AI Virtual Mouse OpenCV Python | OpenCV Projects | Mr Programmer3 min read

Hey Programmer, In this Post we will be Creating a Virtual Mouse, which Uses Gestures to Control your Mouse. For this Project we will be Using a Python Module Called OpenCV. It is Most Commonly Used For Computer Vision Projects.

Video Tutorial:

OpenCV

OpenCV is a library of programming functions mainly aimed at real-time computer vision. Originally developed by Intel, it was later supported by Willow Garage then Itseez. The library is cross-platform and free for use under the open-source Apache 2 License.
