Re: [Algorithms] image map to degree (angle)

[Tom S. <tom...@ya...>]

the image is a Equirectangular
the image is viewed in panorama viewer

is there a way to use interpolation to map x,y to pan,tilt angles

is there any interpolation code I can look at

There is only one angle in a 2D situation... the pan / tilt concept only 
makes sense in a 3D space.

Are you, perhaps, looking for a way to determine the polar coordinates? 
If so, check this out:
