OpenCV Laboratory

Application for rapid prototyping and testing algorithms of computer vision.

Specification

The main advantages of the application are: convenient and elastic node system, quick parameter change using sliders and switches, immediate visualization of the result, easy and continuous code execution, integrated image preview system and integrated code editor, the ability to enter your own code, fast writing/reading including images, codes and description, easy tutorials and ready-made templates.

The application was created on the basis of proven engines: Python, OpenCV, Blender.
