Abstract

The article deals with the possibilities of establishing the sequence of handwritten and printed entries in cases with no direct intersection of the two. You can follow the research and development of a method based on direct optical evaluation using a digital microscope with maximum magnification of up to 800x and 2500x, and a method of indirect optical evaluation according to the distribution of toner particles on a sheet of paper using a simple micro zoom camera.
