FIELD AND GRANT DESCRIPTION
Study of emotional facial expression recognition represents an advanced research topic in the fields of affective computing and human-computer interaction. It is important to improve the emotion intelligence of the machine and to implement an affective human-machine communication.
However, current researches over the emotional facial expression recognition are usually limited to
simple environments, thus cannot be successfully applied in human-computer interaction. Aiming at the above limits and considering the requirements for robust and automatic emotional facial expression recognition in real life, this project proposes the study of emotional facial expression recognition in complicated environment.
ACTIVITIES AND RESULTS
Activities for 2010:
Several major face imagery processing topics have been addressed, e.g.:
- an overview of the current state of the art systems/algorithms/methodology was performed;
- data acquisition: some of the experiments were performed using Beihang University facial expression database and with images acquired from real environments with complex backgrounds, large variety of emotional states, occlusions;
- preprocessing: we have employed robust techniques for mean shift segmentation, background estimation, tracking;
- feature extraction: a novel method for facial expression recognition which is robust to facial occlusion has been proposed. The face to be recognized is reconstructed using robust principal component analysis (RPCA), and saliency detection is used on the difference image of reconstructed face and the face to be recognized to obtain the facial occlusion region. For improving the nonlinear alignment performance of Active Appearance Models (AAM), we apply a nonlinear manifold learning algorithm, Local Linear Embedded, to model shape-texture manifold.
- classification: some possibilities regarding the use of novel neural architectures (e.g. Liquid State Machine) for processing the facial expression have been analyzed. Also a reweighted AdaBoost classifier has shown good results with respect some public databases of faces, e.g. JAFFE;
- optimization: we have been proposed the application of the Pattern Search Optimization for feature extraction and classification parameters;
- face expression synthesis: novel model of layered fuzzy facial expression generation has been proposed. A novel layered fuzzy facial expression generation language is also developed for conveniently controlling facial expression generation of virtual agent.
According the initial activities plan, four Chinese researchers had visited Romania between 23 - 30 June, 2009. Mission of the four Romanian researchers in P. R. China took place between 27 April – 06 Mai, 2010.

FIELD AND GRANT DESCRIPTION Making decisions is a branch of artificial intelligence that is more and more used in complex applications like medicine (using a diagnostic, a treatment decision is made), geology (using images of a region, some hypotheses regarding the underground composition and some decision about extraction are made) or communications (using information about the functioning of each element of a communication network, some decisions about the resources allocation are made, for example of
the frequency bandwidth). According to Bob Colwell, any machine can have artificial intelligence. This must be developed on the basis of understanding and imitation of the human brain.
The intelligence results from the action of a large group of specialized neurons that use a world model based on memory to make a continuous series of predictions of future events. The neural networks of the cortex must be interpreted like a distributed memory of pattern sequences stoked in an invariant form, hierarchically arranged, accessed in an associative fashion. Between the neural network applications already known we can find applications in decision making for medicine, geology and communications. To make a correct decision, the decider must have the information in an appropriate form. This is the reason why, alternative representations of information are frequently used. A very interesting representation is in this respect the wavelet decomposition. In this project we want to associate the wavelets theory with the neural network theory to solve problems of decisions making in medicine, in geology and in communications.

Assoc.rof.dr.eng. Cătălin CĂLEANU Teach assist. dr. eng. Ciprian DAVID Teach assist. eng. Gheorghe POPA Dr.eng. Georgiana SIMION FIELD AND GRANT DESCRIPTION
Probabilistically oriented approaches for image sequence analysis have difficulties in modeling complex situation encountered in real world applications. To alleviate this problem, we propose a new theoretical framework for fusing the
statistical thinking level with the semantical level in the benefit of both. We will test the effectivenes of the concept on object tracking and motion estimation tasks, related to human body motion analysis. We define three main research objectives.
The first one is the development of a semantically guided kernel traker. The best method to exploit semantic information extracted from the iamge sequence through inference in the traking performance improvement will be investigated. Our second research objective is to find effective use of the new sparse representation in motion modeling and semantic inference. The third research objective is to enhance a foreground/background segmenter by higher level information extracted from the processed image sequence.
ACTIVITIES AND RESULTS Development of a semantically guided tracker Robust background estimation

IBCI – Institute for Cardiovascular Diseases Iasi
FIELD AND GRANT DESCRIPTION:
Cardiovascular affections are a prime cause of mortality and morbidity in Romania. The risk of cardiovascular morbidity and mortality remains high despite the attempts of correcting the cardiovascular risk factors. In the field of cardiovascular pathology the death risk by cardiovascular or vascular-cerebral accident persists even after the patients have left the hospital.
Monitoring the health condition of these and the analysis of evolution trends of the biophysical and biochemical parameters represents an essential prevention factor.
The project envisages research, design and implementation of a flexible and self-adapting system for the monitoring of biological signals.
Research and design activities will be oriented towards developing a system architecture and organization for remote monitoring and creating the interfaces for acquisition, monitoring and remote transmission to a hospital unit (hub). The signals acquired from the patient include: heart bio- potentials, blood pressure, blood O2 concentration, heart and breath rate, temperature, blood glucose concentration etc. The mobile computing equipments (MCE) integrated in the systems will be: Personal Digital Assistant (PDA), and/or „smart phones” (mobile phones MP).
The project will use hard – and software platforms (PDA and MP) of broad usability, which correspond to the requirements of the application in terms of computing power and also by their low price. Based on intelligent interfaces that will be designed, the system will automatically integrate the sensors in „plug & play” mode and also adapt its communication strategy with the hub/dispatcher for cost minimization and for ensuring the reliability and availability of the data link. It cannot be neglected, that this system development strategy will offer high versatility and scalability and will allow for expanding project results beyond the field of remote medicine.
The project will develop and integrate two categories of intelligent interfaces: 1. specific to signal acquisition from sensors placed on the patient and 2. communication – dedicated (by wire or wireless) necessary for warning/alert messages transfer and also for data transfer to the hospital hub. Remote data-transmission will allow for communication technologies, like: Near Field Communication (RFID, ZigBee, RuBee, Bluetooth), remote wireless: GSM/GPRS, EDGE, UMTS, Wi-Fi, WiMax as well as the wire based ISDN and Ethernet.
The project is relevant to research direction ―1 – Information and communication Technology‖, theme priority: “1.6. Technologies for distributed systems and embedded systems‖, aimed at developing of new technologies for integrated systems based on biomedical sensors networks (specific objective 1.6.14). The project objectives envisage also the development of applications for communication and computing embedded systems (specific objectives 1.6.17 and 1.16.16) ensuring local data processing and transmission to the hospital hub.
The purpose is to develop new technologies for integrated systems based on intelligent sensor networks for monitoring biological signals, remote transmission and processing for prevention and diagnosis. Envisaged are both theory development of architecture and organization of the systems for intelligent sensor networks (wire based or wireless) as well as practical implementation and testing of the mobile monitoring system carried by the patient. The proposal has innovative characteristics:
the architecture and organization; the „plug&play”
interfaces in compliance with the IEEE 1451 standard; the integration based on widespread platforms (PDA, MP); processing, analysis and detection of alerts using also „artificial intelligence”
methods, development of strategies allowing for high reliability of the data link with the hospital hub, all these are characteristics of a modern and extremely useful solution for the developments in the field of bioengineering. The project will create the conditions for radically improved material bases required for the monitoring of the main biological parameters of the patient in the ambulatory which will increase the efficiency of the medical art, especially prevention, reduce the costs of medical assistance and extend the experimental base, very necessary in the field. Also, the formative component, especially by integrating young researchers in a field with real prospects contributes to the relevance of the project.
