Activity recognition using multiplex limited penetrable visibility graph

Journal of the Mechanical Behavior of Biomedical Materials, 2021
To solve the dynamic problem of different activities in human activity recognition research, an activity recognition method based on a multiplex limited penetrable visibility graph is proposed. The 21 pressure values for each sampling are mapped to nodes in the first-layer network; then the average path length of nodes in the asynchronous periodic ...

Application of Deep Learning in Ground Penetrating Radar Image Recognition

2021 International Conference on Artificial Intelligence, Big Data and Algorithms (CAIBDA), 2021
In the traditional ground-penetrating radar image recognition methods, the recognition accuracy is not high, the recognition of complex targets is difficult, the recognition process is cumbersome, and the structural characteristics reflected by the measured data cannot be accurately judged.

Penetrating Abdominal Air Gun Injuries: Pitfalls in Recognition and Management

Annals of Emergency Medicine, 1995
Emergency health care providers often underestimate the potential for pellet and BB guns to inflict life-threatening penetrating injuries. We present four children with intraabdominal injuries caused by air guns and summarize the characteristics of 12 similar cases reported in the literature.

Influence of Sparse Contact Point and Finger Penetration in Object on Shape Recognition

IEEE Transactions on Haptics, 2020
Making a virtual object shape recognizable using a haptic display is one of the major themes of haptic research. In previous works, multipoint haptic displays have been developed that had a high contact point density between the users' finger skin and the virtual object.

Resonance based target recognition for ground penetrating radar

56th EAEG Meeting, 1994
The ability to detect voids with Ground Penetrating Radar (GPR) has been recognised as one of its strengths [Campbell et al., 1993]. This is of importance in civil engineering, building assessment, and archaeology. The dielectric difference between an air void and its soil/ground surround (dielectric half space) is sufficient to enable comparatively ...

Rolling penetrate descriptor for shape-based image retrieval and object recognition

Pattern Recognition Letters, 2009
This paper proposes a new approach called rolling penetrate descriptor for shape description. It combines the advantage of the contour-based and the region-based methods, and provides an unified scheme to handle various shapes. The main process of the proposed method is to use a set of scanning lines that rotate around the shape centroid to collect ...

A ground penetrating radar for soil pattern recognition

IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998
Ground penetrating radar (GPR) is a well-known technique which is used to provide an introspective view of the subsoil and has numerous commercial and scientific applications. This paper shows how a well designed GPR permits a proper analysis of the geophysical characteristics of the first few meters of soil to be made.

Cognitive Penetrability of Social Perception: A Case for Emotion Recognition

Review of Philosophy and Psychology, 2015
Adams & Kveraga argue that social visual perception is cognitively penetrable by extending a top-down model for visual object recognition to visual perception of social cues. Here I suggest that, in their view, a clear link between the top-down contextual influences that modulate social visual perception and the perceptual experience of a subject is ...

Image processing and pattern recognition in ground penetrating radar data

Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 1993
The task of detection of specific buried objects in ground penetrating radar (GPR) images is considered. A modification of the Hough transform (HT) is proposed and applied to this problem. Methods of texture analysis are used to determine the soil structure. The possibility of gaining information about the material of the buried object is examined. The
