Final answer:
The subject related to the development of the drowsy driver alert system is Image Processing. In this case, the video stream processing is analyzed using the eye blink concept through an eye aspect ratio (EAR) and Euclidean distance
Step-by-step explanation:
The subject related to the development of the drowsy driver alert system described in the question is Image Processing.
Image processing involves analyzing and manipulating images to extract useful information.
In this case, the video stream processing is analyzed using the eye blink concept through an eye aspect ratio (EAR) and Euclidean distance of the eye to detect drowsiness in drivers.
