Deconvolution01:20

Deconvolution

162
Deconvolution, also known as inverse filtering, is the process of extracting the impulse response from known input and output signals. This technique is vital in scenarios where the system's characteristics are unknown, and they must be inferred from the observable signals.
Deconvolution involves several mathematical techniques to derive the impulse response. One common approach is polynomial division. In this method, the input and output sequences are treated as coefficients of...

Super-resolution Fluorescence Microscopy

7.0K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Area of Science:

  • Optics and Photonics
  • Digital Image Processing
  • Computational Imaging

Background:

  • Current methods for extending camera depth of field (DoF) often involve complex joint optimization of optical elements and digital processing with infinite deconvolution or neural networks.
  • These techniques aim to improve imaging at greater distances or relax manufacturing tolerances for sensor positioning.

Purpose of the Study:

  • To investigate depth of field (DoF) extension using embedded digital processing with a single finite convolution.
  • To compare different finite impulse response (FIR) filter approaches, including learned and Wiener filter paradigms.

Main Methods:

  • Developed an optical model for codesigned systems focused on DoF extension.
  • Employed a Wiener filter paradigm to compute FIR filter coefficients, incorporating scene power spectral density (either learned or modeled).
  • Compared various FIR filter designs and proposed a method for pre-optimizing filter sizes.

Main Results:

  • Demonstrated the feasibility of DoF extension with single finite convolutions.
  • Showcased that learned FIR filters offer adaptability to datasets, while Wiener-based filters provide comparable robustness.
  • Presented a method for dimensioning FIR filter sizes before joint optimization.

Conclusions:

  • Embedded processing with FIR filters is an effective strategy for depth of field extension.
  • Both learned and Wiener filter approaches are viable, offering different advantages in terms of adaptability and robustness.
  • The proposed dimensioning method aids in optimizing FIR filter performance for DoF extension systems.
