Hyperspectral Fourier-Mellin algorithm (HYFM) on GPU

Requirements

• NVIDIA GPU with compute capability 6.1.
• Ubuntu 14.04 or later

Dependencies

• NVIDIA CUDA Toolkit
• Install: sudo apt-get install libmatio-dev

Usage

Run ./HYFMGPU with the following parameters:

./HYFMGPU <reference_image.mat> <target_image.mat>

Outputs:

• Textual result in console: scale, angle of rotation, and shifts over x and y axis.
• An original band of reference and target images in PGM format.
• A registered band image in PGM format.
• Registered hyperspectral image in MAT format.

Additional program

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

Use:

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

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

Examples

Using Santa Barbara Line images:

./HYFMGPU SantaBarbaraLine2013.mat SantaBarbaraLine2014.mat

Using Pavia University image:

1. ./rot_scal PaviaUniversity.mat 2.0 90
2. ./HYFMGPU PaviaUniversity.mat ./rot_scal_out.mat
