PNTM-CNN: an approach for saddle-point extraction integrating positive–negative terrain method and multiscale fusion CNN model

Saddle-point extraction is essential for accurately identifying topographic features and landforms and conducting geomorphological mapping. However, the widely used positive–negative terrain method (PNTM) is often plagued by a substantial number of false saddle points, a prevalent issue in many extr...
