This paper introduces a new database of freely available stereo-3D content designed to facilitate research in stereo post-production. It describes the structure and content of the database and provides some details about how the material was gathered. The database includes examples of many of the scenarios characteristic to broadcast footage. Material was gathered at different locations including...
In this paper we present a method to automatically introduce temporal consistency into a sequence of meshes reconstructed from multi-view video. We combine a number of advantages of previous work to produce a robust algorithm. Our approach uses SIFT features in each camera view combined with geometric information to produce accurate frame to frame correspondence. Coupling this with both volumetric...
Optical flow methods, such as Lucas-Kanade and Horn-Schunck algorithms, are popular in motion estimation. However, they fall short on accuracy when they are applied to blurred videos. Some people utilize hybrid camera system to get a low resolution image to suppress the blurring effect so that more accurate optical flow for blurred high resolution image can be further derived, though in most of the...
It is now the case that well-performing flash LIDAR focal plane array devices are commercially available. Such devices give us the ability to measure and record frame-registered 3D point cloud sequences at video frame rates. For many 3D computer vision applications this allows the processes of structure from motion or multi-view stereo reconstruction to be circumvented. This allows us to construct...
Video stabilization is used to eliminate unwanted shakiness in video caused by movement of the camera. This can be achieved by estimating the motion of the camera, filtering out the high frequency components in the motion path and warping the video frames in order to compensate for the motion. In this paper, an adaptive parameterization technique is proposed to define the characteristics of the filter...
This paper deals with automatic characterization of video capture actions like scale change (zoom) or translation (traveling) in a video sequence. The overall objective is to enhance the scripted quality while capturing a video sequence by professionals or non professionals. Ultimately, the capture actions would use a predefined video template, progressively filled by the cameraman and automatically...
The current proliferation of Unmanned Aircraft Systems provides an increasing amount of full-motion video (FMV) that, among other things, encodes geospatial intelligence. But the FMV is rarely converted into useful products, thus the intel potential is wasted. We have developed four concept demonstrations of methods to convert FMV into more immediately useful products, including: more accurate coordinates...
Decreasing traffic accidents and events are one of the most significant responsibilities for most of the government in the world. Nevertheless, it is hard to precisely predict the traffic condition. In order to understand the real cause of traffic accidents and restore the occurrence of traffic events, a traffic monitor and event analysis mechanism based on 3D video processing techniques is proposed...
A wireless tracking and controlling the mobile robot using video capturing feature (VCF) for unmanned applications is presented. It is a wheel-based and Radio frequency (RF wireless communicated) is used for communication between controller and the robot. The available motions of the robot are forward, backward, right, left and the combination of these movements. Besides, a camera is built in the...
This paper presents a method of generating new view point movie for the baseball game. One of the most interesting view point on the baseball game is looking from behind the catcher. If only one camera is placed behind the catcher, however, the view is occluded by the umpire and catcher. In this paper, we propose a method for generating a see-through movie which is captured from behind the catcher...
Augmented reality aims to insert virtual objects in real scenes. In order to obtain a coherent and realistic integration, these objects have to be relighted according to their positions and real light conditions. They also have to deal with occlusion by nearest parts of the real scene. To achieve this, we have to extract photometry and geometry from the real scene. In this paper, we adapt high dynamic...
We propose a robust background subtraction method for multi-view images, which is essential for realizing free viewpoint video where an accurate 3D model is required. Most of the conventional methods determine background using only visual information from a single camera image, and the precise silhouette cannot be obtained. Our method employs an approach of integrating multi-view images taken by multiple...
A signature verification system based on video is proposed in this paper.The signature information is obtained from video of camera which is different from traditional online or offline method.First,we set the camera in upper front of the white written paper,so that we can get the signatures have the most identifiability for human recognition. We locate the pen tip position using a contour-based method...
Scene change detection is an essential step for archived films restoration. But the image quality of archived films often degrades gradually which makes false detection during shot segmentation. This paper focuses on some problems about the scene change detection in archived films. For abrupt change shot detection, the difference between histograms of block-bases adjacent frames and across frames...
Most of the TV manufacturers have released 3DTVs in the summer of 2010 using shutter-glasses technology. 3D video applications are becoming popular in our daily life, especially at home entertainment. Although more and more 3D movies are being made, 3D video contents are still not rich enough to satisfy the future 3D video market. There is a rising demand on new techniques for automatically converting...
A digital video is composed of a series of frame images. The continuous rotation angles are computed using the frame images grabbed from the rotation angle measurement video. An angle is calculated with the cosine theorem through the center point, start point and object point in a frame image and is compensated to a rotation angle. The positions of the object point in frame images are different during...
In this paper, we propose a novel approach for synchronizing multiple videos captured from common laparoscopic operations in simulation-based surgical training. The disparate video sources include two hand-view sequences and one tool-view sequence that does not contain any visual overlap with the hand views. The synchronization of the video is essential for further visual analysis tasks. To the best...
Metadata is considered vital in making sense of ISR sensor data because it provides the context needed to interpret motion imagery. For example, metadata provides the fundamental information needed to associate the imagery with location and time. But, more than that, metadata provides information that can assist in automated video analysis. This paper describes some of the ways that metadata can be...
In this paper, we proposed a novel video enhancement for moving-objects in the dusk environment based on mixed-mode processing which involves de-noising, moving object detection, and image enhancement. The basic strategy is to first calculate each pixel's motion vector and then check the magnitude of this motion vector to determine that the pixel belongs to foreground (i.e., moving object) or background...
Panoramic-image-based approach for representing environmental data has become a common method used by various virtual reality applications. It has many advantages over the traditional 3D modeling approaches, such as shorter generation times, faster rendering speeds, higher photorealism, and less storage needed. The drawback is however that it stores only static information of the scene. Panoramic...
