High Dynamic Range Imaging via Visual Attention Modules
This addresses the limitation of existing HDR methods that neglect informative image parts, offering an incremental improvement for photography and imaging applications.
The paper tackled the problem of reconstructing lost luminosity in High Dynamic Range (HDR) imaging from Low Dynamic Range images by introducing a model that incorporates visual attention modules to focus on informative image areas, resulting in outperforming most State-Of-The-Art algorithms.
Thanks to High Dynamic Range (HDR) imaging methods, the scope of photography has seen profound changes recently. To be more specific, such methods try to reconstruct the lost luminosity of the real world caused by the limitation of regular cameras from the Low Dynamic Range (LDR) images. Additionally, although the State-Of-The-Art methods in this topic perform well, they mainly concentrate on combining different exposures and have less attention to extracting the informative parts of the images. Thus, this paper aims to introduce a new model capable of incorporating information from the most visible areas of each image extracted by a visual attention module (VAM), which is a result of a segmentation strategy. In particular, the model, based on a deep learning architecture, utilizes the extracted areas to produce the final HDR image. The results demonstrate that our method outperformed most of the State-Of-The-Art algorithms.
