This study discusses general two-dimensional zero-crossing discontinuity detectors. An optimal detector maximizing signal-to-noise ratio was derived and tested on real images.

Area of Science:

  • Computer Vision
  • Image Processing
  • Signal Processing

Background:

  • Zero-crossing-based discontinuity detection is crucial for image analysis.
  • Existing methods like Marr-Hildreth and Difference of Gaussians are special cases of a broader class.

Purpose of the Study:

  • To discuss general two-dimensional zero-crossing-based discontinuity detectors.
  • To provide mathematical justification for this class of detectors.
  • To derive an optimal detector that maximizes signal-to-noise ratio.

Main Methods:

  • Discussion of general zero-crossing-based discontinuity detectors.
  • Mathematical derivation and justification of the detector class.
  • Optimization of the detector to maximize signal-to-noise ratio.
