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 […]

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 […]

ICIP 2009 – Early Termination Algorithms for Adaboost Based Detectors

| November 8, 2009

Arif Mahmood, Sohaib Khan 16th International Conference on Image Processing, Cairo, Egypt, Nov 7-10, 2009 Abstract In this paper we propose an early termination algorithm for speeding up the detection phase of the Adaboost based de- tectors. In the basic algorithm, at a specific search location, the AdaBoost ensemble response is computed as monotonic decreasing […]

BMVC 2009 – VillageFinder: Segmentation of Nucleated Villages in Satellite Imagery

| September 8, 2009

Kashif Murtaza, Sohaib Khan, Nasir Rajpoot British Machine Vision Conference (BMVC), September 2009 Abstract Geo-spatial data on village locations, their size, population and other parameters is scarcely available to decision makers in many developing countries. In this paper, we demonstrate an automatic “crawler” which can segment nucleated villages from satellite imagery freely available in public […]

CVPR 2009 – In Defense of Orthonormality Constraints for Nonrigid Structure from Motion

| June 8, 2009

Ijaz Akhter, Yaser Sheikh, Sohaib Khan IEEE Conference on Computer Vision and Pattern Recognition (CVPR) 2009 (Oral, 4.1% acceptance rate) Abstract In factorization approaches to nonrigid structure from motion, the 3D shape of a deforming object is usually modeled as a linear combination of a small number of basis shapes. The original approach to simultaneously […]

ICIP 2008 – Exploiting Local Auto-Correlation Function for Fast Video-to-Reference Image Alignment

| October 9, 2008

Arif Mahmood, Sohaib Khan 15th IEEE International Conference on Image Processing, ICIP 2008 Abstract Digital images of natural scenes are usually characterized by strong spatial correlation between adjacent pixels which has been successfully exploited in the coding of still and moving pictures. In this work we show that the strong spatial correlation of natural images […]
