Abstract: Systems, methods, and non-transitory media are provided for frequency domain edge enhancement of multi-exposure high dynamic range (HDR) images. An example method can include determining an alignment between an HDR frame and a frame having an exposure time above a threshold; adjusting the frame based on the alignment; determining a gradient estimation map representing differences between image blocks in the HDR frame and image blocks in the frame; and generating, based on the gradient estimation map, a merged frame that includes a combination of at least some image data from the HDR frame and at least some image data from the frame.
