WordRev: Finding Word-Level Structures in a Sea of Bit-Level Gates
In this paper, we present a systemic way of automatically deriving word-level structures from the gate-level netlist of a digital circuit. We demonstrate the effectiveness of our approach on a…

3D Visual Proxemics: Recognizing Human Interactions in 3D from a Single Image
We present a unified framework for detecting and classifying people interactions in unconstrained user generated images.

On the Applicability of Speaker Diarization to Audio Indexing of Non-Speech and Mixed Non-Speech/Speech Video
This paper explores how unsupervised audio segmentation systems like speaker diarization can be adapted to automatically identify low-level sound concepts similar to annotator defined concepts and how these concepts can…

Enabling Hardware Exploration in Software-Defined Networking: A Flexible, Portable Openflow Switch
We present an FPGA-based switch which is fully-compliant with OpenFlow 1.0, and meets the 10 Gbps line rate.

Towards a Theory of Application Compartmentalisation
Drawing a comparison with capability systems, we consider how a distributed system interpretation supports an argument that compartmentalisation improves application security.

R-MASTIF: Robotic Mobile Autonomous System for Threat Interrogation and Object Fetch
The SRI-UPenn team fielded a modified Segway RMP 200 robot with multiple cameras and lidars. We implemented a unique computer vision based approach for textureless colored object training and detection…

Video Event Recognition Using Concept Attributes
We propose to use action, scene and object concepts as semantic attributes for classification of video events in InTheWild content, such as YouTube videos.

A General Approach to Online Sensor Calibration for Navigation Using Factor Graphs
We present a general method for online sensor calibration using factor graphs, which can be applied to a wide range of sensors and parameter types.

Vision Guided Compression on Low-Bit Rate Channels
We introduce Vision Guided Compression (VGC), as a pre-processing technology that can be coupled with standards-based video coding, to provide FMV at low-bit rates.
