Robust Efficient Video Fingerprinting
We have developed a video fingerprinting system with robustness and efficiency as the primary and secondary design criteria.

Realizing Adaptive Instruction (Ad-In): the Convergence of Learning, Instruction, and Assessment
In this paper, we define adaptive instruction, or Ad-In, as applied to sophisticated skills development systems that target learning and assessment in a highly individualized and interactive manner.

Bottom-Up/Top-Down Image Parsing with Attribute Grammar
We present a simple attribute graph grammar as a generative representation for made-made scenes and studies an effective top-down/bottom-up inference algorithm for parsing images in the process of maximizing a…

FREEDIUS: an Open Source Lisp-Based Image Understanding Environment
This paper describes FREEDIUS, an open-source image understanding system. FREEDIUS is a Lisp-C hybrid system that exploits CLOS for rapid prototyping, flexibility of presentation in the user interface, and flexibility…

Discriminative Genre-Independent Audio-Visual Scene Change Detection
We present a technique for genre-independent scene-change detection using audio and video features in a discriminative support vector machine (SVM) framework.
-
FrameSLAM: from Bundle Adjustment to Real-Time Visual Mapping
In this paper, we propose a framework for applying the same techniques to visual imagery. We match visual frames with large numbers of point features.

Toward a Sentient Environment: Real-Time Wide Area Multiple Human Tracking with Identities
In this paper, we presented a fully integrated real-time computer vision system that can detect and track multiple humans in a wide-area using a network of stereo cameras.

Fast Color/Texture Segmentation for Outdoor Robots
We present results of applying our descriptor for segmenting a synthetic image and compare it against other state-of-the-art descriptors.
-
Scene-Based Nonuniformity Correction and Enhancement: Pixel Statistics and Subpixel Motion
We propose a framework for scene-based nonuniformity correction (NUC) and nonuniformity correction and enhancement (NUCE) that is required for focal-plane array-like sensors to obtain clean and enhanced-quality images.

Dynamic Facial Expression Analysis and Synthesis with Mpeg-4 Facial Animation Parameters
This paper describes a probabilistic framework for faithful reproduction of dynamic facial expressions on a synthetic face model with MPEG-4 facial animation parameters while achieving very low bitrate in data…
-
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…
