CrImage::Transform::EdgeOperator

Inherits Enum / Comparable / Value / Object

Edge detection operators for finding boundaries in images.

Available operators:

  • Sobel : Most common, good balance of accuracy and noise resistance
  • Prewitt : Similar to Sobel with equal weighting
  • Roberts : Fast 2x2 operator, more sensitive to noise
  • Scharr : Improved Sobel with better rotational symmetry

Constants

Sobel = 0
Prewitt = 1
Roberts = 2
Scharr = 3
