Abstract
In this paper we present a new concept of selecting a subset of significant images from a large sequence of multi exposure bracketing photographs, used for HDR imaging. Presented algorithm picks up several frames from a sequence taken with increasing exposure and use them to generate high dynamic range image. The choice allows us to obtain the photos with important data and to discard the images with redundant or deformed visual information, like overburned or dark areas. We have tested the presented technique by selecting \(n=7\) significant frames from the bracketing sequence of 49 elements. The chosen photos have been used to compose an HDR image which contains a maximum insight of the scene with a minimal presence of luminous deformations.
