Hyperspectral Fourier-Mellin algorithm (HYFM)

How to register

Run ./HYFM-reg with the following parameters:

./HYFM-reg <reference_image.raw> <target_image.raw> <image_width> <image_height> <number_bands>

Outputs:

• Textual result in console: scale, angle of rotation, and shifts over x and y axis.
• Original band 0 of reference and target images in PGM format.
• Registered band 0 image in PGM format.
• Registered hyperspectral image in RAW format.

Additional program

rot_scal allows to generate new target images with specific a scale and angle of rotation for testing the performance of the method.

Use:

./rot_scal <image.raw> <scale> <angle>

The output image is saved in the same directory with the name rot_scal_out.raw.

Examples

Using Santa Barbara Line images:

./HYFM-reg barbara_line_2013.raw barbara_line_2014.raw 769 1024 224

Using Pavia University image:

1. ./rot_scal PaviaU.raw 2.0 90
2. ./HYFM-reg PaviaU.raw ./rot_scal_out.raw 340 610 103
