Abstract: A method of enhancing a source image for analysis. The method comprises the steps of digitizing the source image to obtain pixel data comprising location data and density data, generating a three-dimensional model of the pixel data with the location data represented in first and second axes and the density data represented in a third axis, and analyzing the three-dimensional model to determine features of the source image.

Abstract: A method for electronic analysis of handwriting samples. A digital bit-map of handwriting samples created, using a digital camera or electronic scanner. The bit-map is then marked at selected points using a cursor to obtain measurements, such as the slant angles of strokes and height measurements of major areas in the writing. The measurements are tabulated and may be used to authenticate the handwriting sample. Also, the tabulated results may be compared with predetermined standard profiles for determining certain characteristics relating to the person who produced the handwriting sample. The invention also provides a method for determining the pressure and angle of the writing instrument, by creating a three-dimensional representation of portions of the writing sample for measurement and analysis.
