Description and Objectives

• To provide fast and accurate image registration for:
  • Spatial and radiometric calibration of multi-temporal measurements
  • Accurate change detection
  • Extrapolation of data throughout several scales for multi-scale phenomena
• To provide methods applicable for the ground or onboard with adaptive levels of processing speed and accuracy, including a choice of full images or chips registration

On the Ground or On Board Automatic Image Registration

Technical Approach

• Leverage previous algorithms development with:
  • Feature extraction based on wavelet decomposition
  • Feature matching based on a multi-resolution optimization search of a rigid transformation
  • An optional resampling option
• Utilize USGS/Global Land Survey (GLS 2000) orthorectified maps as ground truth or reference for the registration algorithms
• Create a chip database extracted from GLS2000
• Test algorithms using EO ALI data

Main Innovation(s)

• Utilization of the newly developed GLS database
• Automatic extraction of chips in input scenes based on chip database
• Automatic registration with subpixel accuracy in seconds

Infusion Potential

• Applicable to any Earth Science image data
