They look nice, thank you for sharing! It seems like the input images that you used are paintings. I am not sure how well our depth estimation would work on those, definitely something to try out.

It takes two to three seconds to process the input image and can subsequently synthesize each frame in the output video in real time. This makes it possible for the user to adjust the camera path and see the result in real time. Feel free t

I am confused, a quote from Wikipedia: "The Ken Burns effect is a type of panning and zooming effect used in video production from still imagery." Our framework takes a single still image and animates it via panning and zooming wh

I would like to add that our method estimates the scene in full 3D space. Have a look at the additional results, there are a few results that exemplify this when the geometry is a little more complex: http://sniklaus.com/pap

Thank you both for the pointers! Our research on the 3D Ken Burns effect could be used to automate this, but the quality is still a little spotty. Some results look great, some have obvious artifacts. An automated deployment would thus eith

Estimating the scene geometry from a single image is highly challenging and remains an unsolved problem. As such, you can find subtle artifacts like this in most of the results. The artifact that you are referring to stems from a geometry a

Thank you for your feedback! I highly value the opinion of working professionals like you and am taking notes. :)

We were doing a lot of reading to better understand video producers an their usage of the Ken Burns effect. We are ultimately still research scientists with no hands-on video-production experience but we made sure to do our homework. :)

I did not mean to shoot you down or anything, I in fact greatly appreciate your feedback! I unfortunately do not have a television / movie producer background but wish to learn more to better understand and support the workflow of prof

The examples in the video were automatically generated without user feedback. It is actually also possible to manually specify the camera path in order to achieve the effect that you are expecting, for more information feel free to have a l

Those look nice! The premise of the project was to only use a single image as an input in order to be applicable to existing footage. Without this constraint, more stunning effects like the portrait-video parallax become possible. I am sure

I was watching a lot of tutorials like that when I started working on the project. The shown results were created fully automatically, one can optionally refine the camera path though. You can find more information on that in the video on m

Thank you for you kind words! I moved away from having separate websites for each project and am currently trying to bring all my projects to my personal website. I just added the Mini Chess game last night, which used to be an Android app.

I am planning to release the code as well as the dataset but have yet to get approval to do so. If the work is done by an intern, then Adobe is usually fairly open in terms of sharing the work.

If you give up having clean code, you can even fit a raytracer on a business card: http://fabiensanglard.net/rayTracing_back_of_business_card/

Thank you for your kind words. I borrowed the idea from a previous project in which curious students could evaluate the computational performance of their various implementation using a similar plot: https://github.com/snikl

I initially wrote the raytracer in more idiomatic way. However, I wanted to show my students a side-by-side comparison, demonstrating that the program logic is pretty much the same. Take it as you will, I understand your critique though.

I unfortunately had a bug in my code that I just fixed. It should work now, unless you encounter the bug that has been discussed here: https://github.com/mrdoob/three.js/issues/9716

Thank you for your evaluation! It should have been dblDenominator instead of dblDiscriminant and I fixed it accordingly. However, this change does not seem to significantly affect performance.
