Leveraging Deep Convolutional Neural Network for Point Symbol Recognition in Scanned Topographic Maps

Leveraging Deep Convolutional Neural Network for Point Symbol Recognition in Scanned Topographic Maps

Point symbols on a scanned topographic map (STM) provide crucial geographic information. However, point symbol recognition entails high complexity and uncertainty owing to the stickiness of map elements and singularity of symbol structures. Therefore, extracting point symbols from STMs is challengin...
