多模态特征交互与语义引导融合的RGB-T人群计数OA
Multimodal feature interaction and semantic guided fusion for RGB-T population counting
RGB-T模态人群计数旨在利用可见光RGB和热红外图像的互补性实现人群计数.针对RGB-T多模态人群计数方法在特征提取时,存在模态间信息交互不足、特征融合不充分,导致人群计数结果不准确的问题,提出了一种多模态特征交互与语义引导融合的RGB-T人群计数方法.设计堆叠小尺度卷积核作为主干网络分支,提取各单模态的粗特征;提出多模态特征交互模块,对RGB和热红外各模态进行特征精细提取,实现模态间信息交互,克服信息交互不足的缺点;设计语义引导融合模块,通过全局与局部特征引导融合,增强多模态人群特征语义相关性,以充分融合多元上下文信息,提高人群目标的识别能力;利用回归头生成人群密度图,并输出计数结果.实验结果表明:所提方法在公开RGBT-CC数据集上各评价指标均优于对比方法,相较于CMCRL方法,所提方法的均方根误差降低了31.12%,对不同场景下人群计数具有更高的准确率.
RGB-T mode crowd counting is designed to take advantage of the complementarity of visible RGB and thermal infrared image to achieve crowd counting.Aiming at the problems of insufficient information interaction between modes and insufficient feature fusion in the feature extraction of the RGB-T multimodal crowd counting method,an RGB-T crowd counting method based on multi-modal feature interaction and semantic guided fusion is proposed.Firstly,a stacked small scale convolution kernel is designed as a branch of the backbone network to extract the coarse features of each single mode.Secondly,in order to address the limited information interaction between the modes,a multi-modal feature interaction module is suggested.This module will extract the features of each RGB and thermal infrared mode and actualize the interactive features of the mode information.Then,a semantic-guided fusion module is designed to enhance the semantic relevance of multi-modal crowd features through global and local feature-guided fusion,so as to fully integrate multi-context information and improve the recognition ability of the target population.Finally,the regression head is used to generate the population density map and output the counting results.Experimental results demonstrate that the proposed method outperforms the comparison algorithms on the open RGBT-CC dataset,with a 31.12%reduction in the root-mean-square error value compared to the CMCRL method and higher accuracy for crowd counting under various scenarios.
