Quick Abstract

A way to practice Telemedicine is to access a data-base capable to assist you in medical procedures (diagnosis, treatment and prognosis), similarly to consult a book or to ask a college. In many countries the lack of specialists and training capabilities demand to practice solo-medicine, that in the case of surgery require robots capable to induce anesthesia or help in vision or handling instruments. A relevant case is the diagnostic self-training requirements for optical biopsies (OBs) obtained with confocal laser endomicroscopy (CLE) or the assistance in the diagnosis of pathology slides. In both cases it is required a training set of digital images against which to compare the question case by means of image-queryformat. The present paper present a content-based image retrieval system (CBIR) based on the MPEG Query Format Standard in order to provide a set of similar pictures and the corresponding diagnosis to help on diagnosis or just to train the doctor. The paper defined the Image Solo-Medicine Paradigm (ISMP) architecture merging medical image standards and MPEG and JPEG standards. It tested the solution with normal, and benign colon OBs with 90% congruency. The ISMP is of particular interest viewed the proliferation of iPhone medical applications aiming to train doctors and support medical decisions.

Quick Abstract

The use of Optical Biopsies-OB (in the present case Confocal endomicroscopy-CEM) is limited due to difficulties to interpret images. The OB-CEM are taken by endoscopists, not trained in microscopic mor-phology which is the domain of the surgical pathology. To gain diagnostic confidence the endoscopists could consult the images to a pathologist or could use the technique proposed in the paper. That is, to search for similar images on Internet to compare the diagnosis. The present paper is a positioning paper of how to build a CEM-image metadata to be used by the multimedia standards ISO-15938-12:2008 and ISO-24800-3 in order to search on line using a “query by image”. Metadata semantics based on Kudo colorectal crypt architecture was used for annotation or automatic image extraction. The training set was composed of 25 OB-CEM chromo-colonoscopy images taken with a FICE (Fujinon Intelligent Chromoendoscopy). Those parameters were, whenever possible, automatically extracted from the image and included in the metadata for image mining. Future developments will annotate histological images is such a way that the query could also retrieve the histological image.

Quick Abstract

In this paper, we present an innovative architecture that enables the digital representation of original works and derivatives while implementing Digital Rights Management (DRM) with the aim of focusing on promoting trust within the multimedia content value networks rather than solely on content access and protection control. The system combines different features common in DRM systems such as licensing, content protection, authorisation and reporting together with innovative concepts, such as the linkage of original and derived content and the definition of potential rights. The transmission of reporting requests across the content value network combined with the possibility for authors to exercise rights over derivative works enables the system to determine automatically the percentage of income corresponding to each of the actors involved in different steps of the creation and distribution chain. The implementation consists of a web application which interacts with different external services plus a user application used to render protected content. It is currently publicly accessible for evaluation.

Quick Abstract

Ontologies represent knowledge in a particular area. Intellectual Property (IP) Entities lifecycle lacks any explicit standard representation, and a semantic expression of its processes and rules would report a series of benefits. To formalize the expression of IP Entities and their relations, an Ontology Web Language (OWL) ontology is proposed to establish a common framework where the different interested parties can interact. As a demonstration, a sample application based on the ontology is described, where a central reasoning server receives qualified statements and queries over the ontology, giving the pertinent logical results.

Quick Abstract

Digital Rights Management (DRM) is an important issue when trying to provide advanced multimedia content distribution services. DRM is mostly thought for personal computers, but now, with the emerging mobile devices which include multimedia support and higher bandwidth capabilities, users demand more valuable content for their mobile devices. The most relevant initiatives in the area, MPEG 21 and OMA DRM have been used for implementing a DRM system for mobiles. A lot of work has still to be done in this area and what we present here is a combination of techniques coming from MPEG 21 and OMA for providing a more complex system with combined capabilities.

SECURE LICENSE MANAGEMENT - Management of Digital Object Licenses in a DRM Environment

Quick Abstract

In the digital world protecting digital intellectual property is proving to be a hard task. Not only it is complex to provide robust and reliable mechanisms to prevent unauthorized content copying and utilization, but also it is complex to provide a mechanism for specifying and enforcing how content can and will be used. Rights expression languages allow content providers and distributors to syntactically and semantically to express a set of rights that are associated to a digital object. In this paper we will provide the definition and description of the digital object license granting rights life cycle management and processes necessary to secure the license throughout this entire life cycle.
