Reflectance Prediction-based Knowledge Distillation for Robust 3D Object Detection in Compressed Point Clouds

This paper proposes a Reflectance Prediction-based Knowledge Distillation (RPKD) framework that enhances 3D object detection robustness in low-bitrate compressed point clouds by discarding reflectance during transmission, reconstructing it via a geometry-based prediction module, and utilizing a cross-source distillation strategy to transfer knowledge from raw to compressed data.

Is Exchangeability better than I.I.D to handle Data Distribution Shifts while Pooling Data for Data-scarce Medical image segmentation?

This paper addresses the "Data Addition Dilemma" in medical image segmentation by proposing an exchangeability-based framework that controls foreground-background feature discrepancies across deep network layers, achieving state-of-the-art performance on five datasets including a novel curated ultrasound collection.

Detection and Measurement of Hailstones with Multimodal Large Language Models

This study demonstrates that pre-trained multimodal large language models, particularly when enhanced with two-stage prompting strategies that leverage reference objects, can effectively detect and measure hailstone diameters from crowdsourced social media images with an average error of 1.12cm, offering a promising complement to traditional hail sensors for rapid severe weather assessment.

Deforming Videos to Masks: Flow Matching for Referring Video Segmentation

The paper proposes FlowRVS, a novel one-stage generative framework that reformulates Referring Video Object Segmentation as a language-guided continuous flow deformation problem, leveraging pretrained text-to-video models to achieve state-of-the-art performance by directly mapping video representations to target masks while overcoming the limitations of traditional cascaded approaches.
