OBJECTIVE To review the pattern of ruptured intracranial aneurysms in terms of size, location, and the prevalence of multiple aneurysms in the Hong Kong Chinese population with subarachnoid haemorrhage. DESIGN Retrospective study. SETTING Three public hospitals in Hong Kong. PATIENTS A total of 267 Chinese patients with subarachnoid haemorrhage from(More)
Indexing methods play a very important role in finding information in large image databases. They organize indexed images in order to facilitate, accelerate and improve the results for later retrieval. Alternatively, clustering may be used for structuring the feature space so as to organize the dataset into groups of similar objects without prior knowledge(More)
In recent years, the expansion of acquisition devices such as digital cameras, the development of storage and transmission techniques of multimedia documents and the development of tablet computers facilitate the development of many large image databases as well as the interactions with the users. This increases the need for efficient and robust methods for(More)
The feature space structuring methods play a very important role in finding information in large image databases. They organize indexed images in order to facilitate, accelerate and improve the results of further retrieval. Clustering, one kind of feature space structuring, may organize the dataset into groups of similar objects without prior knowledge(More)
The problem of unsupervised and semi-supervised clustering is extensively studied in machine learning. In order to involve user in image data clustering, (Lai et al., 2014) proposed a new approache for interactive semi-supervised clustering that translates the feedback of user (expressed at the level of individual images) into pairwise constraints between(More)
