Scene-Based Nonuniformity Correction Using Local Constant Statistics
Our method proposes a local-constant statistics that assumes that the temporal signal distribution is not constant at each pixel but is locally true.

Mosaicing of Single Plane Illumination Microscopy Images Using Groupwise Registration and Fast Content-Based Image Fusion
We propose here an image mosaicing algorithm that combines state of the art groupwise image registration for alignment with content-based image fusion to prevent degrading of the fused image due…

Deciding Entailment and Contradiction with Stochastic and Edit Distance-based Alignment.
We use typed dependency graphs generated by the Stanford parser (Klein and Manning, 2003; de Marneffe et al., 2006), which contain a node for each word and labeled edges representing…

CenSurE: Center Surround Extremas for Realtime Feature Detection and Matching
We explore the suitability of different feature detectors for the task of image registration, and in particular for visual odometry, using two criteria: stability and accuracy.

Vehicle and Person Tracking in Aerial Videos
This paper presents two tracking approaches from Sarnoff Corporation to detect moving vehicles and person in the videos taken from aerial platform or plane.

Probabilistic Global Motion Estimation Based on Laplacian Two-Bit Plane Matching for Fast Digital Image Stabilization
This paper proposes a new DIS algorithm that reduces the computation time while preserving the accuracy of the algorithm. To reduce the computation time, an image is transformed by a…

Qualitative Assessment of Video Stabilization and Mosaicing Systems
This paper suggests an evaluation methodology which would provide us the ability to qualitatively measure the performance of a given stabilized system.

Pose-Encoded Spherical Harmonics for Face Recognition and Synthesis Using a Single Image
In this paper, we propose to address one of the most challenging scenarios in face recognition. That is, to identify a subject from a test image that is acquired under…

Fostering Collaboration with a Semantic Index over Textual Contributions
We are exploring new approaches to facilitating effective collaboration that remove or reduce common barriers and that exploit opportunities to encourage more effective collaboration, including transcending the cognitive biases of…

PHERL: an Emerging Representation Language for Patterns, Hypotheses, and Evidence
We are developing PHERL, an interchange language for link analysis tools, which is designed to support the sharing of patterns and hypotheses (e.g., pattern-match results).

Activity Recognition and Abnormality Detection with the Switching Hidden Semi-Markov model
We introduce the Switching Hidden Semi-Markov Model (S-HSMM), a two-layered extension of the hidden semi-Markov model (HSMM) for the modeling task.
