Hi,
I was wondering which might be the best method (performance-wise) to sharpen real-time video frames (I am using an Android phone for this).
I have: 2x/4x/8x (digitally) zoomed real-time video frames My problem: 4x/8x zoom is pretty blurry I want to: sharpen the zoomed video frames in real-time
One idea is to use a laplacian filter on the zoomed video frames. The question is: is this the best idea performance-wise? What else could I use? Maybe I should smooth the video frames before I use the laplacian filter..
Any thoughts on the topic are appreciated :)!
This is how my images look now (screenshots from a phone):
