📖论文解读

本文作者提出了一个【轻量级、实时】的IVF网络，该网络能够自适应地学习像素权值进行图像融合。并且作者将【目标检测作为下游任务】，【联合优化】网络参数。

🔑关键词

Multispectral image fusion 多光谱图像融合
Lightweight model 轻量级模型
Joint optimization 联合优化
Real-time 实时
Embedded platform 嵌入式平台

💭核心思想

采用【自适应像素加权】（Adaptive Pixel Weighting strategy， APWNet）策略融合图像，并联合【目标检测】下游任务。具体来说，将可见光和红外光图像concat后输入卷积层，提取权值图，然后将其分别与对应的源图逐元素乘和加操作得到融合图像，将融合图像作为yolov5s的输入进行目标检测。（在训练过程中，根据检测结果反向优化网络参数）

🪢网络结构

作者提出的网络结构如下所示。

首先将拼接后的红外和可见光图像送入一系列卷积层和sigmoid层，生成输入图像的权值图。然后对融合图像进行逐元运算和最大最小归一化。最后，将融合后的图像输入检测器，端到端联合训练整个网络。

$I_{ir}$和$I_{vi}$分别代表红外图像和可见光图像，$W_{ir}$和$W_{vi}$代表源图像对应的融合权重
$C[?]$是concatenation，即维度通道拼接。$P(?)$代表自适应像素权重生成模块。
然后分别将源图与对应的权重相乘并相加，随后归一化融合图像：


最后，将融合图像输入目标检测网络得到检测结果：
