摘要

The hybrid technology of chest roentgenogram classification, based on three-level hierarchic structure, has been suggested. "Weak classifiers," based on two ways of data analysis, are formed on the first level. The approach is to make a "weak" classifier using the first way which is based on the analysis of Fourier amplitude spectra in sliding window. An X-ray image is sequentially scanned by windows of various scales. A "weak" classifier is made based on Fourier amplitude spectrum, defined in each window. It refers to an image segment, which got into the sliding window, to a certain class. The second way of making a "weak" classifier is based on the descriptors, which were received because of intensity histogram approximation in the analysis window. The number of received "weak classifiers," based on the two ways of analysis, depends on the number of analysis window scales chosen. On the second hierarchic level, the solutions of "weak" classifiers within every way of the first hierarchic-level analysis are integrated. A final classifier makes the ultimate solution, which aggregates the solutions of two second hierarchical level classifiers.
