This disclosure provides systems, methods, and devices that perform object-aware guided exposure fusion for tone mapping high dynamic range (HDR) images to lower dynamic range images. In one aspect, a method is provided that includes receiving a first image frame and generating a plurality of second image frames, each corresponding to an exposure value that differs from the first image frame. The method further includes determining segmentation maps of objects within the first image frame and computing exposure scores for image regions defined by the segmentation maps in each second image frame, such as based on deviation of intensity levels from a reference intensity level. Weights are determined based on these scores, and an output image is generated by combining the second image frames using guided multi-scale image fusion. Fusion may incorporate pyramid decomposition techniques and guided filtering. Other aspects are provided.
