Experimental results related to the paper Fourier-Mellin registration of two hyperspectral images by Álvaro Ordóñez, Francisco Argüello, and Dora B., that it is under revision.

Hyperspectral images contain a great amount of information which can be used to more robustly register such images. In this paper, we present a phase correlation method to register two hyperspectral images that takes into account their multiband structure. The proposed method is based on principal component analysis, multilayerfractional Fourier transform, combination of log-polar maps, and peak processing. The combination of maps is intended to highlight some peaks in the log-polar map using information from different bands. The method is robust and has been successfully tested for any rotation angle with commonly used hyperspectral scenes in remote sensing for scales up to 7.5× and with pairs of hyperspectral images taken on different dates by the AVIRIS sensor for scales up to 6.0×.

Compiled program to register two hyperspectral images.

• HYFM algorithm: hyfm-reg.zip (how to use in the README file)

• Commonly used hyperspectral datasets from Universidad del Pais Vasco: www.ehu.es
• Pairs of datasets taken on different dates from AVIRIS NASA: ACTUALIZAR ISTO

Example of registration process: (a) original or reference image, (b) target image (central region of the original image scaled by 5.5× and rotated 45 degrees), and © result of the registration process showing the superposition of the reference and target image correctly registered.
