Dual Frequency Transformer for Efficient SDR-to-HDR Translation

The SDR-to-HDR translation technique can convert the abundant standard-dynamic-range(SDR)media resources to high-dynamic-range(HDR)ones,which can represent high-contrast scenes,providing more realistic visual experiences.While recent vision Transformers have achieved promising performance in many low-level vision tasks,there are few works attempting to leverage Trans-formers for SDR-to-HDR translation.In this paper,we are among the first to investigate the performance of Transformers for SDR-to-HDR translation.We find that directly using the self-attention mechanism may involve artifacts in the results due to the inappropriate way to model long-range dependencies between the low-frequency and high-frequency components.Taking this into account,we ad-vance the self-attention mechanism and present a dual frequency attention(DFA),which leverages the self-attention mechanism to sep-arately encode the low-frequency structural information and high-frequency detail information.Based on the proposed DFA,we further design a multi-scale feature fusion network,named dual frequency Transformer(DFT),for efficient SDR-to-HDR translation.Extens-ive experiments on the HDRTV1K dataset demonstrate that our DFT can achieve better quantitative and qualitative performance than the recent state-of-the-art methods.The code of our DFT is made publicly available at https://github.com/CS-GangXu/DFT.
