Journal ArticleDOI
Weighted Level Set Evolution Based on Local Edge Features for Medical Image Segmentation
TL;DR: Evaluation results show that the proposed method leads to more accurate boundary detection results than the state-of-the-art edge-based level set segmentation methods, particularly around weak edges.
Journal ArticleDOI
Video Anomaly Detection With Compact Feature Sets for Online Performance
TL;DR: An online framework for video anomaly detection that uses a compact set of highly descriptive features extracted from a novel cell structure that helps to define support regions in a coarse-to-fine fashion and attains a very competitive detection performance compared with state-of-the-art non-online methods.
Proceedings ArticleDOI
Planar 3D modeling of building interiors from point cloud data
Victor Sanchez,Avideh Zakhor +1 more
TL;DR: This work presents an automatic system for planar 3D modeling of building interiors from point cloud data generated by range scanners, which employs model-fitting and RANSAC, and is capable of detecting large-scale architectural structures, such as ceilings and floors, as well as small-scale architecture structures,such as staircases.
Journal ArticleDOI
Systematic Review of the Use of Computer Simulation Modeling of Patient Flow in Surgical Care
TL;DR: A comprehensive review of the literature published over the past five decades on simulation models for the flow of surgical patients found a wide variation in the presentation of assumptions, system requirements, input and output data, and results of simulation-based policy analysis.
Journal ArticleDOI
Symmetry-Based Scalable Lossless Compression of 3D Medical Image Data
TL;DR: A modified version of the embedded block coder with optimized truncation (EBCOT), tailored according to the characteristics of the data, encodes the residual data generated after prediction to provide resolution and quality scalability.
