Método para revertir la distorsión con GIMP de fotos hechas con la Mobius Action Cam

[pablo rey]

Eustatic ha probado un método para quitar la distorsión a las imágenes hehas con la Mobius Cam (una mini cámara muy fácil de usar que permite hacer vuelos con cometa y globo sin necesidad del aparataje de la botella protectora).

Public Lab contributor eustatic just posted a new research note entitled 'A Method for distorting Mobius Action Cam imagery in GIMP (FOSS)':

What I want to do

Make Mapknitter maps with infragram and another mobius (so light!)

So Mat suggested a method of distorting graph paper until it looked right.

Chris Fastie has laid out the limitations of infragram maps --the edges need to be cropped

I think GIMP crops edges.

I want to use this because I'm too poor for photoshop, and freedom rules.

My attempt and results

There are two "Lens Distortion" filters in GIMP

Filters -> Distort -> Lens Distortion

"Main" and "Edge"

Here is the original image

Main -40

Main -41 edges +5

Main -42 edges 0

Main -50 edges 0

Questions and next steps

What do people think?

Y yo acab a de añadir un comentario a su post sugeriendo que debemos poder usar este shader de WebGL para deshacer este tipo de distorción en el browser: https://github.com/mattdesl/filmic-gl/blob/master/demos/shaders/lens.frag

Imagino que seria parte de Infragram.org, quizas?

Alguien conoce bien WebGL?
