Image-features matching based on SIFT descriptors is subject to the misplacement of certain matches due to the local nature of the SIFT representations. Some well-known outlier rejectors aim to remove those misplaced matches by imposing geometrical consistency. We present two graph matching approaches (one continuous and one discrete) aimed at the matching of SIFT features in a geometrically co...

Multi-Scale Singularity Trees (MSSTs) represents the deep structure of images in scale-space and provide both the connections between image features at different scales and their strengths. In this report we present and evaluate an algorithm that exploits the MSSTs for image matching. Two versions of the algorithm is presented: an exact and an approximation. Several experiments are conducted to...

Improving our understanding of the key drivers and implications of population change Re-evaluating the link between marriage and mental well-being: How do early life conditions attenuate differences between cohabitation and marriage? i ABSTRACT The decline in marriage and increase in cohabitation raises questions about whether marriage still provides benefits to well-being. Here we use the Brit...

Recent investigations have shown the advantages of keeping multiple hypotheses during visual tracking. In this paper we explore an alternative method, which presents the concepts of histogram matching technique and absolute frame subtraction to implement a robust automated object tracking system. The object is later tracked using discrete kalman filter technique. Such a tracking system reduces ...

This work examines the ability of small-scale, helium-air-mixture, coaxial jets to capture the acoustics of large-scale hot jets representing the exhaust of separate-flow turbofan engines. Experiments at University of California, Irvine (UCI) employed a one-eighth-scale model of a separate-flow nozzle being used at the Nozzle Acoustic Test Rig (NATR) of NASA Glenn Research Center. Comparisons w...
