Focus assist?

Hi GPU experts.

I’m looking for some guidance/pointers :-)

Imagine you have a CSI camera into the Jetson TX1 with a lens that has no zoom functionality but the ability to change the focus.

I have seen various implementations ranging from Peaking to “Focus assist filter” like seen here:

Is there any opensource vision/cuda or similar libraries that does something like this?

Is it difficult to implement? does Jetson have any good GPU features that could work for something like this?


opencv or matlab most likely have some methods to determine how sharp or fuzzy a particular image is.


We don’t officially have defocus/refocus sample.

Suppose that you can implement it with some filers and analysis operation.
In VisionWorks, lots of basic vision operations are supported:
