Abstract:
This paper introduces a map reading system to make fully automatic
interpretation of the municipal maps of Taiwan. Here we use a mixed
processing algorithm ( bottom-up and top-down approaches) to interpret
the maps. The bottom-up approach includes the color segregation,
symbol recognition, road extraction, and related characters string
extraction. The top-down approach guided by a priori knowledge
resolves the inconsistency between the extracted objects. In the
experiments, we illustrate that our system can interpret the municipal
map effectively.
