Graffiti Detection Using a Time-Of-Flight Camera
نویسندگان
چکیده
Time-of-Flight (TOF) cameras relate to a very recent and growing technology which has already proved to be useful for computer vision tasks. In this paper we investigate on the use of a TOF camera to perform video-based graffiti detection, which can be thought of as a monitoring system able to detect acts of vandalism such as dirtying, etching and defacing walls and objects surfaces. Experimental results show promising capabilities of the proposed approach, with improvements expected as the technology gets more mature.

Abnormality Detection in a Landing Operation Using Hidden Markov Model
The air transport industry is seeking to manage risks in air travels. Its main objective is to detect abnormal behaviors in various flight conditions. The current methods have some limitations and are based on studying the risks and measuring the effective parameters. These parameters do not remove the dependency of a flight process on the time and human decisions. In this paper, we used an HMM...

متن کاملA New Vision-Based and GPS-Signal-Independent Approach in Jamming Detection and UAV Absolute Positioning Assessment
The Unmanned Aerial Vehicles (UAV) positioning in the outdoor environment is usually done by the Global Positioning System (GPS). Due to the low power of the GPS signal at the earth surface, its performance disrupted in the contaminated environments with the jamming attacks. The UAV positioning and its accuracy using GPS will be degraded in the jamming attacks. A positioning error about tens of...
متن کاملGPS Jamming Detection in UAV Navigation Using Visual Odometry and HOD Trajectory Descriptor
Auto-navigating of unmanned aerial vehicles (UAV) in the outdoor environment is performed by using the Global positioning system (GPS) receiver. The power of the GPS signal on the earth surface is very low. This can affect the performance of GPS receivers in the environments contaminated with the other source of radio frequency interference (RFI). GPS jamming and spoofing are the most serious a...
متن کاملFace Detection using 3-D Time-of-Flight and Colour Cameras
This paper presents a novel method to apply standard 2-D face detection methods on 3-D data. The procedure uses a sensor setup consisting of a 3-D time-of-flight camera and a colour camera. At first, face detection is performed on the less structured and low-resolution 3-D range image. Only for those areas regarded as faces on the 3-D range image, processing continues on the corresponding high-...
