cartoon has 2 important charateristics: Really clear edges Homogeneus colours Starting from an original image taken with a camera we’re going to give to it a cartoon effect keeping in mind…
Face detection using Haar Cascades – OpenCV 3.4 with python 3 Tutorial 37
You will learn in this video how to detect Faces using the Haar Cascades object detection method. Source code: import cv2 import numpy as np def nothing(x): pass cap = cv2.VideoCapture(0) face_cascade = cv2.CascadeClassifier(“haarcascade_frontalface_default.xml”) cv2.namedWindow(“Frame”) cv2.createTrackbar(“Neighbours”, “Frame”, 5, 20, nothing) while True: _, frame…
Simple shape detection – Opencv with Python 3
We’ll se in this video how to perform a simple shape detection. Starting from an image with a few shapes, we’ll be able to detect exactly each shape (rectangle, circle, pentagon, etc.) and the position. As first thing we need to import the libraries, then…
