Floors are Flat: Leveraging Semantics for Real-Time Surface Normal Prediction

1 code implementation16 Jun 2019 Steven Hickson, Karthik Raveendran, Alireza Fathi, Kevin Murphy, Irfan Essa

We propose 4 insights that help to significantly improve the performance of deep learning models that predict surface normals and semantic labels from a single RGB image.

Efficient Hierarchical Graph-Based Segmentation of RGBD Videos

1 code implementation CVPR 2014 Steven Hickson, Stan Birchfield, Irfan Essa, Henrik Christensen

We present an efficient and scalable algorithm for segmenting 3D RGBD point clouds by combining depth, color, and temporal information using a multistage, hierarchical graph-based approach.

Object category learning and retrieval with weak supervision

1 code implementation26 Jan 2018 Steven Hickson, Anelia Angelova, Irfan Essa, Rahul Sukthankar

We consider the problem of retrieving objects from image data and learning to classify them into meaningful semantic categories with minimal supervision.

Let's Dance: Learning From Online Dance Videos

1 code implementation23 Jan 2018 Daniel Castro, Steven Hickson, Patsorn Sangkloy, Bhavishya Mittal, Sean Dai, James Hays, Irfan Essa

We present a comparison of numerous state-of-the-art techniques on our dataset using three different representations (video, optical flow and multi-person pose data) in order to analyze these approaches.

Semantic Instance Labeling Leveraging Hierarchical Segmentation

1 code implementation2 Aug 2017 Steven Hickson, Irfan Essa, Henrik Christensen

Most of the approaches for indoor RGBD semantic la- beling focus on using pixels or superpixels to train a classi- fier.

An Energy Minimization Approach to 3D Non-Rigid Deformable Surface Estimation Using RGBD Data

no code implementations2 Aug 2017 Bryan Willimon, Steven Hickson, Ian Walker, Stan Birchfield

In particular, we show that our method is able to estimate the configuration of a textureless nonrigid object with no correspondences available.

Eyemotion: Classifying facial expressions in VR using eye-tracking cameras

no code implementations22 Jul 2017 Steven Hickson, Nick Dufour, Avneesh Sud, Vivek Kwatra, Irfan Essa

One of the main challenges of social interaction in virtual reality settings is that head-mounted displays occlude a large portion of the face, blocking facial expressions and thereby restricting social engagement cues among users.

Predicting Daily Activities From Egocentric Images Using Deep Learning

no code implementations6 Oct 2015 Daniel Castro, Steven Hickson, Vinay Bettadapura, Edison Thomaz, Gregory Abowd, Henrik Christensen, Irfan Essa

We collected a dataset of 40, 103 egocentric images over a 6 month period with 19 activity classes and demonstrate the benefit of state-of-the-art deep learning techniques for learning and predicting daily activities.
