Chapter
The automatic crash-landing of a fixed-wing UAV is challenging due to high velocity of approaching aircraft, limited manoeuvrability, lack of ability to hover and low quality of textural features in common landing sites. Available algorithms for ground plane estimation are designed for automatic cars, robots, and other land-bound platforms, where t...
Chapter
This article proposes the system designed for automatic detection of emergency landing sites for horizontally landing unmanned aerial vehicles (UAV). The presented solution combines the classic computer vision algorithms and novel segmentation methods based on deep learning techniques using the U-Net inspired network architecture. The presented sys...
Chapter
The latest animated films from major studios, such as Pixar and Disney, make a great impression, but not everyone is aware that the production process of such films absorbs the work of hundreds of specialists, and their budgets often exceed hundreds of millions of dollars. The way of creating these films has not changed for decades, and the quality...
Chapter
By using clothing with built-in biomedical sensors, the acquiring chosen parameters directly from the patient’s body is available without a special and tiresome installation and calibration. The publication presents the stage of the design process of wearable element for vital parameters measurement system. The system is designed for use especially...
Chapter
Wearable systems with biomedical sensors have diagnostic, as well as monitoring applications. Parameters extracted from physiological measures in everyday situations can provide indicators of health status and can have diagnostic value, especially for cardiology telemedicine. The publication presents the review of reconfigurable, wearable or possib...

Introduction: Deficits in area of communication, crucial for maintaining proper social bonds, may have a prominent adverse impact on quality of life in patients with schizophrenia. Social exclusion, lack of employment and deterioration of family life, may be consequences of aggravated social competencies, caused by inability to properly exhibit an...
Conference Paper
Unmanned aerial vehicles are becoming popular, but their autonomous operation is constrained by their collision avoidance ability in high-velocity movement. We propose a simple collision avoidance scheme for fast, business-grade fixed-wing aircraft which is based on optical flow and stereovision. We calculate optical flow on parts of the image that...
Article
Background: Virtual reality exposure therapy (VRET) is becoming a more and more popular treatment method for patients suffering from anxiety disorders. One of the VRET methods, wchich could be used for this group of patients is MOTEK CAREN system, however, so far no studies have been published on its implementation in psychiatric disorders. Subje...
Conference Paper
Facial expression reconstruction is an important issue in the field of computer graphics. While it is relatively easy to create an animation based on meshes constructed through video recordings, this kind of high-quality data is often not transferred to another model because of lack of intermediary, anthropometry-based way to do so. However, if a h...
Conference Paper
The paper describes an approach for selection of feature points on three-dimensional, triangle mesh obtained using various techniques from several video footages. This approach has a dual purpose. First, it allows to minimize the data stored for the purpose of facial animation, so that instead of storing position of each vertex in each frame, one c...

The poster presents main ideas of advanced motion analysis and synthesis laboratories, cluster infrastructure, datasets and software in shareconomy model.
Conference Paper
Parts of a joint anatomy, such as bones or the joint center can be robustly identified in an ultrasound image with the help of an articulated or structural model. Such a model is a structure of parts that represent the bones and skin as polygonal chains and the join as a point, where the parts remain within specified geometric relations. The parts...
Chapter
The article presents the Living Labs for Human Motion Analysis and Synthesis (LivMASS), which is a shareconomy resource. It is intended to integrate local and geographically distributed stakeholders. The current resources and potential of LivMASS are described, including its laboratories, research activities, specific projects, collaborations and t...
Conference Paper
Growing importance and commonness of video surveillance systems brings new possibilities in the area of crime suspect identification. While suspects can be recognized on video recordings, it is often a difficult task, because in most cases parts of suspect’s face are occluded. Even if there are multiple cameras, and the recordings are long enough t...
Conference Paper
The paper presents the concept and implementation of distributed group collaboration tool intended for collective diagnosing of Parkinson Disease (PD). Collaborative decisions as a result of experts meetings and discussions on many clinical cases and many assessment methods, by geographically distributed domain experts seem to be more reliable opti...
Conference Paper
Marker-based performance capture is a technique that enables acquisition of expression and mimicry of human face. This data can be used to propel facial animation system, be it bone driven or similarly dependant on position of points in space. Every model that is to be animated has to be analyzed in order to select level of influence each marker ha...

Shareconomy is a peer-to-peer model including non-profits, government, corporations and individuals, with shared access to resources and services which optimizes their utilization. The Polish-Japanese Academy of Information Technology (PJAIT) conducts research and development in information and communications technology (ICT) specializing in Artificial Intelligence, Bioinformatics, Social Informatics, Computer Graphics, Image and Video Processing and Human Motion Analysis and Synthesis. During the last five years, at the Research and Development Center of PJAIT in Bytom, Poland evolved a concept of motion analysis and synthesis labs in shareconomy model. In this period of time, four advanced research laboratories: Human Motion Lab (HML), Human Microexpression Lab (HMX), Human Seeing Lab (HSL) focused on video and image analysis, Human Facial Modeling Lab (HFML) have been created with the help of using EU and national grants. Also, two more have been formed: Human Dynamics and Multimodal Interaction Lab (HDMI), and Wearable Technology Lab (WTL) to study motor control, performing movement analysis in real-time, with immediate feedback to both experts and patients. The Living Labs for Human Motion Analysis and Synthesis is a shareconomy model integrating local and geographically distributed stakeholders, enabling collaborative research and innovations in human motion analysis and synthesis. All resources from Research and Development Center PJAIT in Bytom, Poland are elements of an ecosystem capable of supporting advanced research activities remotely and efficient utilization of research and development resources in shareconomy model. A telepresence infrastructure is used to support research activities across Poland, within the Pionier Network and in Europe within the GEANT Network. The funding resources and planned funding strategies include targeted programs for research based on a LivMASS network, a communication campaign, and programs to foster networking and the inclusion of SMEs, universities, medical institutions and other prospective stakeholders. http://bytom.pjwstk.edu.pl
