Comprehensive Investigation on Content-based Medical Image Retrieval using Radon Barcodes
Content Based Medical Image Retrieval (CBMIR) systems are vital to the underlying operation of medical databases because they allow quick search and retrieval of medical images. Radon Barcode (RBC)s are binary complementary feature vectors which increase the speed of CBMIR systems through smaller …

Collection/item metadata relationships
… metadata is often attached to both collections and items. Collection metadata and item metadata are related: one can infer facts about items from descriptions of collections, and facts about collections from descriptions of items. This sort of reasoning, which is important to finding, …

Supporting Collocation Learning
… a key role in producing language accurately and fluently. But such knowledge is difficult to acquire, simply because there is so much of it. Collocation resources for learners are limited. Printed dictionaries are restricted in size, and only provide rudimentary search and retrieval options. …

The accessibility of memory items in children’s working memory
This thesis investigates the processes and systems that support recall in working memory. In particular it seeks to apply ideas from the adult-based dual-memory framework (Unsworth & Engle, 2007b) that claims primary memory and secondary memory are independent contributors to working memory …

Semi-Supervised Learning for Scalable and Robust Visual Search
Unlike textual document retrieval, searching of visual data is still far from satisfactory. There exist major gaps between the available solutions and practical needs in both accuracy and computational cost. This thesis aims at the development of robust and scalable solutions for visual search and …
