The article deals with imageprocessingalgorithms in the analysis plane of an angle measuring two-axis autocollimator, which uses a reflector in the form of a quadrangular pyramid. This algorithm uses Hough transform and the method of weighted summation. The proposed algorithm can reduce the area of nonoperability and open up new possibilities for this class of devices.

We present an LCD with independently controllable RGBW backlight emitters, and novel backlight control and imageprocessingalgorithms. For each input frame of video content, the minimum RGBW power combination required to display the content with maximal colour gamut, and modified image data to accurately reproduce the intended colours under new illumination, are calculated in real time, using the existing graphics processing hardware in a commercially available Android tablet.

When a marine target is detected by a mid-infrared detector on a sunny day, the target's information could be lost if it is located in sun glint. Therefore, we developed a new mid-infrared imaging system capable of effectively detecting marine targets in regions of strong sun glint, which is presented in this report. Firstly, the theory of the analysis methods employed in different detection scenarios is briefly described to establish whether one or two polarizers should be utilized to suppress further the p-polarized component of sun glint. Secondly, for the case in which a second polarizer is employed, the formula for the optimum angle between the two polarizers is given. Then, the results of our field experiment are presented, demonstrating that the developed system can significantly reduce sun glint and can enhance the contrast of target images. A commonly used imageprocessing algorithm proved capable of identifying a target in sun glint, confirming the effectiveness of our proposed mid-infrared polarization imaging system.
