    Opis:
    The paper presents the circular Hough transform in the process of detecting and counting coins. The issues of linear and circular Hough transform are discussed. An algorithm for counting coins in a three-dimensional image using the discrete Hough space is demonstrated. Moreover, the results of the application for detecting and counting coins in a static image and video stream are presented. Observations of histograms for HSV and RGB color palettes, for different camera resolutions and various parameters of image segmentation, edge detection and smoothing filter have been made.

    Opis:
    This work presents the method of leaks detection in recorded sequence of infrared images. Infrared field measurements were taken on small experimental embankment during flood process simulation. The leak processes took place thru initially dry facility. Getting wet areas were visible in infrared images as lower temperatures part of embankment on its air side. Image processing methods allowed to localize the leak in thermal images, despite the impact of external factors on the measurement and differences in objects emissivity in the observed scene.

    Opis:
    The important role of coal in the global energy sector is unquestionable. Improving the efficiency of extraction of raw materials is one of the main tasks of which are committed to designers of modern mining machines. Therefore, you have increasing importance in the process of mining have support systems trouble-free operation of mining machines. At the KOMAG Institute of Mining Technology diagnostic system has been developed combine with the use of thermal imaging techniques. This is the first in the world this type of solution dedicated to working underground mines potentially explosive methane and / or coal dust. The article presents the results of prototype tests combine diagnostic system using a thermal imaging camera realized on a real object in the mine. They pointed out the advantages and disadvantages developed solutions and formulated appropriate proposals summarizing.

    Opis:
    This paper demonstrates the application of different image processing techniques to process high resolution visual images and merge it with low resolution thermograms to improve its level of detail. The same idea is applied in commercially available thermal cameras (e.g. FLIR with MSX® technology). Low resolution thermograms considered in this paper were obtained from a thermal scanner with point infrared detector (Fig. 1) sensitive to long wavelength infrared spectral range. The proposed algorithms are Laplacian, Sobel operator, embossing and Gaussian differential blur (described in section 3). The authors processed 6 different thermograms to qualitatively assess obtained results. It was done in a statistical manner through a survey and revealed that both Sobel operator and embossing provided the most clear, detailed and unambiguous results (Fig. 5). Such algorithms may be applied for processing more channels in a multispectral, cost-effective system.

    Opis:
    The article presents automatic eye corners detection algorithms in thermal images. Its target application is to perform quick and unnoticed measurement of human body temperature. It is proved that the temperature of eyes’ corners is the most reliable and stable temperature considering infrared imaging. That measurements were done manually so far. Our approach is to do this automatically and create complete system for measurement of core human body temperature in crowded places where it is impossible to do this in another way (for example on the airport, railway station). Such system could prevent people for spreading off the epidemic. Two proposed algorithms are presented: first based on morphological operations and geometric features of human face, second based on the cross-correlation and idea of pattern tracking. The selection of appropriate ROI size for reliable temperature extraction was tested according to the distance to person under observation.
