Abstract: The traditional Sobel algorithm has some problems in image edge detection, such as sensitivity to noise and poor adaptability to fixed thresholds. In this paper, an improved Sobel algorithm ...

Download the Haar cascade XML file for face detection (e.g., haarcascade_frontalcatface.xml) and place it in the same directory as the script. The webcam will open, and the script will start detecting ...

Abstract: Monitoring mental states is essential for understanding physiological and neurological health, offering insights that enhance diagnostics and therapy. However, current systems are often ...

This includes 4 edge detection methods: Sobel, Prewitt, Laplace and Canny built using algorithms. The report contains the results of methods and comparisons.
