We have developed a novel system for content-based image retrieval in large, unannotated databases. The system is called PicSOM, and it is based on tree structured self-organizing maps (TS-SOMs). Given a set of reference images, PicSOM is able to retrieve another set of images which are similar to the given ones. Each TS-SOM is formed with a di€erent image(More)
OBJECTIVES The pharmacokinetics of toremifene was investigated in an open study with four parallel groups of 10 subjects each. Subjects with impaired liver function (biopsy-proven liver disease), activated liver function (drug-induced), and impaired kidney function were compared with normal subjects. METHODS A single oral 120 mg dose of toremifene was(More)
A high-performance liquid chromatographic method for the determination of plasma concentrations of erythromycin base and 2'-acetylerythromycin, an ester prodrug of erythromycin, is described. tert.-Butyl methyl ether extracts of 1-ml plasma samples (pH 10) were chromatographed on a C18 reversed-phase column. A three-electrode coulometric detector (oxidation(More)
Self-Organising Maps (SOMs) can be used in implementing a powerful relevance feedback mechanism for Content-Based Image Retrieval (CBIR). This paper introduces the PicSOM CBIR system, and describes the use of SOMs as a relevance feedback technique in it. The technique is based on the SOM's inherent property of topology-preserving mapping from a(More)
We have designed and evaluated a novel multiplayer game system using just one top-view camera. With the proposed system, player avatar movement can be directly mapped to the physical movement of the player, accompanied by additional hand gestures triggering more complex actions. This article presents a study of the concepts of body-driven multiplayer games(More)
We have developed a method that utilizes hypertext link information in image retrieval from the World Wide Web. The basis of the method consists of a set of basic relations that can take place between two images in the Web. Our method uses the SHA-1 message digest algorithm for dimension reduction by random mapping. The Web link features have then been used(More)
We have developed an experimental system called PicSOM for retrieving images similar to a given set of reference images in large unannotated image databases. The technique is based on a hierarchical variant of the Self-Organizing Map (SOM) called the Tree Structured Self-Organizing Map (TS-SOM). Given a set of reference images, PicSOM is able to retrieve(More)
Content-based image retrieval (CBIR) is a new but in recent years widely-adopted method for nding images from vast and unanno-tated image databases. CBIR is a technique for querying images on the basis of automatically-derived features such as color, texture, and shape directly from the visual content of images. For the development of eeec-tive image(More)
