cannyfier 0.2.5

Show canny on any part of the screen. Better to use with video

Real Time Video Reader

This project aims to read the video from the computer screen and process it using the Canny edges to detect lines.

Allows to adjust the parameters of the Canny detection in real time through slide vars.

It is advisable to have 2 monitors (one being captured real time and another that is showing the canny edges)

When not having 2 monitors reduce the captured screen so the capture and The canny fit in one screen.
