Real-time ghost free HDR video stream generation using weight adaptation based method

Abstract : Temporal exposure bracketing is a simple and low cost technique to generate a high dynamic range (HDR) images. This technique is widely used to recover the whole dynamic range of a scene by selecting the adequate number of low dynamic range (LDR) images to be fused. Temporal exposure bracketing technique is introduced to be used for static scenes and it cannot be applied directly for dynamic scenes since camera or object motion in bracketed exposures creates ghosts in the resulting HDR image. In this paper we propose a HDR algorithm modification to remove ghost artifact and we present a real-time implementation of this method on a smart camera (HDR video stream 1280 x 1024 at 60fps). We present experimental results to show the ghost removing efficiency of our implemented method.
