Revision history [back]

I'm posting some images from a simple test. 2 webcams looks at same scene: a flame from a common lighter.

On the left, an image from a Webcam where the IR cut filter (piece of glass on the sensor) has been removed and a visible cut filter (a piece of enveloped photo negative in front of lens) has been installed. On the right, same scene from standard laptop webcam.

The result is same also if the flame is far from the cam.

I think this example is explicative :)

You can search the Internet by "remove IR cut filter webcam" or, if you like raspberrypi, to buy a pi-noir-camera

Solution isn't always only in the algorithms even if to modify the environment is not always feasible and sure isn't a machine learning approach.

enjoy with experiments ;)
