Motion compensation and multiresolution coding
Signal Processing: Image Communication, 1994Abstract Multiresolution techniques have become more and more appealing in current image coding. Image multispectral representation produces many important features such as spectral shaping of coding noise according to human eye perception, good image energy compaction, coder tuning with respect to any band characteristics, and allows for multilevel ...

IEEE Transactions on Circuits and Systems for Video Technology, 2007
In this work, we develop a new motion-compe (MC) interpolation algorithm to enhance the temporal resolution of video sequences. First, we propose the bilateral motion estimation scheme to obtain the motion field of an interpolated frame without yielding the hole and overlapping problems.

Analysis of motion-compensated temporal filtering versus motion-compensated prediction
SPIE Proceedings, 2005In previous work, a performance bound for multi-hypothesis motion-compensated prediction (MCP) has been derived based on a video signal model with independent Gaussian displacement errors. A simplified form of the result is derived in this work. A performance bound for optimal motion-compensated temporal filtering (MCTF) has also been proposed based on

International Broadcasting Convention - IBC '94, 1994
Matteing and chroma-key are well-known techniques in frequent use in television production. When they are used, it is generally necessary to ensure that the camera remains stationary in order for the inserted picture material to remain in the correct position with respect to the foreground picture material.

Motion compensated vector quantization
ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Two algorithms combining vector quantization with motion compensation for data reduction are presented. The vector quantization technique used in the algorithms is a mean residual vector quantizer (MRVQ) with 8-bit mean, and the motion compensation technique is a simple block matching algorithm.

Motion compensated beamforming
Oceans 2003. Celebrating the Past ... Teaming Toward the Future (IEEE Cat. No.03CH37492), 2003A sea-water range and test environment is constructed in which multiple acoustic sources are moving along varied trajectories. The aggregate acoustic signal is measured with a planar array consisting of 120 hydrophones. A system of independent tracking arrays is used to provide ancillary positional information for each source.

Intelligent motion compensation
2014Nowadays, Computer-Aided Design and Computer-Aided Manufacturing ( CAD / CAM ) systems are widely used in industries, such as mould-making and mechanical components manufacturing on Computer Numerical Con-trolled (CNC) machine. VVorkpiece localization, with novel applications such as workpiece setup, refixturing and dimensional inspections, is a ...

Motion compensated image interpolation
IEEE Transactions on Communications, 1990Field skipping is a variable technique for reducing drastically the bit rate necessary to transmit a television signal. All fields have to be reconstructed at the receiver end, but nearest-neighbor or linear interpolations give poor performances when significant scene activity is present; therefore, some motion compensation scheme is mandatory ...

Intensity controlled motion compensation
Proceedings DCC '98 Data Compression Conference (Cat. No.98TB100225), 2002A new motion compensation technique that allows more than one motion vector inside each block is introduced. The technique uses the intensity information to determine which motion vector to apply at any given pixel. An efficient motion estimation algorithm is described that finds near optimal selections of motion vectors.

Motion Compensation in Emission Tomography
2012With the ever-improving spatial resolution available in single photon emission computed tomography (SPECT) and, especially, in positron emission tomography (PET), the unavoidable organ and subject motion is becoming one of the dominant factors limiting the practically achievable spatial resolution in the tomographic images.
