HDR-GAN: HDR Image Reconstruction From Multi-Exposed LDR Images With Large Motions [PDF]
IEEE Transactions on Image Processing, 2021 Synthesizing high dynamic range (HDR) images from multiple low-dynamic range (LDR) exposures in dynamic scenes is challenging. There are two major problems caused by the large motions of foreground objects. One is the severe misalignment among the LDR images. The other is the missing content due to the over-/under-saturated regions caused by the moving

HDR Image Reconstruction Using Segmented Image Learning [PDF]
IEEE Access, 2021 Converting a low dynamic range (LDR) image into a high dynamic range (HDR) image produces an image that closely depicts the real world without requiring expensive devices. Recent deep learning developments can produce highly realistic and sophisticated HDR images. This paper proposes a deep learning method to segment the bright and dark regions from an
