Paper in AAAI's ICWSM (2017) "Selfie-Presentation in Everyday Life: A Large-Scale Characterization of Selfie Contexts on Instagram"
Paper Abstract Carefully managing the presentation of self via technology is a core practice on all modern social media platforms. Recently, selfies have emerged as a new, pervasive genre of identity performance. In many ways unique, selfies bring us full circle to Goffman—blending the online and offline selves together. In this paper, we take an […]

Paper in IEEE WACV (2017): "Complex Event Recognition from Images with Few Training Examples"
Paper Abstract We propose to leverage concept-level representations for complex event recognition in photographs given limited training examples. We introduce a novel framework to discover event concept attributes from the web and use that to extract semantic features from images and classify them into social event categories with few training examples. Discovered concepts include a variety of objects, scenes, […]

Research Blog: Motion Stills – Create beautiful GIFs from Live Photos
Kudos to the team from Machine Perception at Google Research that just launched the Motion Still App to generate novel photos on an iOS device. This work is in part aimed at combining efforts like Video Textures and Video Stabilization and a lot more. Today we are releasing Motion Stills, an iOS app from Google […]
Paper (WACV 2016) "Discovering Picturesque Highlights from Egocentric Vacation Videos"
Paper Abstract We present an approach for identifying picturesque highlights from large amounts of egocentric video data. Given a set of egocentric videos captured over the course of a vacation, our method analyzes the videos and looks for images that have good picturesque and artistic properties. We introduce novel techniques to automatically determine aesthetic features […]
