Ghost-like artifact caused by ill-exposed and motion areas is one of the most challenging problems in high dynamic range (HDR) image reconstruction. When small, previous methods based on optical flow or patch-match can suppress ghost-like artifacts first aligning input images before merging them. However, they are not robust enough still produce for scenes where large foreground motions exist. To this end, we propose a deep network with an attention module motion-emphasized loss function to...
