Summary on Grant Application Form
This proposal addresses the problem of compressing digital angiograms for application to data storage within large cardiology units and low bandwidth transmission from cardiology units within district general hospitals and mobile units. The problem is a difficult one since, whilst the useful information within each frame of the video sequence is spatially localised, automatic detection of the main coronary arteries and any narrowing of the arteries, is problematic. Also, the background is noisy and the interframe motion complex. Finally, standard rigid-body motion models commonly assumed for standard video compression techniques such as MPEG, are not applicable.The research programme will look at ways in which the frames can be segmented into areas which must be reconstructed accurately from the decompressed video and areas which contain less useful information and can tolerate reconstruction errors and how this segmentation can be tracked between frames. A second stage will consider the spatio-temporal modelling of features within each region in order to develop a multi-strategy video coder, which can take into account the different coding requirements from each region.Evaluation will be based on expert end-user assessment diagnostic quality of the decompressed video to the original.
