The Analysis of Properties of Schlieren Color Images

Contribution treats the topic of experimental analysis of statistical properties of intensity images of red, green, blue component and grey-scale representation of color image of visualized optically transparent polymeric foil by means of schlieren method. As the subject of the analysis were corrected intensity images of RGB components and grayscale representation of color image of visualized foil. Properties of mean value and standard deviation of color components intensity levels and grayscale images for selected samples of 5 types of polymeric foils were studied. The analysis shows effect of the choice of color component. Characteristics calculated from the intensity image of blue component color image proved the best properties. Such a fact can be used in the case of defectoscopy and the foil recognition by the use of methodology of processing and statistical analysis of images visualized optical transparent polymeric foils captured by the color cameras.
