Build a drowsiness detector application that analyzes a live video stream to identify driver fatigue using Python, Google Colab, and dlib for face region prediction.
Explore Google Colab as a Google cloud platform for running Jupyter notebooks, with free and paid options, to execute the drowsiness detection project in the cloud and across devices.
Understand the project folder structure for drowsiness detection with dlib, including collab notebooks, a prebuilt dlib shape predictor, alarm sounds, utils, a video stream script, resize, and the notebook.
Explore dlib, a modern C++ toolkit for machine learning, offering clustering, image processing, and face detection with landmark prediction in the next session.
Explore the dlib face detector options, compare the hog-based histogram of oriented gradients with a linear SVM to a CNN-based detector, and discuss real-time viability on CPU versus GPU.
Explore the dlib face region predictor that uses 68 facial landmark points to localize regions like the mouth and eyes, enabling image and video processing, object detection, and drowsiness detection.
Learn to import libraries for a drowsiness detection project with dlib, and set up Google Colab and Google Drive to access utils and predictive files.
Load the dlib face regions predictor file from the resource section and store it in a reusable variable. Define the face region coordinates and store them in a dictionary.
Define face region coordinates using 68 landmark points, focusing on left and right regions; store them in an ordered dictionary for easy retrieval in drowsiness detection with DLib.
Compute the eye aspect ratio by combining vertical distances of landmarks and the horizontal distance, using euclidean distances. Average across eyes and compare to a threshold to detect drowsiness.
Load the dlib face detector and facial landmark predictor, configure blink thresholds and a consecutive-frame counter, and enable an alarm when drowsiness patterns emerge, noting thresholds vary by hardware.
Capture facial landmark indexes for the left and right eyes, store them in the face regions order dictionary, and retrieve the coordinates to extract eye details.
Integrate dlib-based drowsiness detection by streaming webcam video, detecting facial landmarks, computing eye aspect ratio, triggering an alarm after five consecutive frames.
If you want to learn the process to detect drowsiness while a person is driving a car with the help of AI then this course is for you.
In this course I will cover, how to use a pre-trained DLib model to detect drowsiness. This is a hands on project where I will teach you the step by step process in building this drowsiness detector using DLib.
This course will walk you through the initial understanding of DLib, About Dlib Face Detector, About Dlib Face Region Predictor, then using the same to detect drowsiness of a person in a live video stream.
I have splitted and segregated the entire course in Tasks below, for ease of understanding of what will be covered.
Task 1 : Project Overview.
Task 2 : Introduction to Google Colab.
Task 3 : Understanding the project folder structure.
Task 4 : What is Dlib
Task 5 About Dlib Face Detector
Task 6 About Dlib Face Region Predictor
Task 7 : Importing the Libraries.
Task 8 : Loading the dlib face regions predictor
Task 9 : Defining the Face region coordinates
Task 10 : Using Euclidean distance to calculate the Eye Aspect Ratio
Task 11 : Loading the face detector and face landmark predictor
Task 12 : Using the face region coordinates to extract the left and right eye details
Task 13 : Defining a method to play the alarm.
Task 14 : Putting it all together.
Almost all the statistics have identified driver drowsiness as a high priority vehicle safety issue. Drowsiness has been estimated to be involved in 10-40 per cent of crashes on motorways. Fall-asleep crashes are very serious in terms of injury severity and more likely to occur in sleep-deprived individuals.
Hence this problem statement has been picked up to see how we can solve this problem to a great extent by build a drowsiness detector.
However please note, that this has been made purely for educational purpose and refrain from using the same in real world scenarios.
In this course we are going to build a drowsiness detector and use the same to detect in live video streams.
