TL;DR: An algorithm based on the facts of the human visual system is presented here whereby it is possible to select automatically (without human intervention) the thresholds for detecting the significant edges as perceived by human beings.

TL;DR: A new Pattern Recognition (P R) based coding method for two tone contour type of graphics is introduced and the relative data compressibility of this method is compared with that of different widely used representative coding methods.
Abstract: A new Pattern Recognition (P R) based coding method for two tone contour type of graphics is introduced in this paper. The basic P R concept used here is the detection of a digital line segment in accordance with the Freeman's definition of digital line. The relative data compressibility of the new method is compared with that of different widely used representative coding methods. The relative performances of all methods are studied both on normal and noisily degraded data. The effect of gradual increase of noise level on data compressibility is studied for all the methods. The extension of the new methods is also proposed.
TL;DR: A new pel modification technique which preserves some topological properties of two-tone image by creating more uniform gray-level blocks than were present in the originals two- Tone image, which enhances the compression efficiency of the block coding for two- tone image.
