We developed stabilized inverse diffusion equations (SIDEs) for image processing. These novel equations effectively reduce noise while enhancing image edges and aiding segmentation.

Area of Science:

  • Applied Mathematics
  • Image Processing
  • Differential Equations

Background:

  • Image processing often requires noise reduction and edge enhancement.
  • Existing methods like the Perona-Malik equation have limitations in certain scenarios.

Purpose of the Study:

  • Introduce a new family of equations, stabilized inverse diffusion equations (SIDEs).
  • Demonstrate the effectiveness of SIDEs in image processing tasks, including noise suppression, edge sharpening, and segmentation.

Main Methods:

  • Developed first-order multidimensional ordinary differential equations (ODEs) with discontinuous right-hand sides.
  • Defined SIDEs as inverse diffusion with stabilization at local extrema.
  • Proved existence, uniqueness, and stability of solutions for SIDEs.
