Technology Overview

DAHi represents a significant leap in hyperspectral image analysis by employing Shannon's entropy to simplify the data from a three-dimensional hyperspectral data cube into a two-dimensional map, effectively retaining all chemical information. This method calculates an information content (IC) value for each spectrum, allowing for a more accurate inference of chemical variations.


Key Advantages

  • Reduces data complexity without losing chemical information
  • Employs a single characteristic number to process data, enhancing efficiency
  • Overcomes limitations of traditional methods like PCA and MCR
  • Enables more accurate identification of different material compositions

Problems Addressed

  • Complexity and volume of data in hyperspectral images
  • Limitations of traditional analysis methods in handling large datasets
  • Difficulty in accurately identifying material compositions from hyperspectral data

Market Applications

  • Enhanced analysis in instruments like EDS, TOF-SIMS, and RAMAN
  • Material distribution analysis at micro to nanoscale resolutions
  • Potential applications in fields requiring detailed chemical imaging
