Content-based visual information retrieval (CBVIR) or content-based image retrieval (CBIR) has been one on the most vivid research areas in the field of computer vision over the last 10 years. The availability of large and steadily growing amounts of visual and multimedia data, and the development of the Internet underline the need to create thematic access(More)
Information technology is becoming a vital component of all health care enterprises, from managed care services to large hospital networks, that provides the basis of electronic patient records and hospital-wide information. The rationale behind such systems is deceptively simple: physicians want to sit down at a single workstation and call up all(More)
A hospital-wide Picture Archiving and Communication System (PACS) is currently under development at the University Hospital of Geneva. After a first implementation including two oneterabyte optical libraries, the system is expanded to integrate all the imaging modalities of the hospital. The new storage requirement is 10 terabytes to cover three year(More)
RATIONALE AND OBJECTIVES Picture archiving and communication systems (PACS) have the vocation to manage all medical images acquired within the hospital. To address the various situations encountered in the imaging specialties, the traditional architecture used for the radiology department has to evolve. MATERIALS AND METHODS We present our preliminarily(More)
Materials and Methods. We present our preliminarily results toward an enterprise-wide PACS intended to support all kind of image production in medicine, from biomolecular images to whole-body pictures. Our solution is based on an existing radiologic PACS system from which images are distributed through an electronic patient record to all care facilities.(More)
BACKGROUND Basal cell carcinoma (BCC) is the most common type of skin cancer. One of the main problems with BCC is the risk of local recurrence of the tumor after treatment. This is mainly due to its irregular outgrowths, which cannot be detected clinically. OBJECTIVE To better understand the tumor morphology and growth pattern of BCC, we tried to develop(More)
Content based image retrieval (CBIR) systems analyze the visual content and find images in the database. this paper has been propose a novel approach to CBIR system based on prime's histogram of the color image . This paper describe a project that implements by using Matlab and test three techniques depend on the simple color histogram based search and(More)
