This study introduces a novel method using Determinism from Recurrence Quantification Analysis to improve noise removal in optical imaging. It enhances signal processing parameter selection, outperforming traditional signal-to-noise ratio methods.

Area of Science:

  • Optical imaging
  • Signal processing
  • Biomedical engineering

Background:

  • Effective noise removal is crucial for accurate analysis of optical imaging data.
  • Traditional methods for selecting signal processing parameters, like signal-to-noise ratio, can be suboptimal for complex biological signals.

Purpose of the Study:

  • To introduce a novel method for selecting signal processing parameters in optical imaging.
  • To improve noise quantification and removal in optical signals with diverse tissue pathologies.
  • To demonstrate the limitations of using signal-to-noise ratio alone for parameter selection.

Main Methods:

  • Utilizing the change in Determinism, a Recurrence Quantification Analysis measure.
  • Applying the change in residual noise Determinism for parameter selection.
