Hyperspectral Image Analysis Using Hilbert-Huang Transform [PDF]

open access: yes, 2013
高光譜影像具有豐富且細緻的地物光譜資訊,有助於地物的判釋,並且提升影像分類之精度。然而受限於高光譜影像之高維度資料統計特性,在訓練樣本數不足的情況下,傳統以統計為基礎的影像分類方法並無法直接適用,這樣的問題一般稱為「維度的詛咒」。若在高光譜影像分類前,先透過適當的特徵萃取方法縮減高光譜影像的資料維度,將可有效解決「維度的詛咒」之問題。本研究應用Hilbert-Huang transform(HHT)方法於高光譜影像之光譜曲線分析與特徵萃取,以獲得有利於高光譜影像分類之光譜特徵 ...
