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 Lantuéjoul’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.
