In recent years, remarkable progress has been witnessed with deep learning techniques. Despite the promising performance achieved on synthetic data, compelling research challenges remain to be addressed in the wild. These include: (i) degradation models for low-quality images in the real world are complicated and unknown, (ii) paired low-quality and high-quality data are difficult to acquire in the real world, and a large quantity of real data are provided in an unpaired form, (iii) it is challenging to incorporate cross-modal information provided by advanced imaging techniques (e.g. RGB-D camera) for image restoration, (iv) real-time inference on edge devices is important for image restoration and enhancement methods, and (v) it is difficult to provide the confidence or performance bounds of a learning-based method on different images/regions. This special issue invites original contributions in datasets, innovative architectures, and training methods for image restoration and enhancement to address these and other challenges.&lt;/p&gt;&lt;p&gt;In this Special Issue, we have received 17 papers, of which 8 papers underwent the peer review process, while the rest were desk-rejected.

In time series action prediction for different scales, existing methods mainly focus on attention mechanisms to enhance modelling capabilities in spatial dimensions. However, this approach strongly depends on the local information of a single input feature and fails to facilitate the flow of information between channels. To address these issues, the authors propose a novel Temporal Channel Reconfiguration Multi-Graph Convolution Network (TRMGCN). In the temporal convolution part, the authors designed a module called Temporal Channel Fusion with Guidance (TCFG) to capture important temporal information within channels at different scales and avoid ignoring cross-spatio-temporal dependencies among joints. In the graph convolution part, the authors propose Top-Down Attention Multi-graph Independent Convolution (TD-MIG), which uses multi-graph independent convolution to learn the topological graph feature for different length time series. Top-down attention is introduced for spatial and channel modulation to facilitate information flow in channels that do not establish topological relationships. Experimental results on the large-scale datasets NTU-RGB + D60 and 120, as well as UAV-Human, demonstrate that TRMGCN exhibits advanced performance and capabilities.

In addition, the authors construct a large-scale, multi-size snowy dataset called Synthetic and Real Snowy Dataset (SRSD), and it is a good and necessary complement and improvement to the existing snowy-related tasks.
