The Research of Rotating and Zooming Fixity in Recognition of Mark Map Symbols
Xiaoying He · Geomatics & Spatial Information Technology · 2007
Two methods are realized to reach the fixity results when rotating and zooming symbols in symbols recognition.The former is to get the characters which do not change when being rotated or zoomed,then these characters are put into network to recognize symbols.The later is to build a special compound net which can recognize symbols without focusing on the changing of mark.
