HTRI: High Time Range Imaging

Résumé

In the same vein as HDRI, we have developed a new approach to image fusion from a series of photographs of the same scene taken at different timestamps. When compared with HDRI, exposure bracketing at a single timestamp is replaced by timestamp variation disregarding exposure times. This technique is called HTRI (High Time Range Imaging), it aims at capturing ephemeral events occurring over a long time period during which a sequence of images is shot. For each pixel location, the most salient colors are privileged in the series of photographs, based on the existing admitted definitions of visual attention. Then, salient moving objects are automatically detected, without introducing a significant amount of noise, and despite the large illumination changes that may occur in the acquisition conditions from one frame to the next. Experiments evaluate the impact of the method parameters, and show different possibilities offered by the method.
