Authors Vincent Chen, Paroma Varma, Ranjay Krishna, Michael Bernstein, Christopher Re, Li Fei-Fei Our semi-supervised method automatically generates probabilistic relationship labels to train any scene graph model. Abstract Visual knowledge bases such as Visual Genome power numerous applications in computer vision, like visual question answering and captioning, but suffer from sparse, incomplete relationships. All scene

Authors Apoorva Dornadula, Austin Narcomey, Ranjay Krishna, Michael Bernstein, Li Fei-Fei We introduce a scene graph approach that formulates predicates as learned functions, which result in an embedding space for objects that is effective for few-shot. Our formulation treats predicates as learned semantic and spatial functions, which are trained within a graph convolution network. First,

Authors Sean J. Liu, Maneesh Agrawala, Stephen DiVerdi, Aaron Hertzmann In 360◦ video, viewers can look anywhere at any time. In the opening scene of Invasion!, a rabbit emerges from a cave (a). In sequential playback, a viewer looking at the cave (green box) will see the rabbit emerge, whereas a viewer not looking at

Authors Junwon Park, Ranjay Krishna, Pranav Khadpe, Li Fei-Fei, Michael Bernstein Abstract To support the massive data requirements of modern supervised machine learning (ML) algorithms, crowdsourcing systems match volunteer contributors to appropriate tasks. Such systems learn “what” types of tasks contributors are interested to complete. In this paper, instead of focusing on “what” to ask,

Authors O. Fried, A. Tewari, M. Zollhöfer, A. Finkelstein, E. Shechtman, D. B Goldman, K. Genova, Z. Jin, C. Theobalt and M. Agrawala We propose a novel text-based editing approach for talking-head video. Given an edited transcript, our approach produces a realistic output video in which the dialogue of the speaker has been modified and

Authors O. Fried and M. Agrawala Given an audio file and a puppet video, we produce a dubbed result in which the puppet is saying the new audio phrase with proper mouth articulation. Specifically, each syllable of the input audio matches a closed-open-closed mouth sequence in our dubbed result. We present two methods, one semi-automatic

Authors Ranjay Krishna, Michael Bernstein, Li Fei-Fei Example questions generated for a set of images and answer categories. Incorrect questions are shown in grey and occur when no relevant question van be generated for a given image and answer category Abstract Though image-to-sequence generation models have become overwhelmingly popular in human-computer communications, they suffer from

Authors Kenji Hata, Ranjay Krishna, Li Fei-Fei, Michael Bernstein A selection of individual workers’ accuracy over time during the question answering task. Each worker remains relatively constant throughout his or her entire lifetime. Abstract Microtask crowdsourcing is increasingly critical to the creation of extremely large datasets. As a result, crowd workers spend weeks or months

Authors Ranjay Krishna, Yuke Zhu, Oliver Groth, Justin Johnson, Kenji Hata, Joshua Kravitz, Stephanie Chen, Yannis Kalantidis, Li Jia-Li, David Ayman Shamma, Michael Bernstein, Li Fei-Fei An overview of the data needed to move from perceptual awareness to cognitive understanding of images. We present a dataset of images densely annotated with numerous region descriptions, objects,
