Description of Research Interests
Thesis: My thesis was primarily concerned with the impact of motion estimation failures on the performance of digital restoration processes, specifically missing data treatment and tear removal. Image & Video Restoration: My work in restoration has focused on Film Tear Restoration and Robust Missing Data Detection in Archived Media. I have also worked on noise detection and estimation. 3D-Stereoscopic Image & Video Processing: I worked for some time on the EI funded HIROP project and designed a prototype to measure the surface roughness of a grinding wheel by constructing a 3D model of a grinding wheel. As part of the SFI funded CAMP project, I was involved in the construction of 3D-Stereoscopic databases for post-production research as well as surface anatomy training videos for medical students and artists. Currently, I am working algorithms to restore image burnout in 3d-stereo video sequences. My current research interests are in depth perception in virtual depth perception in stereo-3D environments. Image Processing for Seabed Analysis: I have been involved with the supervision of a student involved in developing image processing techniques for seabed videos. Applications have focused on image restoration to improve the video quality as well as image analysis applications to aid surveys of Nephrop populations. Image Processing for Microscopy: I have supervised students working on image processing applications for microscopy. This has included work on segmentation and shape modelling of cells, cell nuclei and neuron synapses as well as looking at image restoration techniques for high resolution imaging on the Atomic Force Microscope. Video Object Segmentation: I developed a method for segmenting foreground objects from a video using a joint likelihood model based on observations of colour statistics and object motion. Other Research: I have also working on an algorithm to generate mosaics from MPEG-streams of sports events . These mosaics were designed as a means to allow summarisation of sports events for efficient transmission over low bit-rate networks. I have also investigated the use of the complex wavelet transform for non-parametric texture synthesis.
