A Short Note on Weak Estimation of Sharp Function
Mohd. Sarfaraz & M. K. Ahmad · Journal of Advances in Mathematics and Computer Science · 2015
In paper [1] Ahmad et al. investigated the use of sharp function, known from functional analysis, in image processing. The sharp function gives a measure of variations of a function and can be used as an edge detector [2]. We extend the classical notion of sharp function to prove...
