Ankara : Department of Electrical and Electronics Engineering and the Institute of Engineering and Sciences of Bilkent University, 1996.Thesis (Master's) -- Bilkent University, 1996.Includes bibliographical references leaves 77-80.Novel regularized motion estimation techniques and their possible applications
to video coding are presented. A block matching motion estimation algorithm
which extracts better block motion field by forming and ininimizing a suitable
energy function is introduced. Based on ciri ¿idciptive structure onto block
sizes, cui cidvcinced block matching ¿ilgorithm is presented. The block sizes
are adaptively ¿idjusted according to the motion. Blockwise coarse to fine
segmentation based motion estimation algorithm is introduced for further
reduction on the number of bits that are spent lor the coding of the block
motion vectors. Motion estiiricition algorithms which can be used lor ¿iverage
motion determination and artificial frame generation by fractional motion
compensation are ¿ilso developed. Finallj^, an alternative motion estimation
cind compensation technique which defines feciture based motion vectors on the
ob ject boundciries and reconstructs the decoded frame from the interpolation of
the compensated object boundaries is presented. All the algorithms developed
in this thesis are simulated on recil or synthetic images cind their performance
is demonstrcited.Kıranyaz, SerkanM.S
