CVIT Observer Models

Description

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)
