    Abstract
    In this paper the extraction of anthropometric parameters is presented. Such extraction is focused on two main areas – visual and non-visual. The first presumes the utilization of image processing algorithms and is working primary with the single image, both calibrated and uncalibrated image is considered. The latter presumes the design and deployment of a hardware prototype for the measurement of anthropometric parameters. The greatest advantage being the accuracy of extracted parameters that may be further used for comparison with the visual approach. The partial results of the researches are presented and future goals are following the outputs of the prior works creating the overall framework for the extraction of these parameters having as a main goal the smallest error in the measurement process.

    Abstract
    In this paper a novel methodology for estimation of parameters from real-world scene in multi camera environment is presented. Specific focus is put on the estimation of parameters from human body, i.e. focal point is the field of anthropometry and its application in the computer vision. We utilize and employ known proportions of human body in our system. Based on several of such parameters and together with the output of the multi-camera system we approximate several of human body parameters. Deployment of complementary object with known dimensions is to enhance the final calculations. This object is created based on 3D computational model and thus further mapping of 3D model to 2D scene is possible. Final solution may help in several use case scenarios, e.g. complementary aid in human recognition or replacement of measurements for statistical purposes.

    Abstract
    Traditionally, the estimation of object’s real dimensions in the field of computer vision requires utilization of two cameras or calibration of a single camera in a static environment. In this poster, the novel approach for measuring the object’s real dimensions from the single camera is presented. Prior to meas-urement itself, some specific conditions have to be met and several image pro-cessing algorithms are being utilized. The first essential condition is the infor-mation about camera’s height from the reference plane. Next, two images are re-quired in order to subtract the background while keeping the object, the first with the object of interest and the second without, both presume to be taken under the same conditions. The output image containing solely the object of interest is then processed using Canny edge detector and the selection of the object itself is done by bound box or bounding circle. Software solution is built on OpenCV library. The width and the height of the object is obtained following the created reference model based on the linear equations that were established as a result of testing. Separate tests were carried out for both, the width and the height. The final set of equations follow the basic trigonometric rules and are separate for both dimen-sions. Several experimental procedures with various objects being in a diverse heights proved the accuracy of the measurements to be higher than 90 percent.

    Abstract
    In this paper, the adaptive web-based system for examination with cheating prevention mechanism is presented. The idea of system was created based on the need to provide impartial evaluation during testing of learners – statistics of cheating during exams from the last decade is rather alarming however not surprising. With the dawn of new technologies cheating is becoming much easier than it used to be, as a natural result certain anti-cheating mechanism has to be deployed. System itself is in nature web-based and thus enables easy and widespread access. Approaches that enable automatic monitoring of learner during an examination were following and enhancing those in previously created systems. As a communication technology over the internet or intranet was utilized WebRTC which enabled to incorporate together various live monitoring capabilities – video, audio, screen of computer. Another feature that is in the center of interest is adaptive selection of questions. This selection is automatically carried out by system and it is based on answers as provided by learner. Deployment in the real environment is expected to be used as a complement that is to enhance education quality and provide automatic impartial evaluation of learner.

Presented approach may be used for multiple purposes. Principal and primary purpose is to monitor attendance, which is possible thanks to university database. When implemented, system is expected to evaluate the attendance automatically or if necessary using collaborative authentication. Non-standard or anomaly detection is another feature that is to be provided by system, subject to tracking are hands, eyes and movement.

    Abstract
    Paper describes the design of extended model for tracking and locating object inmulti-cameras environment with controlling the streams from multiple angles in real time. Proposed and experimentally implemented solution is attempting to deliver via streaming technology of the only specific shot from scene that has the best view on tracked object in real time. Measurement of the best shot for the tracking object is based on proposed evaluation metric, consisting of dimensional, locational and reliability parameters gathered from object tracking methods. For latency optimization and accuracy of evaluation the prediction of evaluation metric was outlined. Solution is experimentally tested in standard and mobile environment as well. Approach described in this paper is innovative regarding the content related video stream delivery.

    Abstract
    This paper represent an approach of applying the graphical visualization methods to the educational process. The Virtual electrotechnologic factory is created based on theory and contains the theory itself. The technology utilized during the process of the development was the Flash multimedia platform. This allowed us to visualize all the theoretical processes, logically connect them and link them with other multimedia content such as animations, video, still images or audio. Moreover factory was created in two language versions and possibility of offline and online usage is available. Virtually all the content is loaded into the factory from external folders and thus allows easy editing without the need to access the Flash source files.

    Abstract
    This paper presents a new approach to use of the animations as a tool for education. Our approach is focused on the methodology of designing the animation rather than on the study whether it is or is not beneficial in the educational process. We will introduce the animation as a tool, present commonly used tools for development and then introduce a basic technique for developing an animation. Education is the most powerful mean to improve the understanding and the ability to perceive the world, therefore its resources should be used wisely.
