Abstract
The Goal of this study is development of automatic extraction algorithm for craters, ridges, and grabens on DTM (Digital Terrain Model). Edge detection of topographic features is one of the most important parts of the extraction algorithm. The followings are candidates of methods for edges detections: (1) FFT (Fast Fourier Transform), (2) Hierarchical FFT, (3) Haar - Wavelet Transform. Their results will be reported.
