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) are located by comparing bidirectional motion vectors with forward or backward motion vectors to find inconsistencies. Then blocks of pixels having bi directional motion vectors (112,114) can be compensated unidirectionally by using the pixel information (220,224) in one of the original frames (100,102).

Implementation of a distributed video codec
Işık, Cem Vedat; Akar, Gözde; Department of Electrical and Electronics Engineering (2008)
Current interframe video compression standards such as the MPEG4 and H.264, require a high-complexity encoder for predictive coding to exploit the similarities among successive video frames. This requirement is acceptable for cases where the video sequence to be transmitted is encoded once and decoded many times. However, some emerging applications such as video-based sensor networks, power-aware surveillance and mobile video communication systems require computational complexity to be shifted from encoder ...
Composite Method in Real Time Video Stabilization
Bayrak, Serhat; Ulusoy, İlkay (2009-01-01)
Since digital video stabilization completely performs over the images, if requires exhaustive processing power. Therefore, it is less preferred for real-time applications. Global (background) motion estimation in floating video is the most time consuming part of digital video stabilization. In this work, the load of digital motion estimation is reduced by using mechanical motion sensors, thus, it is shown that digital video stabilization can be used for real-time applications.
Method and Apparatus for Frame Interpolation
Alatan , Abdullah Aydın; Gedik, Osman Serdar (USP, 2010)
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, dete...
UTILIZATION OF EVENT BASED CAMERAS FOR VIDEO FRAME INTERPOLATION
Kılıç, Onur Selim; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2022-8-25)
Video Frame Interpolation (VFI) aims to synthesize several frames in the middle of two adjacent original video frames. State-of-the-art frame interpolation techniques create intermediate frames by considering the objects' motions within the frames. However, these approaches adopt a first-order approximation that fails without information between the keyframes. Event cameras are new sensors that provide additional information in the dead time between frames. They measure per-pixel brightness changes asynchro...
FRAME-RATE CONVERSION FOR MULTIVIEW VIDEO EXPLOITING 3D MOTION MODELS
Gedik, O. Serdar; Alatan, Abdullah Aydın (2010-09-29)
A frame-rate conversion (FRC) scheme for increasing the frame-rate of multiview video for reduction of motion blur in hold-type displays is proposed. In order to obtain high quality inter-frames, the proposed method utilizes 3D motion models relying on the 3D scene information extractable from multiview video. First of all, independently moving objects (IMOs) are segmented by using a depth-based object segmentation method. Then, interest points on IMOs are obtained via scale invariant feature transform (SIF...
