    Egocentric Field-of-View Localization Using First-Person Point-of-View Devices 

    Bettadapura, Vinay; Essa, Irfan; Pantofaru, Caroline (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 

    Bettadapura, Vinay; Thomaz, Edison; Parnam, Aman; Abowd, Gregory D.; Essa, Irfan (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 

    Kim, Kihwan; Lee, Dongryeol; Essa, Irfan (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 

    Hamid, Raffay; Kumar, Ram Krishan; Grundmann, Matthias; Kim, Kihwan; Essa, Irfan; Hodgins, Jessica (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 

    Grundmann, Matthias; Kwatra, Vivek; Han, Mei; Essa, Irfan (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 

    Grundmann, Matthias; Kwatra, Vivek; Han, Mei; Essa, Irfan (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 ...
