Area of Science:

  • Image Processing
  • Computer Vision
  • Signal Analysis

Background:

  • Edge detection is crucial for image analysis.
  • Existing methods struggle with directional and multiscale edge identification and noise sensitivity.

Purpose of the Study:

  • To develop a robust method for directional and multiscale edge detection.
  • To improve edge map accuracy and noise resistance in image processing.

Main Methods:

  • Utilized orthogonal and linear-phase M-band wavelet transform for image decomposition.
  • Developed decomposition filters to generate zero-crossings at edges across different scales and directions.
  • Applied a zero-crossing detector and Teager's energy operator for enhanced edge map generation.
