What it does
JavaCV is a code library that makes well-known computer vision tools available to programs written in Java, including Android apps. Computer vision is the field of teaching computers to understand images and video.
It wraps libraries such as OpenCV (image analysis), FFmpeg (video and audio), Tesseract (reading text in images) and drivers for various cameras. It adds helpers for showing images, calibrating cameras and projectors, and finding matching features between pictures.
Ready-made builds are available for Android, iOS, Linux, macOS and Windows.
Who it's for
