Vergrösserung von digitalen Farbbildern zur Kantenabbildung

摘要

The method involves producing an edge map with a number of boundaries by analysing the digital image to pick locations in neighbourhoods where levels change significantly and then connecting the picked locations to form edges. The edge map is then projected onto the digital image, and one or more additional pixels are generate in locations among the original pixels by manipulating the levels of one or more original pixels that do not have among them any boundaries set by the edge map. E.g. the total number of additional pixels is related to the number of original pixels and the magnification.
