Research projects

Multimedia Systems Department participates in many research projects, both European projects and the ones funded by Polish Ministry of Science and Education and other Polish institutions.

Polish projects - ongoing

IDENT – Multimodal, biometric system for verification of bank client identity. The aim of the project is to develop a technology for automatic identity verification, resulting in high accuracy of the verification and increased efficiency of client verification systems. The project assumes developing a multimodal system, consisting of the hardware layer and a specialized software for data acquisition from various sensors, data processing and fusion, leading to a reliable verification of a bank client. The developed technology will be validated on a group of 10 000 persons.

HCIBRAIN – methods of human-machine interaction for diagnosis and stimulation of patients with severe brain damages. The project aims to develop an integrated multimodal system for stimulation of patients with brain damage, and for recording ABR, EEG and ERP signals, as well as gaze tracking. A validated procedure for diagnosis and polysensorial cognitive therapy will be developed, constituting an efficient and widely available approach to diagnosis and rehabilitation of patients who are unable to communicate, mainly those in coma. Six specialized medical centers will take part in evaluation of the developed prototype.

INPREDO – the main aim of the project is to develop an intelligent system for determining the optimal traffic speed limits. A set of tools will be developed for providing guidelines on the allowed traffic speed depending on various conditions. Detailed recommendations concerning criteria and procedures of setting traffic speed limits will also be created. An additional aim is to create Dynamic Maps showing the current state of roads, including the traffic density and the determined speed limits.

ALOFON – the project aims to develop a methodology of an automatic phonetic transcription of English speech, based on the analysis of audio and video. Relationships between the allophonic differentiation in speech and the objective signal parameters, will be researched. The project assumes that a method for detection of small differences in the allophones and accent, will be developed. The automated phonetic transcription method will be used in many solutions, including English language learning (especially in the remote learning), phonetic and phonologic research (language corpora processing), automatic accent recognition, etc.

European projects - finished

COPCAMS (COgnitive & Perceptive CAMeraS) - ARTEMIS project funded under grant agreement No. 332913 (2013-2016). The project consortium consists of 21 partners from seven European countries. COPCAMS leverages recent advances in embedded computing platforms to develop large-scale, integrated vision systems. It aims to exploit new programmable accelerators, particularly many-cores, to power a new generation of greener, low-power smart cameras and gateways. This will be possible owing to a paradigm change: whereas previous generation of systems had simple cameras connected to powerful centralised computing servers through high-bandwidth networking, the COCPAMS vision is to push low-power, high-performance computing on the edge of the system and in the distributed aggregators. These “smart cameras” and “smart aggregators” will process video streams, extract significant semantic information and decide locally whether or not the streams’ content is of interest and is worth propagating. The decentralised, distributed decision-making will save both energy and bandwidth, while opening up opportunities for new distributed applications.

ADDPRIV (Automatic Data relevancy Discrimination for a PRIVacy-sensitive video surveillance) – the project seeks to improve public safety by ensuring the individuals' privacy right, enriching the current video surveillance systems through an automatic discrimination of relevant data recorded. The project addresses the challenge of determining through an automatic, accurate and reliable manner which information obtained from a distributed system of surveillance cameras is relevant from the security perspective and which is not, and can be safely deleted. This will limit unnecessary data storage and will protect the citizens’ privacy right. ADDPRIV proposes novel knowledge and developments to limit the storage of unnecessary data throughout existing multicamera networks in order for them to better comply with citizen's privacy rights. ADDPRIV addresses the challenge of determining in a precise and reliable manner private data captured by video surveillance systems that are not relevant from a security perspective. ADDPRIV proposes solutions for automatic discrimination of relevant data recorded on a multicamera network, related to an individual whose suspicious behavior triggered an alert. Relevant data not only corresponds to video scenes capturing individuals' suspicious behavior (smart video surveillance), but also automatically extracting images on these individuals recorded before and after the suspicious event and across the surveillance network.
