Performance of Wavelet-based Multiresolution Motion Estimation for Inbetweeningin Old Animated Films
ThisÂ paperÂ investigates theÂ performanceÂ ofÂ wavelet-based multiresolutionÂ motionÂ estimation (MRME)Â forÂ inbetweeningÂ inÂ oldÂ animated filmsÂ usingÂ three differentÂ MRMEÂ schemes.Â TheÂ threeÂ schemesÂ are:Â coarse-to fine with a wavelet-based MRME, one of Zhangâ€™s MRMEs, and an MRME in the spatial domain.Â In order to make a performance comparison of these MRMEÂ schemes,Â twoÂ videoÂ sequences wereÂ usedÂ forÂ aÂ simulation.Â TheÂ experimental resultsÂ showÂ thatÂ theÂ coarse-to-fineÂ methodÂ performedÂ betterÂ thanÂ Zhangâ€™sÂ MRMEÂ andÂ theÂ MRME in the spatial domain. The evaluation resultsÂ on block size 9x9 indicate that the coarse-to-fine method had an average peak signal-to-noise ratio (PSNR) ofÂ 23.48 dB for the first sequence and 29.84 for the second sequence.
