&lt;h3 id=&#34;论文介绍&#34;&gt;论文介绍&lt;/h3&gt;
&lt;p&gt;In this paper, we tackle the task of blurry video super-resolution (BVSR), aiming to generate high-resolution (HR) videos from low-resolution (LR) and blurry inputs. Current BVSR methods often fail to restore sharp details at high resolutions, resulting in noticeable artifacts and jitter due to insufficient motion information for deconvolution and the lack of high-frequency details in LR frames. To address these challenges, we introduce event signals into BVSR and propose a novel event-enhanced network, Ev-DeblurVSR. To effectively fuse information from frames and events for feature deblurring, we introduce a reciprocal feature deblurring module that leverages motion information from intra-frame events to deblur frame features while reciprocally using global scene context from the frames to enhance event features. Furthermore, to enhance temporal consistency, we propose a hybrid deformable alignment module that fully exploits the complementary motion information from inter-frame events and optical flow to improve motion estimation in the deformable alignment process. Extensive evaluations demonstrate that Ev-DeblurVSR establishes a new state-of-the-art performance on both synthetic and real-world datasets. Notably, on real data, our method is 2.59 dB more accurate and 7.28× faster than the recent best BVSR baseline FMA-Net.&lt;/p&gt;

&lt;p&gt;本文提出Spiking Point Transformer（SPT），首个基于Transformer的脉冲神经网络框架，用于三维点云分类。SPT设计队列驱动采样直接编码，在降低计算成本的同时保留关键支撑点；并引入混合动力学积分发放神经元（HD-IF），模拟选择性神经元激活，减少对特定人工神经元的过度依赖。在多个真实与合成点云基准上取得领先结果，理论能耗较ANN对应模型降低至少6.4倍。&lt;/p&gt;
