Fuzzy Edge Detection on Hyperspectral Images Using Upper and Lower Operators.

There exists a continuous research effort aiming to port methods for grayscale image processing to more complex imagery data. Color images were an initial target for such effort, but new technologies have lead to many other types of images. In this work we focus on hyperspectral images. Specifically, we analyze how to adapt the Upper-Lower Edge Detector (ULED) to hyperspectral images; our proposal consist of fusioning band-wise information using OWA operators.
