Automatic Detection of Pulmonary Embolism using Computational Intelligence
Simon Scurrell, Tshilidzi Marwala, David Rubin
This article describes the implementation of a system designed to automatically detect the presence of pulmonary embolism in lung scans. These images are firstly segmented, before…
An Independent Evaluation of Subspace Face Recognition Algorithms
Dhiresh R. Surajpal, Tshilidzi Marwala
This paper explores a comparative study of both the linear and kernel implementations of three of the most popular Appearance-based Face Recognition projection classes, these being…
Enhancement of Noisy Planar Nuclear Medicine Images using Mean Field Annealing
D. L. Falk, D. M. Rubin, T. Marwala
Nuclear medicine (NM) images inherently suffer from large amounts of noise and blur. The purpose of this research is to reduce the noise and blur while maintaining image integrity…
Medical Image Segmentation and Localization using Deformable Templates
Jonathan M. Spiller, T. Marwala
This paper presents deformable templates as a tool for segmentation and localization of biological structures in medical images. Structures are represented by a prototype template,…
Rough Sets Computations to Impute Missing Data
Fulufhelo Vincent Nelwamondo, Tshilidzi Marwala
Many techniques for handling missing data have been proposed in the literature. Most of these techniques are overly complex. This paper explores an imputation technique based on ro…
