This paper presents a novel occlusion handling frame rate up-conversion method. The proposed method consists of two main steps; true motion estimation and directionally adaptive motion compensated interpolation. In the true motion estimation step, forward and backward directed motion vectors are estimated and merged recursively in order to reliably estimate the occlusion regions without increasing the number of frame buffers. After acquiring a reliable motion vector field, motion compensated interpolation is done in the second step by determining the source directions under an OBMC framework. The experimental results show that the proposed approach improves the motion estimation / compensation performances and reduce the occlusion based halo artifacts compared to the conventional approaches.

Allpass variable fractional delay filters by pole loci interpolation Hacıhabiboğlu, Hüseyin (2010-04-15) A simple, accurate and efficient variable fractional delay (VFD) IIR filter is presented. The method is based on the interpolation of pole loci of maximally-flat allpass fractional-delay filters. The responses of the proposed VFD filter for different fractional delay values are simulated and the approximation errors are shown to be very small.
Symbolic polynomial interpolation using Mathematica Yazıcı, Adnan; Ergenc, T (2004-01-01) This paper discusses teaching polynomial interpolation with the help of Mathematica. The symbolic power of Mathematica is utilized to prove a theorem for the error term in Lagrange interpolating formula. Derivation of the Lagrange formula is provided symbolically and numerically. Runge phenomenon is also illustrated. A simple and efficient symbolic derivation of cubic splines is also provided.
2d polynomial interpolation: A symbolic approach with mathematica Yazıcı, Adnan; Ergenc, T (2005-01-01) This paper extends a previous work done by the same authors on teaching 1d polynomial interpolation using Mathematica [1] to higher dimensions. In this work, it is intended to simplify the the theoretical discussions in presenting multidimensional interpolation in a classroom environment by employing Mathematica's symbolic properties. In addition to symbolic derivations, some numerical tests are provided to show the interesting properties of the higher dimensional interpolation problem. Runge's phenomenon w...
Direct command generation for CNC machinery based on data compression techniques Yaman, Ulaş; Dölen, Melik (2013-04-01) This paper presents a direct command generation technique for digital motion control systems. In this paradigm, higher-order differences of a given trajectory (i.e. position) are calculated and the resulting sequence is compacted via data compression techniques. The overall method is capable of generating trajectory data at variable rates in forward- and reverse-directions with the utilization of a linear interpolator. As a part of the command generation scheme, the paper also proposes a new data compressio...
QUALITY EVALUATION OF STEREOSCOPIC VIDEOS USING DEPTH MAP SEGMENTATION Sarikan, Selim S.; Olgun, Ramazan F.; Akar, Gözde (2011-09-09) This paper presents a new quality evaluation model for stereoscopic videos using depth map segmentation. This study includes both objective and subjective evaluation. The goal of this study is to understand the effect of different depth levels on the overall 3D quality. Test sequences with different coding schemes are used. The results show that overall quality has a strong correlation with the quality of the background, where disparity is smaller relative to the foreground. The results also showed that con...
