Graph-Based 方法中,采用RGB颜色空间,把图像中的每个像素用五个分量来表示,例如一个像素I表示为I(X,Y,R,G,B),在构造带权无向图时,把图像的每个像素看成图的节点,边的权值代表该条边所连接的两个像素的颜色特征差异,其边的权值用R,G,B的欧式距离来计算,如图2所示: 其中,v1,v2表示两个像素,R,G,B分...
The method, starting from a single source element, proceeds with a specific propagation mechanism based on the graph theory, to find a Minimum Path Spanning Tree (MPST). As compared with other existing segmentation methods, a new cost function is here proposed. It allows the process to be ...
The segmentation-based method can be used on spectrograms generated by both the radar and the camera to extract vital sign readings. The processing flow is demonstrated in Fig. 4. Figure 4 The flowchart of the graph-based image segmentation for layered structures. Full size image Ethical ...

Abstract This paper addresses the problem of segmenting an image into regions. We define a predicate for measuring the evidence for a boundary between two regions using a graph-based representation of the image. We then develop an efficient segmentation algorithm based on this predicate, and show ...
This work aims to address the challenges of video action segmentation and recognition utilizing graph models. To do this, we present a graph-based method named Semantic 2 Graph. 本研究旨在利用图模型解决视频动作分割与识别的挑战。为此,我们提出了一种基于图的方法,称为Semantic 2 Graph。
camera-based 3D Object Detection 基于相机的3D目标检测方法在学术界和工业界越来越受到关注,这主要是因为与LiDAR相比,相机传感器的成本显著降低[49]。早期方法[3, 46, 60]主要关注在2D目标检测器中增加额外的3D边界框回归头。自从LSS[40]通过“提升,涂抹”(Lift, splat)将多视图信息统一到鸟瞰图(BEV)上以来,基...
