所以,本文的动机是结合convolution的局部建模能力和self-attention的全局建模能力,联合捕捉视频的长-短期时间信息。 1.2 解决方案 如上图所示,本文提出了一种Multi-Scale Temporal ConvTransformer(MS-TCT)网络结构,它由四部分组成:Visual Encoder 、Temporal Encoder、Temporal Scale Mixer和Classification Module。该模型主要...
we propose a novel network named Multi-scale Attention Net (MA-Net) by introducing self-attention mechanism into our method to adaptively integrate local features with their global dependencies. The MA-Net can capture rich contextual dependencies based on the attention mechanism. We design two blocks...
1、Multi-scale Large Kernel Attention (MLKA) MLKA首先使用 Point-wise conv 改变通道数,然后将特征 split 成三组,每个组都使用 VAN 里提出的大核卷积来处理(即depth-wise conv,dilated conv,和 point-wise conv 的组合)。三组分别使用不同尺寸的大核卷积(7×7、21×21、35×35),膨胀率分别设置为(2,3...

Multi-Stage Multi-Scale Framework - 作者们一步采用了多阶段框架,因为与扩大模型宽度或高度相比,发现它更高效。 作者们认为完整的分辨率处理是比multi-patch的分层结构更好的方法,因为后者可能会在patch之间引入边界效应。 为了实现更强的监督,作者们采用了多尺度input-output的方法[Rethinking coarse-to-fine approach...
