CVIT Observer Models


This module provides an API for common observer model calculations.

  • Designed to process the output of image simulation data from the CVIT simulation pipeline.
  • Provides detectability indices for a number of observer models under the signal-known-exactly (SKE) paradigm.
  • Calculations can be done using a number of source data types:
    • Fourier-domain image quality metrics (MTF and NPS)
    • Image ensembles with various degrees of a priori knowledge of the noise and signal properties (e.g., estimated from samples or assumed/input)
  • Calculations can use a number of observer models:
    • Non-prewhitening matched filter
    • Prewhitened matched filter
    • Channelized Hotelling observer (coming soon)
