# 초분광 이미징 분석 기술
높은 공간 및 스펙트럼 정보를 포함하는 초분광 큐브는 수십 ~ 수백 메가바이트의 대용량으로, 대기 및 기하학적인 왜곡 등 물리적인 요인뿐만 아니라, 데이터의 혼합된 픽셀, 인접 대역에서의 높은 상관관계로 인한 높은 데이터 중복성, 초분광 시그니처의 가변성, 그리고 차원의 저주(curse of the dimensionalit…

@afalty and I just spoke about their hyperspectral image analysis routine and database. They have plans to make the database and analysis routine open source and want to see it applied in Open Specy. …

Hello
the paper with DOI contains a review of several methods to express the distance between two spectra.
Its most significant contribution is IMHO to normalize an energy spectrum by its integr…

I was really excited to see this repo get published!
We have a current goal to implement hyperspectral image analysis on Open Specy https://github.com/wincowgerDEV/OpenSpecy/issues/105
I am won…

MNF transforms can be ordered in either increasing or decreasing SNR. The former was used by the original reference [1] although ordering by decreasing SNR (==increased noise) is the most used in prac…
