The article presents the method for implementation and results of examination of the Pan-Tompkins algorithm using a specialized 4-core Azurite processor, based on MIPS-II instruction set. The algorithm is used to determine heart rate on the basis of ECG signals. Azurite is a Multiprocessor System-on-Chip featuring an analog and a digital part. The digital part has been implemented in a Xilinx Virtex-6...
The main goal of this work is a presentation of a new algorithm dedicated to cysts detection in Optical Coherence Tomography (OCT) images. Considered in this paper OCT scans concern the eyeball examination in ophthalmology. The proposed approach utilizes different image processing techniques including non-linear complex diffusion and mathematical morphology operations and algorithms, in particular...
The Medical Cyber-Physical System (MCPS) for telemonitoring of pregnant women at home is introduced in the paper. The system comprises the Body Area Network (BAN) of advanced sensors that are interconnected on a body of a pregnant woman and the Personal Area Network (PAN) which is responsible for embedded processing of physical signals, smart alerts, and human-machine-interface. A reliable transmission...
The most important and primary aims of this article are two elements. The first one is a presentation of the feature vectors of the anterior and posterior cruciate ligaments of the knee joint and the second element is a discussion on the choice of the most effective features. In order to build the feature vectors, the extraction of the cruciate ligaments structures from the MRI images of the knee...
This paper presents the DMCSv1 multimodal bio-metric database collected by the authors. The database contains 3D face and hand scans acquired using the structured light technology. In parallel with this paper publication the DMCSv1 database is made publicly available for other research institutions. According to the authors' knowledge it is the first publicly available database where a hand was scanned...
The paper presents a Computer Aided Diagnosis (CAD) software for brain tumor detection and analysis from Magnetic Resonance Imaging (MRI). The software utilizes a novel multi-stage method that is capable of dealing with three main types of brain tumors, i.e. HG gliomas, metastases and meningiomas and yields object masks as well as quantitative parameters. The processing method makes use of several...
The authors developed the software tool with user's interface for designing the complete processing steps of ECG signal: from the filtering, through transformation and decision-making logic up to RR intervals analysis. The algorithm configuration function is replaced by the verification mechanism for R waves recognition efficiency. The program enables to download and process (in one or two-channel...
Psychological profiling is a necessary tool of modern human resource management, important for recruiting, placement and career planning. In extremely demanding jobs, like military service, the emerging problem is validity of psychological profile under stress-the problem is not only placement of people on adequate positions but also the limits of stress under which they remain efficient. We proposed...
The increasing demand for innovative systems, used for monitoring the biomedical parameters and comfortable for the patients, leads to the provision of better and better solutions. This paper presents the latest system design for the measurement of psychophysiological parameters for comprehensive use, developed at the Institute of Medical Technology and Equipment in Zabrze (ITAM), in light of previous...
The article presents the theme of stereoscopic images quality assessment. The first part of the paper describes the definition of stereoscopy and provides a preliminary discussion of the issue. The second part of the paper lists a set of commonly used metrics for the evaluation of 3D image divided into subjective and objective metrics, and these in turn, based on the analogical 2D metrics and metrics...
Stereoscopic films and interactive presentations are extensively popularized whereas their perceived quality still dissatisfies viewers. The reasons are shared between hardware inconsistencies and stereo image producers unawareness concerning factors influencing depth perception quality. This paper reviews aspects influencing 3D image perception visual comfort, presents visual comfort estimation methods...
The last few years in the movie industry were marked by continuous growth in the popularity of 3D technology. 3D movies are nowadays a major draw for both cinema and TV audiences. The application of 3D technology in combination with modern ultra high-definition video cameras causes that today's movies are more impressive and realistic. However, it also makes their production more and more complex,...
The paper presents a FPGA-based dedicated system for rapid calibration of 3D camera rigs. The developed device aims to help during camera set-up, by allowing the operator to easily compare the images from two cameras with use of several composition methods. The paper indicates the challenges related to development of high-throughput video processing systems in FPGA circuits. The processing methods...
Rapid evolution of the high-performance digital cameras entailed a development of new gigabit interfaces for video streaming and further image processing. A 25 megapixel camera, shooting with 100 frames per second, can easily produce a stream of data reaching tens of gigabits per second. The situation is more complex in case of image processing systems that acquire video stream from many cameras....
The production of stereoscopic motion pictures has been recently getting increasingly popular. To provide the best quality of the resulting image, the parameters controlled must precisely correspond to the values calculated by the stereoscopic image analysis platform or chosen by a camera operator. Currently no integrated system exists, which can provide remote monitoring and control of the parameters...
Together with the development of 3D technology, a growing demand for 3D content creation appeared, leading to a noticeable growth in both number of users and their requirements. Although, there are many commercial solutions that help to automate 3D video recording process, there is still a lot of room for improvements in this area. In this paper the design and implementation process of a mobile application...
Data acquisition systems must be capable to process all the data produced by the source to ensure the highest level of accuracy, especially when it deals with hard real-time system monitoring. However, the production of data is faster than the process to acquire and to process such a data. Using concurrency approach is an alternative to obtain the required level of performance and data processing...
New challenges are arising with the entrance in sub-100 nm CMOS nodes. Dominant sources of the MOSFET leakage which differ from those of previous nodes are examined. Consequences for the analog circuit design due to smaller dimensions and an accompanying higher variance of important analog parameters like threshold voltage in combination with shrinking VDD headroom are highlighted. As an example,...
