EXTRACTING 3D SEMANTIC INFORMATION FROM VIDEO SURVEILLANCE SYSTEM USING DEEP LEARNING
3-D space Camera calibration Target recognition Target tracking
2018/5/16
At present, intelligent video analysis technology has been widely used in various fields. Object tracking is one of the important part of intelligent video surveillance, but the traditional target tra...
REPRESENTING WITH LIGHT. VIDEO PROJECTION MAPPING FOR CULTURAL HERITAGE
video projection mapping cultural heritage laser scanning photogrammetry geoinformatics technologies architecture
2018/6/4
In this paper, we describe a cross-disciplinary process that uses photogrammetric surveys as a precise basis for video projection mapping techniques. Beginning with a solid basis that uses geoinformat...
PIXEL-BY-PIXEL ESTIMATION OF SCENE MOTION IN VIDEO
video sequence image processing moving object detection tracking recurrent procedures reverse processing
2017/6/19
The paper considers the effectiveness of motion estimation in video using pixel-by-pixel recurrent algorithms. The algorithms use stochastic gradient decent to find inter-frame shifts of all pixels of...
CHANGE DETECTION IN UAV VIDEO MOSAICS COMBINING A FEATURE BASED APPROACH AND EXTENDED IMAGE DIFFERENCING
change detection image differencing directed change mask video mosaicking image registration UAV
2016/11/23
Change detection is an important task when using unmanned aerial vehicles (UAV) for video surveillance. We address changes of short time scale using observations in time distances of a few hours. Each...
PRICISE TARGET GEOLOCATION AND TRACKING BASED ON UAV VIDEO IMAGERY
Video RTK Geolocation Kalman Filter Unmanned Aerial Vehicle
2016/11/15
There is an increasingly large number of applications for Unmanned Aerial Vehicles (UAVs) from monitoring, mapping and target geolocation. However, most of commercial UAVs are equipped with low-cost n...
THREE DIMENTIONAL RECONSTRUCTION OF LARGE CULTURAL HERITAGE OBJECTS BASED ON UAV VIDEO AND TLS DATA
3D reconstruction cultural heritage video image sequences terrestrial laser scanning unmanned aerial vehicle
2016/11/11
This paper investigates the synergetic use of unmanned aerial vehicle (UAV) and terrestrial laser scanner (TLS) in 3D reconstruction of cultural heritage objects. Rather than capturing still images, t...
LIDAR-INCORPORATED TRAFFIC SIGN DETECTION FROM VIDEO LOG IMAGES OF MOBILE MAPPING SYSTEM
Traffic Sign Detection Mobile Mapping System RANSAC Random Forest Camshift Kalman Filtering
2016/7/5
Mobile Mapping System (MMS) simultaneously collects the Lidar points and video log images in a scenario with the laser profiler and digital camera. Besides the textural details of video log images, it...
Video-Based Document Tracking: Unifying Your Physical and Electronic Desktops
Your Physical Electronic Desktops
2016/5/24
This paper presents an approach for tracking paper documents
on the desk over time and automatically linking them
to the corresponding electronic documents using an overhead
video camera. We demons...
This paper describes a mostly automatic method for taking the output
of a single panning video camera and creating a panoramic
video texture (PVT): a video that has been stitched into a single,
wid...
Video Puppetry: A Performative Interface for Cutout Animation
real-time animation tangible user interface vision
2016/5/24
We present a video-based interface that allows users of all skill
levels to quickly create cutout-style animations by performing the
character motions. The puppeteer first creates a cast of physical...
Tools for Placing Cuts and Transitions in Interview Video
Interaction Human-Computer Interfaces
2016/5/24
We present a set of tools designed to help editors place cuts and create
transitions in interview video. To help place cuts, our interface
links a text transcript of the video to the corresponding l...
We present a semi-automated technique for selectively deanimating
video to remove the large-scale motions of one or more
objects so that other motions are easier to see. The user draws
strokes to i...

2016/1/29
This paper considers how the use of video clips integrated into a virtual learning environment has been perceived by students on a land surveying module within a civil engineering degree. The increasi...
Triangulation-based Video Registration and Applications
disparity geo-referencing mosaicking registration reconstruction triangulation video
2016/1/25
We present a simple and effectient procedure for registration of video sequences onto high-resolution images for scenes with distinct
spatial depth. The high-resolution image could be a synthetic vie...
