Preformer: Predictive Transformer with Multi-Scale Segment-wise Correlations for Long-Term Time Series Forecasting

1 code implementation23 Feb 2022 Dazhao Du, Bing Su, Zhewei Wei

In this way, if a key segment has a high correlation score with the query segment, its successive segment contributes more to the prediction of the query segment.

Do we really need temporal convolutions in action segmentation?

1 code implementation26 May 2022 Dazhao Du, Bing Su, Yu Li, Zhongang Qi, Lingyu Si, Ying Shan

Most state-of-the-art methods focus on designing temporal convolution-based models, but the inflexibility of temporal convolutions and the difficulties in modeling long-term temporal dependencies restrict the potential of these models.

UIEDP:Underwater Image Enhancement with Diffusion Prior

no code implementations11 Dec 2023 Dazhao Du, Enhan Li, Lingyu Si, Fanjiang Xu, Jianwei Niu, Fuchun Sun

To address this issue, we propose UIE with Diffusion Prior (UIEDP), a novel framework treating UIE as a posterior distribution sampling process of clear images conditioned on degraded underwater inputs.

End-To-End Underwater Video Enhancement: Dataset and Model

1 code implementation18 Mar 2024 Dazhao Du, Enhan Li, Lingyu Si, Fanjiang Xu, Jianwei Niu

To fill this gap, we construct the Synthetic Underwater Video Enhancement (SUVE) dataset, comprising 840 diverse underwater-style videos paired with ground-truth reference videos.
