Edge Detection using Non-Radial Discrete Hilbert Transform

Image Edge Detection using Non-Radial Discrete Hilbert Transform, Otsu binarization and morphological skeletonization

This paper presents an algorithm to detect edges of non-localized or unclear

objects in 2D images, utilizing a methodology composed of three stages: the application

of the Hilbert transform, Otsu’s binarization method, and Lantu´ejoul’s

skeletonization. To computationally validate the proposal, an example is presented

in which this methodology is developed, and an analysis and comparison

are made with other similar existing methods.
