The invention generally provides a method and apparatus for up-converting the frame rate of a digital video signal, the method comprising: receiving a digital video signal containing a first frame and a second frame; finding in one of the received frames, matches for objects in the other of the received frames; utilising 3 dimensional position data in respect of the objects within the frames to determine 3 dimensional movement matrices for the matched objects; using the 3 dimensional movement matrices, determining the position of the objects in a temporally intermediate frame and thereby generating an interpolated frame, temporally between the first and second frame.


Performance improvement of a 3d reconstruction algorithm using single camera images
Kılıç, Varlık; Platin, Bülent Emre; Department of Mechanical Engineering (2005)
In this study, it is aimed to improve a set of image processing techniques used in a previously developed method for reconstructing 3D parameters of a secondary passive target using single camera images. This 3D reconstruction method was developed and implemented on a setup consisting of a digital camera, a computer, and a positioning unit. Some automatic target recognition techniques were also included in the method. The passive secondary target used is a circle with two internal spots. In order to achieve...

In this study, we propose a heuristic methodology for modeling the end-to-end distortion characteristics of an error resilient broadcast system for 3D video overDigital Video Broadcasting -Handheld (DVB-H). We also use this model to optimally select the parameters of the video encoder and the error correction scheme, namely, Multi Protocol Encapsulation Forward Error Correction (MPE-FEC), minimizing the overall distortion. The proposed method models the RQ curve of video encoder and performance of channel c...
Loosely Coupled Kalman Filtering for Fusion of Visual Odometry and Inertial Navigation
Sirtkaya, Salim; Seymen, Burak; Alatan, Abdullah Aydın (2013-07-12)
Visual Odometry (VO) is the process of estimating the motion of a system using single or stereo cameras. Performance of VO is comparable to that of wheel odometers and GPS under certain conditions; therefore it is an accepted choice for integration with inertial navigation systems especially in GPS denied environments. In general, VO is integrated with the inertial sensors in a state estimation framework. Despite the various instances of estimation filters, the underlying concepts remain the same, an assume...
Method and apparatus for the detection and classification of occlusion regions
Günyel, Bertan; Alatan, Abdullah Aydın (EPO, 2011)
In frame rate up-conversion for video signals interpolated frames are inserted within the video stream to increase the frame rate for display. Halo effects, observed as ghost replicas, can occur in occlusion regions around the boundaries of moving objects. To enable the occlusion regions to be compensated, they are detected by a method utilizing forward, backward and bidirectional motion vectors for each of a first frame (100), a second frame (104) and an interpolated frame (102). Occlusion regions (106,108...
3D Object Modeling by Structured Light and Stereo Vision
Ozenc, Ugur; Tastan, Oguzhan; GÜLLÜ, MEHMET KEMAL (2015-05-19)
In this paper, we demonstrate a 3D object modeling system utilizing a setup which consists of two CMOS cameras and a DLP projector by making use of structured light and stereo vision. The calibration of the system is carried out using calibration pattern. The images are taken with stereo camera pair by projecting structured light onto the object and the correspondence problem is solved by both epipolar constraint of stereo vision and gray code constraint of structured light. The first experimental results s...
