Egocentric Field-of-View Localization Using First-Person Point-of-View Devices
(Georgia Institute of Technology, 2015-01)
We present a technique that uses images, videos and sensor data taken from first-person point-of-view devices to perform egocentric field-of-view (FOV) localization. We define egocentric FOV localization as capturing the ...
Leveraging Context to Support Automated Food Recognition in Restaurants
(Georgia Institute of Technology, 2015-01)
The pervasiveness of mobile cameras has resulted in a
dramatic increase in food photos, which are pictures re-
flecting what people eat. In this paper, we study how tak-
ing pictures of what we eat in restaurants ...
Gaussian Process Regression Flow for Analysis of Motion Trajectories
(Georgia Institute of Technology, 2011-11)
Recognition of motions and activities of objects in videos
requires effective representations for analysis and matching
of motion trajectories. In this paper, we introduce a
new representation specifically aimed at ...
Player Localization Using Multiple Static Cameras for Sports Visualization
(Georgia Institute of Technology, 2010-06)
We present a novel approach for robust localization of multiple
people observed using multiple cameras. We use
this location information to generate sports visualizations,
which include displaying a virtual offside line ...
Efficient Hierarchical Graph-Based Video Segmentation
(Georgia Institute of Technology, 2010-06)
We present an efficient and scalable technique for spatiotemporal
segmentation of long video sequences using a
hierarchical graph-based algorithm. We begin by oversegmenting
a volumetric video graph into space-time ...
Discontinuous Seam-Carving for Video Retargeting
(Georgia Institute of Technology, 2010-06)
We introduce a new algorithm for video retargeting that
uses discontinuous seam-carving in both space and time
for resizing videos. Our algorithm relies on a novel
appearance-based temporal coherence formulation that ...
