Underwater image restoration and enhancement are essential for correcting color distortion and restoring details in images, which are crucial for various underwater visual tasks. Current deep learning methods face challenges due to the lack of high-quality paired datasets, as pristine reference labels are hard to obtain in underwater environments. This paper proposes a novel approach that utilizes in-air natural images as reference targets, translating them into underwater-degraded versions to create synthetic datasets that provide authentic supervision for model training.

Sparse-view synthesis presents challenges in accurately recovering geometry and appearance from limited observations. Recent advancements in 3D Gaussian Splatting (3DGS) have improved real-time rendering quality, yet existing methods often depend on Structure-from-Motion (SfM) for camera pose estimation, which is ineffective in sparse-view scenarios. The proposed Segmentation-Driven Initialization for Gaussian Splatting (SDI-GS) addresses these inefficiencies by utilizing region-based segmentation to focus on structurally significant areas, allowing for effective downsampling of dense point cl…

Saliency maps are essential for providing visual explanations in deep learning, yet there remains a significant lack of consensus regarding their purpose and alignment with user queries. This uncertainty complicates the evaluation and practical application of these explanation methods. To address this, a new taxonomy called Reference-Frame × Granularity (RFxG) is proposed, categorizing saliency explanations based on two axes: Reference-Frame and Granularity. This framework highlights limitations in existing evaluation metrics, emphasizing the need for a more comprehensive approach.

Meta-SimGNN is a novel WiFi localization system that combines graph neural networks with meta-learning to enhance localization generalization and robustness. It addresses the limitations of existing deep learning-based localization methods, which primarily focus on environmental variations while neglecting the impact of device configuration changes. By introducing a fine-grained channel state information (CSI) graph construction scheme, Meta-SimGNN adapts to variations in the number of access points (APs) and improves usability in diverse scenarios.

The Cross-Modal Compositional Self-Distillation (CCSD) framework has been proposed to enhance brain tumor segmentation from multi-modal MRI scans. This method addresses the challenge of missing modalities in clinical settings, which can hinder the performance of deep learning models. By utilizing a shared-specific encoder-decoder architecture and two self-distillation strategies, CCSD aims to improve the robustness and accuracy of segmentation, ultimately aiding in clinical diagnosis and treatment planning.

The paper presents a Doppler Invariant Convolutional Neural Network (CNN) designed for automatic signal classification in radio spectrum monitoring. It addresses the limitations of existing deep learning models that rely on Doppler augmentation, which can hinder training efficiency and interpretability. The proposed architecture utilizes complex-valued layers and adaptive polyphase sampling to achieve frequency bin shift invariance, demonstrating consistent classification accuracy with and without random Doppler shifts using a synthetic dataset.
