Re: Neural nets
This can work but it's not as easy as you may think. You need a big, complex network and LOTS of training data if you want to get anything resembling real IR output. Basically your network must estimate the object boundaries, object type, object context and environment conditions to give you meaningful IR results. Those tasks in isolation are currently in the realm of the possible, but in combination I'm not convinced at all.
To focus the thoughts: a visible light pedestrian detection network (e.g. faster R-CNN) has hundreds of millions of coefficients, and researchers still put IR cameras in tandem with it because there is information in the IR that is simply too hard to infer from the visible light image.
