Abstract
A method for analysis of a two-dimensional image. The two-dimensional image is scanned to form a digital bit-map of X-Y axis locations in the image. Gray-scale densities are measured at each of the locations, and are used to calculate third, Z-axis values. The X-Y-Z axis coordinates are plotted so as to form a virtual three-dimensional image having a contour that corresponds to variations in the gray-scale density in the two-dimensional source image. The virtual three-dimensional image provides for enhanced visualization, measurement and analysis of features and characteristics contained within the source image. The gray-scale density may be black-and-white gray-density or RGB color-density or other digital color mapping protocols reduced or converted, for example, to 8-bit 256 gray or color scale. The two-dimensional source image may be a sample of handwriting. A method for enhanced two-dimensional analysis using the digitized bit-map of the source image is also provided.
