One-Vote Veto: Semi-Supervised Learning for Low-Shot Glaucoma Diagnosis

no code implementations9 Dec 2020 Rui Fan, Christopher Bowd, Nicole Brye, Mark Christopher, Robert N. Weinreb, David Kriegman, Linda M. Zangwill

Our proposed multi-task Siamese network (MTSN) can employ any backbone CNN, and we demonstrate with four backbone CNNs that its accuracy with limited training data approaches the accuracy of backbone CNNs trained with a dataset that is 50 times larger.

Neural Reflectance Fields for Appearance Acquisition

no code implementations9 Aug 2020 Sai Bi, Zexiang Xu, Pratul Srinivasan, Ben Mildenhall, Kalyan Sunkavalli, Miloš Hašan, Yannick Hold-Geoffroy, David Kriegman, Ravi Ramamoorthi

We combine this representation with a physically-based differentiable ray marching framework that can render images from a neural reflectance field under any viewpoint and light.

Deep 3D Capture: Geometry and Reflectance from Sparse Multi-View Images

no code implementations CVPR 2020 Sai Bi, Zexiang Xu, Kalyan Sunkavalli, David Kriegman, Ravi Ramamoorthi

We introduce a novel learning-based method to reconstruct the high-quality geometry and complex, spatially-varying BRDF of an arbitrary object from a sparse set of only six images captured by wide-baseline cameras under collocated point lighting.

Detecting the Starting Frame of Actions in Video

1 code implementation7 Jun 2019 Iljung S. Kwak, Jian-Zhong Guo, Adam Hantman, David Kriegman, Kristin Branson

In this work, we address the problem of precisely localizing key frames of an action, for example, the precise time that a pitcher releases a baseball, or the precise time that a crowd begins to applaud.

Action Recognition

Image to Image Translation for Domain Adaptation

no code implementations CVPR 2018 Zak Murez, Soheil Kolouri, David Kriegman, Ravi Ramamoorthi, Kyungnam Kim

This is achieved by adding extra networks and losses that help regularize the features extracted by the backbone encoder network.

Depth and Image Restoration From Light Field in a Scattering Medium

no code implementations ICCV 2017 Jiandong Tian, Zachary Murez, Tong Cui, Zhen Zhang, David Kriegman, Ravi Ramamoorthi

First, we present a new single image restoration algorithm which removes backscatter and attenuation from images better than existing methods, and apply it to each view in the light field.

Dense Volume-to-Volume Vascular Boundary Detection

1 code implementation26 May 2016 Jameson Merkow, David Kriegman, Alison Marsden, Zhuowen Tu

In this work, we present a novel 3D-Convolutional Neural Network (CNN) architecture called I2I-3D that predicts boundary location in volumetric data.

Learning Concept Embeddings with Combined Human-Machine Expertise

no code implementations ICCV 2015 Michael J. Wilber, Iljung S. Kwak, David Kriegman, Serge Belongie

This paper presents our work on "SNaCK," a low-dimensional concept embedding algorithm that combines human expertise with automatic machine similarity kernels.

Locally Uniform Comparison Image Descriptor

no code implementations NeurIPS 2012 Andrew Ziegler, Eric Christiansen, David Kriegman, Serge J. Belongie

Keypoint matching between pairs of images using popular descriptors like SIFT or a faster variant called SURF is at the heart of many computer vision algorithms including recognition, mosaicing, and structure from motion.
