Virtual Drums using OpenCV and Python
This study attempts to create a virtual drum system that can be played using a webcam and a computer system alone. It utilizes the many functions of computer vision aided with the OpenCV library. Image processing techniques such as application of a Gaussian filter and thresholding were used in order to track the user's hand and successfully emulate the drum through tracking of its various movements. The contours extracted from the thresholding techniques are tracked by finding their respective bounding rectangles. The result was a system that could emulate a drum and can be played with the hands through striking the different areas of the drum.
