Abstract
Compares the performance of topographic analysis and binary
analysis for recognition of digits in hydrographic maps. The performance
of each method was measured by the correct classification rate of the
final symbol recognition step when processing a complete hydrographic
map of size 0.45×0.6 m2 with about 35000 digits. The
experimental results indicated that binary analysis had a better
performance than topographic analysis. Overall, the performance of the
binary analysis was acceptable
