The Publication is following the yearly Editions of EVA FLORENCE. The State of Art is presented regarding the Application of Technologies (in particular of digital type) to Cultural Heritage. The more recent results of the Researches in the considered Area are presented. Information Technologies of interest for Culture Heritage are presented: multimedia systems, data-bases, data protection, access to digital content, Virtual Galleries. Particular reference is reserved to digital images (Electronic Imaging & the Visual Arts), regarding Cultural Institutions (Museums, Libraries, Palace - Monuments, Archaeological Sites). The International Conference includes the following Sessions: Strategic Issues; New Sciences and Culture Developments and Applications; New Technical Developments & Applications; Museums - Virtual Galleries and Related Initiatives; Art and Humanities Ecosystem & Applications; Access to the Culture Information. Two Workshops regard: Innovation and Enterprise; the Cloud Systems connected to the Culture (eCulture Cloud) in the Smart Cities context. The more recent results of the Researches at national and international are reported in the Area of Technologies and Culture Heritage, also with experimental demonstrations of developed Activities

Automatic dental caries detection in bitewing radiographs.

Doctoral Degree. University of KwaZulu-Natal, Durban.Dental Caries is one of the most prevalent chronic disease around the globe. Distinguishing carious lesions has been a challenging task. Conventional computer aided diagnosis and detection methods in the past have heavily relied on visual inspection of teeth. These are only effective on large and clearly visible caries on affected teeth. Conventional methods have been limited in performance due to the complex visual characteristics of dental caries images, which consists of hidden or inaccessible lesions. Early detection of dental caries is an important determinant for treatment and benefits much from the introduction of new tools such as dental radiography. A method for the segmentation of teeth in bitewing X-rays is presented in this thesis, as well as a method for the detection of dental caries on X-ray images using a supervised model. The diagnostic method proposed uses an assessment protocol that is evaluated according to a set of identifiers obtained from a learning model. The proposed technique automatically detects hidden and inaccessible dental caries lesions in bitewing radio graphs. The approach employed data augmentation to increase the number of images in the data set in order to have a total of 11,114 dental images. Image pre-processing on the data set was through the use of Gaussian blur filters. Image segmentation was handled through thresholding, erosion and dilation morphology, while image boundary detection was achieved through active contours method. Furthermore, the deep learning based network through the sequential model in Keras extracts features from the images through blob detection. Finally, a convexity threshold value of 0.9 is introduced to aid in the classification of caries as either present or not present. The relative efficacy of the supervised model in diagnosing dental caries when compared to current systems is indicated by the results detailed in this thesis. The proposed model achieved a 97% correct diagnostic which proved quite competitive with existing models.Author's Publications are listed on page 4 of this thesis

Ownership and Authorship in Copyright Law (A Proposal to Re-Categorise Works and a Digital Implementation)

The thesis argues that there is a pressure on the authorship concept since the emergence of collections of facts, anthologies, and adaptations of pre-existing works. These works were the reason that Judges offered various interpretations to authorship and originality, as some Judges lessened the requirement of originality to obtain copyrightability for these works and some raised it. This led to make the protection granted by copyright law to intellectual works vague and uncertain. This became apparent in conflicts in courts decisions on copyright subsistence in works. This subsequently led to confusion around the criteria of interpretation that should be adopted and the theory or justification that copyright law is founded upon. The thesis argues that this vagueness and uncertainty is related not to the authorship concept but to the failure of law to adapt to two separate natures of works, one including authorial, mental and personal contribution and the other only including manually skilful contribution. Those two kinds cannot be subject to same principles or justifications of protection. The inexistence of such differentiation in doctrine, judiciary and legislation led to the distortion of authorship and originality concepts in the attempts to reduce their interpretation to suit those works that actually miss authorial contribution. Alternatively, whole attention was paid to granting ownership to right holders of these works, which led to the prevalence of the ownership concept as being a necessity for the marketability of cultural works over the authorship concept. The thesis finds that this difference in nature can be uncovered by settling on a differentiation between two kinds of skills that are used in creating works: the mental skills, which are authorial skills, on the one side, and manual skills, which are the collecting, combining, performing or executing skills, on the other. Accordingly, this thesis proposes a categorisation of works, that of ‘high, low and non-authorship’ works, which relies on the nature of the works and elements of authorship in the work. The thesis finds that every category of works needs a separate criterion that can suit its nature and constituent authorship elements; also, the protection needs to be graded depending on the level of authorship in the work. This thesis suggests that such a legal proposition be implemented digitally in what it calls the ‘Digital Cultural National Gate’, which decides the category the work should belong to and the correspondent protection, and that through some questionnaires on the work the authorship elements can be recognised.Egyptian Government, Ministry of Higher Education, represented by The Egyptian Cultural Office in London
