Using power spectral analysis, centennial and millennial-scale cycles of Paleo-monsoon were extracted. In the cycles, 71 a is the basic cycle of East Asian Monsoon.
Firstly, texture and shape features are extracted at the pixel level, and spectral features are extracted at the object level based on multi-scale image segmentation maps.
