Android Camera2 Image Processing: What is Geometric Correction?

Question

On this page, there is a picture of the camera pipeline (Figure 2). It says, there are eight stages during Image Processing. I found the stages with corresponding names in the CameraMetadata, except for one stage:

Geometric Correction

I have googled for it, but found no information in relation to Android... So what does it do in Android? And how can I access/configure it?

Your search didn't find this? https://en.wikipedia.org/wiki/Image_geometry_correction — Morrison Chang, Sep 09 '15 at 14:14
I see that I did not specify the question correctly. I meant: What does it do in Android? And how to implement it? But thank you nevertheless for the link^^ — Budel, Sep 11 '15 at 07:38
From your original link: "Please note, some image processing blocks shown in the diagram above are not well-defined in the initial release.". My guess is that its for lens geometry correction which would be device/camera specific. This link has some sample pictures at bottom http://graphics.stanford.edu/~dzorin/perception/sig95/ for correcting a wide-angle lens. — Morrison Chang, Sep 11 '15 at 14:39

Geometric correction didn't make it into the initial release of the camera2 API, but not all the diagrams were updated accordingly.

How do you know? Do you have a source for that? – Budel Sep 21 '15 at 06:13

I wrote most of the API. – Eddy Talvala Sep 22 '15 at 21:12
