Co-registration

Detection and matching of features from satellite images.


Introduction

This block performs the spatial alignment of 2 images based on the calculation of translation, rotation and scale variation.

Technical Information

Algorithm description

This block calculates the translation, rotation and scale variation between two images and ensures that the images become spatially aligned and any feature in the images overlaps. This block is based on the DFT image registration python package.

This block currently accepts only two images, where the second image is geometrically aligned with the first image.

Output files

This block generates outputs in GeoTIFF format.

Geographic coverage

The geographic coverage is global.

How it works

This block has no configurable JSON parameters.

Disclaimer

This algorithm has the following limitations:

  • The input images must have the same size and shape
  • The input images must be in GeoTIFF format.
  • It is recommended to select an AOI greater than 1 square kilometer and to use the geometric filter contains.
