Hi! Im trying to port this library to android, but it seems that it will be problem with rolling shutter camera. How i can fix it?

I'm afraid that it may be the problem of DSO. DSO’s performance quickly deteriorates with added geometric noise. If you can get the time interval of rolling shutter, I think maybe you can try to modify the project pixel with estimated pose of different time.

I found paper "Digital Video Stabilization and Rolling Shutter Correction using Gyroscopes". I will try to realize that algorythm and apply rolling shutter correction to image before sending it to DSO pipeline

A great idea. I have also found several papers on this. Did you also find an implementation in C++ or another language, I always found implementations in Matlab with m-scripts.
