The Kalman filter (KF) has been improved for a mobile robot to human tracking. The proposed algorithm combines a curve matching framework and KF to enhance prediction accuracy of target tracking. Compared to other methods using normal KF, the Curve Matched Kalman Filter (CMKF) method predicts the next movement of the human by taking into account not only his present motion characteristics, but ...

We approach the problem of 2-D and 3-D puzzle solving by matching the geometric features of puzzle pieces three at a time. First, we define an affinity measure for a pair of pieces in two stages, one based on a coarse-scale representation of curves and one based on a fine-scale elastic curve matching method. This re-examination of the top coarse-scale matches at the fine scale results in an opt...

This paper highlights the progress of the research programme for investigating spatio-temporal volume based video event detection. The main research aim is to devise innovative and efficient volume-based video content analysis techniques and systems. To tackle this challenge, this paper fouces on the subjects of volume based feature analysis and event template matching. Corresponding system pro...

Realistic image-based 3D reconstruction of narrow plants, such as wheat and barley, is challenging because of plant’s lack of a well defined surface, complex self-occlusions, and high degree of self-similarities. In this paper we present a new approach for image-based modeling of plants using a pair of cameras in a stereo setup. Our key idea is that while color and texture features are unlikely...

Dice similarity coefficients (DSC) of single best matching (SBM) and multiple best matching (MBM) prostate bed automated atlas-based segmentation (AABS) contours were compared to an expert panel gold standard. DSC scores improved with MBM in bladder (0.73-0.82) and penile bulb (0.40-0.54), with no improvement in other organs. Categories: Radiation Oncology, Urology, Oncology

BACKGROUND Implementing semi-automated processes to efficiently match patients to clinical trials at the point of care requires both detailed patient data and authoritative information about open studies. OBJECTIVE To evaluate the utility of the ClinicalTrials.gov registry as a data source for semi-automated trial eligibility screening. METHODS Eligibility criteria and metadata for 437 tria...
