A Comparison Of Edge Detection Methods For Segmentation Of Skin Lesions In Mobile-Phone-Quality Images, Khanh Linh Hua
Theses : Honours
The world is faced with a rapidly increasing number of skin cancers every year. Melanoma is the most deadly type of skin cancer though it can be treated if it has been detected at an early stage. However, there is a shortage of dermatologists in rural areas. The increasing number of camera phones, together with improved coverage in rural areas gives some potential for tele-dermatology, whereby people with no local access to a dermatologist can send images of suspicious skin lesions to an expert for assessment. Merely relaying images to a human expert solves only part of the problem, there …

Video Compression Using Wavelets And Hierarchical Motion Estimation, Andrew Peter Byrne
Theses : Honours
This thesis investigates the benefits and the significant compression that can be obtained from data that has been decomposed using a wavelet transform. A video compression algorithm was developed that employs the wavelet transform and a hierarchical motion estimation algorithm which itself utilises benefits of the wavelet transform. Using MATLAB, a popular software tool for matrix based computation and analysis, several functions were developed which together formed the video compression algorithm. A variety of tests were conducted on a sample video sequence to ascertain the strengths and weaknesses of the techniques employed. The results, although not the same as the …
Storage Free Terrain Simulation, Warren Creemers
Storage Free Terrain Simulation, Warren Creemers
Theses : Honours
Landscape visualisation is the process of recreating a natural environment and displaying it in an interactive graphical simulation. To do this a terrain is displayed together with accompanying plant life and other objects. Present landscape visualisation software is capable in theory of displaying very detailed and large landscapes. The software is also in theory capable of simulating environments with thousands if not millions of individually structured plants. In practice though, the simulation of such landscapes requires such a large amount of storage space that it is not achievable on personal computers. Even storing small landscapes with a moderate amount plant …

Vhdl Design And Simulation For Embedded Zerotree Wavelet Quantisation, Hung Huynh
Vhdl Design And Simulation For Embedded Zerotree Wavelet Quantisation, Hung Huynh
Theses : Honours
This thesis discusses a highly effective still image compression algorithm – The Embedded Zerotree Wavelets coding technique, as it is called. This technique is simple but achieves a remarkable result. The image is wavelet-transformed, symbolically coded and successive quantised, therefore the compression and transmission/storage saving can be achieved by utilising the structure of zerotree. The algorithm was first proposed by Jerome M. Shapiro in 1993, however to minimise the memory usage and speeding up the EZW processor, a Depth First Search method is used to transverse across the image rather than Breadth First Search method as initially discussed in Shapiro's …
Training Methods For Shunting Inhibitory Artificial Neural Networks, Son Lam Phung
Training Methods For Shunting Inhibitory Artificial Neural Networks, Son Lam Phung
Theses : Honours
This project investigates a new class of high-order neural networks called shunting inhibitory artificial neural networks (SIANN's) and their training methods. SIANN's are biologically inspired neural networks whose dynamics are governed by a set of coupled nonlinear differential equations. The interactions among neurons are mediated via a nonlinear mechanism called shunting inhibition, which allows the neurons to operate as adaptive nonlinear filters. The project's main objective is to devise training methods, based on error backpropagation type of algorithms, which would allow SIANNs to be trained to perform feature extraction for classification and nonlinear regression tasks. The training algorithms developed will …

Implementing Flexible Software Techniques In A 4gl Environment, Stephen O'Connor
Implementing Flexible Software Techniques In A 4gl Environment, Stephen O'Connor
Theses : Honours
Today more IT professionals arc employed on the maintenance of existing software applications than are employed to develop new systems. Why is there such a need for this maintenance? Part of the problem is that developers have traditionally seen system requirements as fixed from the time they have been 'signed off. In reality requirements arc dynamic and subject to change as an organisation's environment changes. Flexible software techniques recognise that software requirements are subject to future changes. Flexibility is seen as an important design goal criterion with "true" or "strong" flexibility implying that an application's behaviour can be altered without …

Pathfinding In Vrml, Jason Richard Pearce
Pathfinding In Vrml, Jason Richard Pearce
Theses : Honours
Virtual Reality Modelling Language (VRML) is a scene description language which describes three dimensional (3D) space to a computer. Thus the three axis of space that is inherent in our dimension X Y and Z is represented inside a computer. To many people VRML represents a new beginning for the World Wide Web (WWW) because it behaves more like the real world. VRML is experimental, interactive, continuous and of course, three dimensional. Algorithms in computing have been designed for 2D problem solving and this does not necessarily translate to problem solving on a 3D level. The aim of this project …
