Using Eigenvectors of a Vector Field for Deriving a Second Directional Derivative Operator for Color Images |
Abstract | ||
|---|---|---|
Edge detection in color images could be seen as detecting changes in a vector field.This paper presents a survey on existing methods and their difficulties. A second directional derivative approach is proposed, using eigenvalues and eigenvectors of a vector field for deriving a color edge detector and avoiding some ambiguities in the gradient direction estimation. Qualitative studies are presented by applying and comparing the different technics on a real image. |
