Abstract
A method of classifying terrain, terrain activity and materials through panchromatic imagery a module programmed to provide such classification and aerospace vehicles comprising such module is provided. Panchromatic images of known materials terrains and terrain activities are taken and processed to form a multiband texture cube, that due it amount of data, is stored as a computer data base. New panchromatic images of unclassified materials, terrains and/or terrain activities are processed and compared via computer with such database that allows for inexpensive, quick and efficient classification of such new images.
Claims11
A method for identifying terrain, terrain activity and/or materials, said method comprising:
- a) comparing one or more panchromatic images that have been processed as follows:
- (i) resizing dimensions of said one or more panchromatic images to establish a scale for each panchromatic image;
- (ii) adjusting a pixel scale of said one or more panchromatic images;
- (iii) filtering at least one of said one or more panchromatic images through a Fourier frequency isolation filter and/or a statistically derived Haralick texture measurement filter, said filters being tuned to different spatial windows and frequencies, said filtering generating a set of multiple images;
- (iv) combining the set of multiple images to form a multiband texture cube assembly for the set of images, the multiband texture cube assembly having multiple new bands;
- (v) normalizing the multiband texture cube assembly;
- (vi) reordering and labeling the multiple new bands to match a library or reference database format or a band sequence;
- with an image database that comprises images that have been processed in the same manner as said one or more panchromatic images;
- b) using said comparison to identify one or more terrains, terrain activities and/or materials contained in one or more images of said panchromatic images.
