Modelling a Deep Learning Framework for recognition of human actions on video
Santos, Flávio; Durães, Dalila; Marcondes, Francisco; Gomes, Marco; Gonçalves, Filipe; Fonseca, Joaquim; Wingbermuehle, Jochen; Machado, José ManuelIn Human action recognition, the identification of actions is a system that can detect human activities. The types of human activity are classified into four different categories, depending on the complexity of the steps and the number of body parts involved in the action, namely gestures, actions, interactions, and activities [1]. It is challenging for video Human action recognition to capture useful and discr...
Detection violent behaviors: A survey
Durães, Dalila; Marcondes, Francisco Supino; Gonçalves, Filipe Manuel; Fonseca, Joaquim; Machado, José Manuel; Novais, PauloViolence detection behavior is a particular problem regarding the great problem action recognition. In recent years, the detection and recognition of violence has been studied for several applications, namely in surveillance. In this paper, we conducted a recent systematic review of the literature on this subject, covering a selection of various researched papers. The selected works were classified into three m...
In-vehicle violence detection in carpooling: A brief survey towards a general s...
Marcondes, Francisco S.; Durães, Dalila; Gonçalves, Filipe Manuel; Fonseca, Joaquim; Machado, José Manuel; Novais, PauloViolence is a word that encompasses several meanings ranging from an actual fight to theft and several types of harassment. Therefore, violence detection through surveillance systems can be a quite difficult yet important task. The increasing use of carpooling services and vehicle sharing brought the need to implement a sufficient general surveillance system for monitoring these vehicles for assuring the passen...
Review of trends in automatic human activity recognition in vehicle based in sy...
Coimbra, Ana Cecília Sousa Rocha; Neto, Cristiana Marisa Pereira; Ferreira, Diana; Duarte, Júlio Miguel Marques; Oliveira, Daniela Sofia RijoDriverless vehicles are more and more becoming a reality. However, people still have some concerns in using them, the main concern is fear, hence the importance of creating a surveillance system inside those vehicles. For the detection and classification of human movements to be possible it is necessary to train the system with data representative enough for all kinds of possibilities. Although the production o...
Review of trends in automatic human activity recognition using synthetic audio-...
Jesus, Tiago Rafael Andrade; Duarte, Júlio Miguel Marques; Ferreira, Diana; Durães, Dalila; Marcondes, Francisco Supino; Santos, Flávio Arthur OliveiraAn in-depth study of knowledge and technologies was made related to the various scientific, technical, and industrial domains necessary for the acquisition of skills and capabilities for the design and development of a multisensory fusion system for vehicle cockpits. After an extensive literature review, it was possible to determine the baselines of the solution to be developed and obtain a pipeline prototype.

MS prevalence and patients’ characteristics in the district of Braga, Portugal
Figueiredo, José; Silva, Ângela; Cerqueira, João José; Fonseca, Joaquim; Pereira, Paulo A.Multiple Sclerosis (MS) is a chronic autoimmune disease of the Central Nervous System causing inflammation and neurodegeneration. There are only 3 epidemiological studies in Portugal, 2 in the Centre and 1 in the North, and there is the need to further study MS epidemiology in this country. The objective of this work is to contribute to the MS epidemiological knowledge in Portugal, describing the patients’ epid...
Sintaxe, semântica e pragmática das comparações emblemáticas e estruturas apare...
Fonseca, JoaquimThe author studies the syntagmatic, semantic and pragmatic properties which characterize the configuration and functioning of a type of emphatic comparison known as emblematic or polar comparison (e.g. alto como uma torre; branco + frio + puro como a neve). Such comparisons are also seen as the root of different formal solutions which are projected in speech, involving specific mechanisms of production and inte...
Coerência do texto
Fonseca, JoaquimThe author characterizes the notion of coherence as a property of all verbal products which involve the combination of elements (from the syntagma to the text) and stresses that such a property reveals the cognitive, exterior dimensions which are not, however, foreign to the functioning of natural languages. The author underlines the non-idiomatic importance of coherence: this is particularly visible on the lev...
Heterogeneidade na língua e no discurso
Fonseca, JoaquimThe author characterizes the heterogenity in semiotic systems in general and in natural languages in particular, distinguishing two basic types. The article then goes on to survey the most apparent moments and modalities of each of these types of heterogenity in both the structure of language and of discourse.
