After basic frequency-based analysis and segmentation for high speed videosequences containing motion information, it is necessary to remove some of the motion artifacts distorting the results for accurate analysis. In the paper we are describing construction of amplitude and phase maps based on FFT and projecting 3D image information (videosequence) to relevant 2D arrays. Synthesis of these maps...
This paper describe shortly our work by proposal of lighting unit for video workstation for medical analysis. The workstation is a part of cooperation between our department and medical faculty and faculty hospital in Martin (Slovakia). In paper describe the basic conditions for the our design of lighting unit and their control. We focus on LED optical source and possibility of using in our application.
This paper focuses on software designed for high speed video acquisition system and biomedical image enhancement. The software is used for image acquiring thru digital camera, intelligent illumination dimming hardware control and ROI statistic creation. All software parts are realized as virtual instruments in LabVIEW. The other advantage of designed software is possibility of manual and automatic...
This paper provides information about device for overhead contact line height and stagger measurement. This device was developed in Department of mechatronics and electronics, University of Žilina in collaboration with Railways Researched and Developed Institute in Vrútky. The device is determined for overhead contact line continuous measurement. The based measured parameters are overhead contact...
This paper focuses on high speed video acquisition system designing for biomedical image enhancement. The paper gives information about microscope dimmer using in image analysis. Due to fast digital camera, system contains intelligent illumination dimming hardware automatically regulated through measurement card. Regulating parameter for dimmer (PWM duty cycle) is computed from image features, histogram...
Virtual instrumentation is defined as the combination of measurement and control hardware and application software with industry-standard computer technology to create user-defined instrumentation systems. Computer-aided laboratory exercises based on the LabVIEW system are efficiently used on the topic of power electronic systems. The paper presents the application mentioned virtual instrument system...
