The aim of the article is to investigate the influence of the pressure of the measuring probe on human tissues during spectrophotometric measurements. The effect of reflection probe pressure on human skin spectra in the different points of left and right hands was observed in the range of 400 – 1000 nm. The analysis was performed for different pressure values applied and probe impact time intervals elapsed.
The article is devoted to the development and justification of parallel numerical simulation methods. Results can be obtained to calculate the number of points. To increase the order of approximation of the developed methods, the set of points of the reference block (s) is introduced into difference schemes. Generation of difference schemes for any reference and calculated points is considered. For some block sizes, generated differential calculation schemes are obtained, oriented to the number of available processes in a parallel implementation. The absolute stability of the constructed multi-step multipoint methods according to the initial conditions and the right side is proved.
Malignant melanoma is one of the fastest-spreading skin cancer. The aim of the article is to segment human skin lesions with malignant melanoma from clinical dermatoscopic images and quality analysis images after segmentation. In this work the segmentation by thresholding with tree different threshold values was used. The quality analysis of the created binary images was carried out in Matlab software, based on statistics generated after image segmentation. The created segmentation algorithm allows the analysis of a single skin lesion, shows three areas of skin lesions based on their color.
