Detection and classification of microcalcifications clusters in digitized mammograms
2005
In the present paper we discuss a new approach for the detection of microcalcification clusters, based on neural networks and developed as part of the MAGIC-5 project, an INFN-funded program which aims at the development and implementation of CAD algorithms in a GRID-based distributed environment. The proposed approach has as its roots the desire to maximize the rejection of background during the analytical pre-processing stage, in order to train and test the neural network with as clean as possible a sample and therefore maximize its performance. The algorithm is composed of three modules: the image pre-processing, the feature extraction component and the Backpropagation Neural Network mod…
Two-view “cylindrical decomposition” of binary images
2001
This paper describes the discrete cylindrical algebraic decomposition (DCAD) construction along two orthogonal views of binary images. The combination of two information is used to avoid ambiguities for image recognition purposes. This algorithm associates an object connectivity graph to each connected component, allowing a complete description of the structuring information. Moreover, an easy and compact representation of the scene is achieved by using strings in a five letter alphabet. Examples on complex digital images are also provided. © 2001 Elsevier Science Inc.
Representing 2D Digital Objects
2000
The paper describes the combination a multi-views approach to represent connected components of 2D binary images. The approach is based on the Object Connectivity Graph (OCG), which is a sub-graph of the connectivity graph generated by the Discrete Cylindrical Algebraic Decomposition(DCAD) performed in the 2D discrete space. This construction allows us to find the number of connected components, to determine their connectivity degree, and to solve visibility problem. We show that the CAD construction, when performed on two orthogonal views, supply information to avoid ambiguities in the interpretation of each image component. The implementation of the algorithm is outlined and the computati…
Contract for the Supply of Digital Content
2014
The main aspects of a contract for the supply of digital content are analysed in this chapter. This can be seen as the most novel part of the proposed Regulation of the European Union, and is certainly a very important part of the final content of the proposal. This type of contract is a logical consequence of the development of information technology and communication, and the evolution of an information society and knowledge economy.
TRENDS IN THE DEVELOPMENT OF INTEGRATED MARKETING COMMUNICATION IN THE CONTEXT OF DIGITAL MARKETING
2019
Nowadays, in the context of digital marketing and social media development, with the advantages given by technologies and the vast possibilities of communication among consumers, businesses find the implementation of integrated marketing communication influenced by the Internet as a marketing communication environment where businesses are urged into a customer-centric approach by the consumers’ changing habits of receiving information. This results in an increased role of content marketing, relationship orientation, dialogue and network communication, management of multiple stakeholders etc., which envisages consumer involvement with a view to mitigating the consequences caused by the obsta…
Bibliometrics and Science Mapping of Digital Marketing
2021
This research paper focuses on marketing areas and specifically in the field of digital marketing. Marketing and other commercial endeavors are of the utmost importance for both companies and professionals in this field. The current research aims to determine how influencers persuade internauts in their consumption initiatives. Bibliometrics and science mapping are at the core of this study, and the yielded metrics highlight details that empower strategies and tactics in digital marketing. Thoroughly designed messages delivered by influencers can increase the visualization of companies enhancing their brands and positioning their products above the competence. Researchers can also use the p…
La evaluación de los materiales didácticos digitales
2017
Este artículo presenta los resultados más relevantes obtenidos a partir de un estudio centrado en analizar las características pedagógicas y tecnológicas de una muestra de materiales de repositorios y plataformas de contenidos educativos digitales actualmente existentes en España destinados a la Educación Primaria tanto de plataformas de contenidos educativos comerciales como de repositorios institucionales públicos. El artículo presenta inicialmente algunas refexiones sobre algunos de los principales aspectos que, en nuestra opinión, deben caracterizar la evaluación de los materiales didácticos en el contexto de la sociedad digital. La metodología empleada en el estudio consistió en el aná…
Detection of power line insulators on digital images with the use of laser spots
2019
The massive growth of technologies used to register and process digital images allow for their application in evaluating the technical condition of power lines. However, it is not possible without a set of dedicated methods for obtaining diagnostic information based on registered video data. The method described here details the detection of power line insulators in digital images featuring diversified backgrounds using laser spots. The algorithm of detecting an insulator in analysed images is based on testing the digital signal of pixel intensity profiles read between subsequent pairs of laser points in the image. The method is comprised of the following stages: import the image with laser…
Classification based on Iterative Object Symmetry Transform
2004
The paper shows an application of a new operator named the iterated object transform (IOT) for cell classification. The IOT has the ability to grasp the internal structure of a digital object and this feature can be usefully applied to discriminate structured images. This is the case of cells representing chondrocytes in bone tissue, giarda protozoan, and myeloid leukaemia. A tree classifier allows us to discriminate the three classes with a good accuracy.
On the Real-Time Simulation and Control of the Continuous Casting Process
1990
Ll this paper we present a method for controlling in real-time the secondary cooling of the continuous casting machine. The method is based on the heat transfer model, which simulates the temperature distribution of the cast, and on the use of direct digital control (DDC). Off-line simulation results considering the control method is presented.
