ToG 2012 – Bilinear Spatiotemporal Basis Models

ToG 2012 – Bilinear Spatiotemporal Basis Models

| April 10, 2012

Our paper in ACM Transactions on Graphics April 2012 presents a fundamentally new way to model time-varying point clouds, that dramatically reduces processing times for common graphics pipeline tasks such as labeling, gap-filling, denoising, and motion touch-up. This is joint work with Carnegie Mellon University and Disney Research Pittsburgh, and has been presented at Siggraph 2012.

TIP 2012 – Correlation Coefficient Based Fast Template Matching Through Partial Elimination

TIP 2012 – Correlation Coefficient Based Fast Template Matching Through Partial Elimination

| April 1, 2012

Arif Mahmood, Sohaib Khan IEEE Transactions on Image Processing, Vol 21, No 4, April 2012 Abstract Partial computation elimination techniques are often used for fast template matching. At a particular search location, computations are prematurely terminated as soon as it is found that this location cannot compete already known best-match location. Due to non-monotonic growth […]

TPAMI 2011 – Trajectory Space: A Dual Representation for Nonrigid Structure from Motion

| July 1, 2011

Ijaz Akhter, Yaser Sheikh, Sohaib Khan, Takeo Kanade IEEE Transactions on Pattern Analysis and Machine Intelligence, Vol 33, No 7, Jul 2011 Abstract Existing approaches to nonrigid structure from motion assume that the instantaneous 3D shape of a deforming object is a linear combination of basis shapes. These basis are object dependent and therefore have […]

SPM 2011 – Distributed and Decentralized Multi-Camera Tracking: A Survey

| May 13, 2011

Murtaza Taj, Andrea Cavallaro IEEE Signal Processing Magazine, 2011 Abstract In recent years the decreasing cost of cameras and advances in miniaturization have favoured the deployment of largescale camera networks. This growing number of cameras enables new signal processing applications that use cooperatively multiple sensors over wide areas. In particular, object tracking is an important […]

TIP 2010 – Exploiting Transitivity of Correlation for Fast Template Matching

| August 8, 2010

Arif Mahmood, Sohaib Khan IEEE Transactions on Image Processing, Vol 19, N0. 8, Aug 2010 Abstract Elimination Algorithms are often used in template matching to provide a significant speed-up by skipping portions of the computation while guaranteeing the same best-match location as exhaustive search. In this work, we develop elimination algorithms for correlation-based match measures […]

Tariq Butt, Tabish Mufti, Ahmad Humayun, Peter B. Rosenthal, Sohaib Khan, Shahid Khan, Justin E. Molloy Journal of Biological Chemistry, Vol 285, No 7, Feb 12, 2010¬† Abstract The bulk alignment of actin filament sliding movement, powered by randomly oriented myosin molecules, has been observed and studied using an in vitro motility assay. The well […]

MTA 2009 – Content and Task-Based View Selection from Multiple Video Streams

MTA 2009 – Content and Task-Based View Selection from Multiple Video Streams

| January 13, 2009

Fahad Daniyal, Murtaza Taj, Andrea Cavallaro Multimedia Tools and Applications, 2009 Abstract We present a content-aware multi-camera selection technique that uses object and frame-level features. First objects are detected using a color-based change detector. Next trajectory information for each object is generated using multi-frame graph matching. Finally, multiple features including size and location are used […]

JSTSP 2008 – Target detection and tracking with heterogeneous sensors

| August 13, 2008

Huiyu Zhou, Murtaza Taj, Andrea Cavallaro IEEE Journal of Selected Topics in Signal Processing, 2008 Abstract We present a multimodal detection and tracking algorithm for sensors composed of a camera mounted between two microphones. Target localization is performed on color-based change detection in the video modality and on Time Difference of Arrival (TDOA) estimation between […]

TCSVT 2008 – Efficient Multi-Target Visual Tracking Using Random Finite Sets

| August 13, 2008

Emilio Maggio,¬†Murtaza Taj, Andrea Cavallaro IEEE Transaction on Circuits System and Video Technology, 2008 Abstract We propose a filtering framework for multi-target tracking that is based on the Probability Hypothesis Density (PHD) filter and data association using graph matching. This framework can be combined with any object detectors that generate positional and dimensional information of […]

EURASIP 2008 – Detection and Tracking of Humans and Faces

| January 13, 2008

Stefan Karlsson,¬†Murtaza Taj, Andrea Cavallaro EURASIP Journal on Image and Video Processing, 2008 Abstract We present a video analysis framework that integrates prior knowledge in object tracking to automatically detect humans and faces, and can be used to generate abstract representations of video (key-objects and object trajectories). The analysis framework is based on the fusion […]
