Detail Highlighting using a Shadow Edge Histogram
Anastasios Gkaravelis, Georgios Theodoros Papaioannou · Eurographics · 2017
In this paper we propose a simple and effective technique for setting up a configuration of directional light sources to accentuate the prominent geometric features of complex objects by increasing the local shadow contrast near them. Practical applications of such a task are encountered among others in professional photography, and cinematography. The method itself, which is based on a voting mechanism, quickly produces consistent and view-independent results, with minimal user intervention.
