Paper Abstract

A new method of low contrast image (LCI) analysis is presented. The method represents a generalization of the known Zernike's method of phase-contrast imaging (ZMPCI), because it covers a wide class of LCI. From the other hand, the new method is further development of the ZMPCI, because it is based on using a new phase-space information characteristics and ensures more sensitive and detailed LCI analysis. The method is completely digital and any analog operations are not needed. It allows to obtain an effect which is equivalent to focus depth variation. From mathematical point of view, the method belongs to domain of nonlinear image processing. Results of experimental investigations are presented.
