“Neural Dynamic Image-Based Rendering: Creating Awesome Video Effects with Your Phone’s Camera”

A phone’s camera is great for capturing everyday moments. But when it comes to capturing dynamic scenes, like sweeping the camera around to highlight a dramatic moment, you usually need expensive equipment. But what if you could achieve those effects using just your phone’s camera? That’s where Neural Dynamic Image-Based Rendering (DynIBaR) comes in.

DynIBaR is a new method that generates photorealistic free-viewpoint renderings from a single video of a complex, dynamic scene. It can create video effects like the famous “bullet time” effect, video stabilization, depth of field, and slow motion. This opens up new possibilities for video editing applications.

The great thing is, we’ve released the code for DynIBaR on our project page, so you can try it out for yourself. With DynIBaR, you can freeze time while the camera keeps moving through the scene. It’s a game-changer for capturing and editing videos.

In the past few years, there have been great advancements in computer vision techniques for reconstructing and rendering static scenes. But most videos we capture are of moving objects, which presents a more challenging problem. Standard methods for rendering videos of moving scenes produce blurry, inaccurate results.

DynIBaR solves this problem by using an image-based rendering (IBR) method called IBRNet. IBRNet blends nearby images together to create new views of a scene. To extend IBR to dynamic scenes, DynIBaR takes motion into account. It solves for the motion of every 3D point in the scene and uses the input video frames to render new views. It’s a more efficient approach that avoids storing the entire scene in a giant neural network.

To optimize DynIBaR for a given video, we compare the rendered image to the input frame. This ensures that our representation perfectly reconstructs the video. But since reconstructing a complex, moving scene is a difficult problem, we use other techniques like cross-time rendering to improve the results. We also separate the scene into static and dynamic components for better rendering fidelity.

The results speak for themselves. DynIBaR produces smoother, higher-quality videos with fewer artifacts compared to existing methods. It’s particularly impressive in video stabilization, simultaneous view synthesis and slow motion, and video bokeh. With DynIBaR, you can create stunning videos with your phone’s camera.

So why wait? Give DynIBaR a try and take your videos to the next level. You’ll be amazed at what your phone’s camera can do.

Get started with DynIBaR today and unlock the full potential of your phone’s camera.
