Paper Abstract

In this paper, the problem of automatic determination of the position and measuring the thickness of the human skin layers in high-frequency ultrasound images (HFUS) is solved. Location and the process of position determination of the skin layers are not an obvious process due to the phenomenological nature of the images received in HFUS, the so-called speckle noise and the lack of the objective measures. In order to determine the positions of the boundaries of the skin layers, the image analysis methods were used, based on the specific features of the HFUS images, such as layered structure and echogenicity features.

Only the fusion of the results of the analysis algorithms based on global (histogram of intensity levels) and local image features (cross-sectional and topological characteristics) improves discriminative features applicable to complete the information about the properties of the HFUS images with layered structure and to develop a method assessing the thickness of the skin layers. The knowledge gathered from such layers checks can improve understanding of the nature of the human skin and provide a more objective conditions for HFUS diagnostic imaging with speeding up the diagnostic process for dermatologists.

We proposed a new method for automatic segmentation on HFUS images using fusion of discriminative information based on nonlinear segmentation with a reasonable threshold setting, boundary selecting and linking, and false boundary point removing strategies for intensity distributions.
