This study presents a probabilistic method for object restoration under spatially incoherent illumination. The approach incorporates a positivity constraint using quadratic programming for improved accuracy in noisy conditions.

Area of Science:

  • Optics
  • Image Processing
  • Computational Science

Background:

  • Inverse problems often require regularization for stable solutions.
  • Positivity constraints are crucial in many physical imaging scenarios.

Purpose of the Study:

  • To develop a regularized solution for object restoration with spatially incoherent illumination.
  • To introduce a numerical algorithm based on statistical analysis of noisy data.
  • To effectively incorporate the positivity constraint into the restoration process.

Main Methods:

  • A probabilistic approach was used to formulate a regularized solution.
  • A numerical algorithm was developed utilizing statistical analysis of noisy data.
