Abstract: An image encryption/decryption system performs quantification and reconstruction of 2-D and 3-D layered and arbitrary grayscale or binary images in raster or vector format and supports their secure transmission between a Sender and a Receiver. Quantification parameters of the images include Indices of Intrinsic Anisotropy of size (IIAsize) and structure (IIAstr), which reflect the image anisotropy with high sensitivity. The IIASTR and IIASIZE are used as hash values in authentication of a transmitted image. The system assures that the same set of transects which was used by the Sender in the image encryption will be used only by an authorized Receiver for decryption of the image.

Abstract: Parameterization of incremental patterns of various categories is provided by a computer system. The computer system initially undergoes filtering of the incremental patterns under study. Transects are plotted in a predetermined direction to growth incremental bands, and converted into an anisotropic structure in a 2-D domain. The width of the incremental bands along transects are calculated in combination with the area of incremental bands between neighboring transects. The structure of the incremental bands along with the width and area of the incremental hands across a 2-D plane for different levels of noise are calculated. Noise is reduced by averaging width and area across the 2-D plane. Indices of adequacy of the model and structural anisotropy of the incremental patterns are calculated.
