Paper Abstract

In this paper we propose an effective approach for creating nice-looking photo images of scenes having high dynamic range using a set of photos captured with exposure bracketing. Usually details of dark parts of the scene are preserved in over-exposed shot, and details of brightly illuminated parts are visible in under-exposed photos. A proposed method allows preservation of those details by first constructing gradient field, mapping it with special function and then integrating it to restore lightness values using Poisson equation. Resulting image can be printed or displayed on conventional displays.
