“…DL-based HDR imaging methods often achieve stateof-the-art (SoTA) performances on various benchmark datasets. Deep neural network (DNN) models have been developed based on diverse architectures, ranging from convolutional neural networks (CNNs) [9], [10], [16] to generative adversarial networks ‚ L. Wang (GANs) [17], [18], [19]. In general, SoTA-DNN-based methods differ in terms of five major aspects: network design that considers the number and domain of input LDR images [9], [10], [14], purpose of HDR imaging in multitask learning [20], [21], different sensors being used to obtain deep HDR imaging [22], [23], [24], novel learning strategies [17], [25], [26], and practical applications [27], [28], [29].…”
