Use of an Occlusion Mask for Veiling Glare Removal in HDR Images

Use of an Occlusion Mask for Veiling Glare Removal in HDR Images

Optical systems in digital cameras present a limit during the acquisition of standard and High Dynamic Range Images (HDRI) due to the presence of veiling glare, an artifact caused by an unwanted spread of the source of light. In this paper, we analyze the state-of-the-art of veiling glare removal in...
