From the Superderivative to a Relative-Gradient Edge Operator

Alejandro Garnung Menéndez

First-derivative edge detectors such as Sobel, Prewitt, Roberts and Scharr measure absolute grey-level differences. We revisit the log-gradient magnitude, a relative-gradient edge…

Soliton resolution conjecture for the Benjamin-Ono equation in the sharp well-posedness space

Hong-Yu Pan, Shou-Fu Tian

We prove the soliton resolution conjecture for the Benjamin-Ono equation in the sharp well-posedness space $H^{s} (R)$ for $s > - \frac{1}{2}$ . This extends soliton resol…
