Multi-exposure image fusion for dynamic scenes without ghost effect

Abstract

Fusion of multi-exposure images for dynamic scenes often show ghost effect. This is mainly due to motion blur present in the image sequences or due to presence of totally new object. Detection and removal of such ghost effect plays an important role for automatically generating HDR images of dynamic scenes. In this paper, we present a simple, yet effective method for multi-exposure image fusion for dynamic scenes with new objects without ghost effect. The proposed method is carried out in four steps, viz.: weight map generation, new object detection, modification of weight maps and finally exposure fusion using modified weight maps. The experimental result show that our method produce HDR images without noticeable ghost effect.
