Proposed projects
1. Automatic detection of user
defined 2D shapes from aeromagnetic data within a GIS environment (Hons/SE)
Aeromagnetic
data captures magnetism of the Earth surface, and is one of the commonly used
dataset for targeting locations for mineral exploration. Diamond industry for example uses
aeromagnetic data to identify kimberlites (diamond
containing rocks) signature that are chracterised by
certain shapes such as circle, ellipse, ellipse with a tail, etc.. This project is to
develop an 2D shape detection system that allows
user-defined shapes to be detected in a scale- and rotation-invariant manner
from a dataset under a GIS environment.
2. Geotechnical analysis of downhole images (Hons)
Rock mass
description and characterisation is a basic task for exploration and mining
workflows. Accurate logging of the number
and type of discontinuities in the rock mass is crucial as these
discontinuities can be indicators for targeting mineral deposits and provide geotechnical
properties of the rock to identify the weak parts for the mining purpose. The aim of this project is to analyse images
captured from a downhole camera using image
processing techniques to identify and trace the discontinuities and to perform
quantitative analysis on their distribution.
