We make three contributions: (i) we show that with appropriate off-line processing, images can be retrieved and ROIs registered in real time; (ii) we propose and evaluate a number of scalable exemplar-based image registration schemes; (iii) we propose a discriminative method for learning to rank the returned images based on the content of the ROI. The retrieval system is demonstrated on MRI data from the ADNI dataset [9], and it is shown that the learnt ranking function outperforms the baseline.}, url = {http://approjects.co.za/?big=en-us/research/publication/immediate-roi-search-for-3d-medical-images/}, edition = {MICCAI workshop on Medical Content-based Retrieval for Clinical Decision Support (MCBR-CDS)}, }
