Project Indigo

A good camera is one of the major selling points of any new smartphones and software is the major driver of innovation to achieve great pictures these days. But what if you could just improve your camera by downloading better software?

Computer Vision Reviewer Awards

With the top computer vision conferences now mentioning the top reviewers, I was wondering what the statistics for CVPR / ICCV / ECCV look like. These staristics could, for example, be used to find good candidates for an internship.

Video Denoising

webpage / arXiv

We bridge the the gap between traditional denoising techniques and modern machine learning, allowing us to establish a new state of the art method for video denoising that is not only robust and fast but also controllable.

Clean Machine

webpage / video

Imagine being the videographer at a wedding, and the photographer is extensively using their flash. This will lead to overexposed frames in the video which severely degrades the captured footage, but Clean Machine is here to help.

Image Denoising

We have recently introduced a new denosier in Lightroom that was pioneered by Michael Gharbi before he left Adobe to found a startup. Since then, Zhihao Xia and I have been the research leads behind this technology.

3D Mockup

A common task for creative professionals is to mockup a design onto an object. This can challenging though, imagine putting a logo onto a t-shirt. Fortunately, we can analyze the 3D structure of the target image and automate this process.

Sky Segmentation

Sky segmentation is a core feature in many creative tools, for example to adjust the saturation of the sky separately from the rest. Shipping a sky segmentor across multiple platforms, from mobile to the desktop, is pretty tricky though.

Firefly Video

After being one of the founders and key figures behind Adobe Firefly, I have been busy working on a foundational video model in a team led by Jianming Zhang. Like before, I have been in charge of the image data pipeline.

Intern Alumni

Throughout my career as a research scientist I had the honor to work with many brilliant students. Please find a list of my former interns here, and don't hesitate to reach out to me should you want to intern with me in the future.

Lens Blur

Bokeh is an artistic tool that allows photographers to guide attention. This typically requires large and often expensive lenses, but we can also just synthesize this effect on imagery with a shallow depth of field by simulating the underlying physics.

Structure Reference

One key ingredient for text-to-image applications is controllability, and we have recently announced Structure Reference as a form of user control. It conditions the text-to-image synthesis guided by the estimated depth of a reference image.

Benchmarking Video Frame Interpolation
Simon Kiefhaber, Simon Niklaus, Feng Liu, and Simone Schaub-Meyer

webpage / arXiv

Frame interpolation is becoming a popular research target. However, the current evaluation of interpolation techniques is not ideal. We strongly believe that the community would greatly benefit from a benchmark, which is what we propose.

Adobe Firefly

Together with Oliver Wang, Tobias Hinz, Cynthia Liu, and Kevin Matzen, I was one of the founding members of a project that later became known as Adobe Firefly. Specifically, I was in charge of anything data from data curation to data loading.

Splatting-based Synthesis for Video Frame Interpolation
Simon Niklaus, Ping Hu, and Jiawen Chen

webpage / arXiv

While deep learning has brought significant improvements to the area of frame interpolation, using a neural network to synthesize an image is prohibitively expensive. In contrast, we propose to synthesize frames purely based on splatting.

arXiv DOOM

webpage / GitHub

A video game parody of the ever-increasing number of arXiv papers. It allows you to fight the one hundred most-recent papers in the cs.CV category in a first person shooter with a DOOM aesthetic. Begin your journey to reject them all.

Project Inbetween

webpage / video

Being able to take pictures at a whim has left me with collections where many photos look alike. Given similar images, could we animate a transition between them to help us cherish past moments? This is what Project Inbetween is about.

Dark Papers

One of the few realms that do not have a dark mode yet are academic papers. This is for obvious reasons but I nevertheless wanted to give it a try to see how a dark mode academic paper would look like. Printing not recommended.

Revisiting Adaptive Convolutions for Video Frame Interpolation
Simon Niklaus, Long Mai, and Oliver Wang

webpage / arXiv / GitHub

We show, somewhat surprisingly, that it is possible to achieve near state-of-the-art frame interpolation results with an older and simpler approach, namely adaptive separable convolutions, through a subtle set of low level improvements.

Learned Dual-View Reflection Removal
S. Niklaus, X. Zhang, J. T. Barron, N. Wadhwa, R. Garg, F. Liu, and T. Xue

webpage / arXiv

Typical dereflection algorithms either use a single input image, which suffers from intrinsic ambiguities, or use multiple images from a moving camera, which is inconvenient. We instead propose an algorithm that uses stereo images as input.

NES Memoryview

webpage / GitHub

The working memory of early computers is quite small. It is so small in fact, that we can plot the history of values of each byte in memory. This demo is a NES emulator together with a time series for each byte in the 2 KB of working memory.

Softmax Splatting for Video Frame Interpolation
Simon Niklaus and Feng Liu

webpage / arXiv

Backward warping has seen broad adoption in tasks like optical flow estimation. In contrast, forward warping has seen less attention since it is unclear how to do it well. It can play a key role though, which is why we propose softmax splatting.

3D Ken Burns Effect from a Single Image
Simon Niklaus, Long Mai, Jimei Yang and Feng Liu

webpage / arXiv

The popular Ken Burns effect is an effective tool for animating still images by zooming into them. We extend this effect into the third dimension and propose a framework that, given just a single image, creates an immersive 3D zoom effect.

Moving Stills

webpage / video

We all take pictures to capture events that are dear to our heart. And while taking pictures is fun, viewing them could be more exciting at times. We breath new live into these pictures, ultimately helping us cherish and celebrate past moments.

Context-aware Synthesis for Video Frame Interpolation
Simon Niklaus and Feng Liu

webpage / arXiv

A popular framework for novel view synthesis is to warp pixels and then refine the outcome using a neural network. But why warp only in color space? We show that also warping the input in feature space helps with and improves the refinement.

Visual Computing

A class that I taught at Portland State University when I was a Ph.D. student. It covered the basics of computer vision and deep learning with a heavy focus on implementing the subject matter in Python using OpenCV and PyTorch.

WASM Raytracer

How fast is WebAssembly compared to vanilla JavaScript? I wanted to find out and implemented a simplistic raytracer with the same logic in JavaScript as well as C++ and used Emscripten to compile the C++ version to WebAssembly.

Video Frame Interpolation via Adaptive Separable Convolution
Simon Niklaus, Long Mai, and Feng Liu

webpage / arXiv

A recent approach to perform video frame interpolation convolves input frames with spatially-varying filter kernels. We show that these kernels are separable, which improves computational efficiency and interpolation quality.

Web Development

A class that I established at Portland State University when I was a Ph.D. student. I wanted students to obtain some practical web dev skills, and this class ended up being fully booked every time within minutes of the registration opening up.

Video Frame Interpolation via Adaptive Convolution
Simon Niklaus*, Long Mai*, and Feng Liu

webpage / arXiv

Frame interpolation is typically done in two steps, motion estimation and compensation. However, this heavily depends on the quality of the motion estimation. We instead propose a single-step approach through spatially-varying convolutions.

Rotating Pipes

A classic puzzle game where you have to rotate pipes such that they all connect with each other. It uses minimum spanning trees to generate the puzzles, which is implemented in C++ and run in the browser through WebAssembly.

Rollercoaster Map

I consider Rollercoaster Tycoon as one of my guilty pleasures of past times. While my parks are nothing noteworthy, there are some talented people out there, I still thought it would be fun to visualize and share them as a virtual map.

Connect Four

A connect four game, directly playable in the browser against a computer opponent with a configurable difficulty. The computer is implemented in C++ using negamax search with alpha-beta pruning and executed through WebAssembly.

Mini Chess

A miniature version of chess, playable directly in the browser against a computer opponent on different chess boards. The computer has a configurable difficulty and is implemented using negamax search with alpha-beta pruning.

Artificial Intelligence

A class that I taught when I was a Ph.D. student at Portland State on behalf of my dear friend Bart Massey. It covered the theory and practice of finding optimal and satisfying solutions to one-player and two-player combinatorial games.

Youtube Watchmarker

Youtube keeps track of your watch history and automatically marks seen videos. However, they only mark recently watched videos, which is kind of disappointing. This addon fixes this issue and keeps track of your entire watch history.
