Aiping Yang · Computer Engineering and Applications Journal · 2011
To use Block Matching Algorithm(BMA) based Motion Estimation(ME) in the Frame Rate Up Conversion(FRUC), always results in overlapping and hole problems.An improved algorithm of the 3-D Recursive Search block-matching(3DRS) for rate up conversion is presented.More accuracy motion estimation is performed with the 3DRS and bi-direction motion estimation.A vector median filter is applied to smooth motion vector field and the median filter motion compensation technolo-gy is used to interpolate the missing frames.Experimental results show that the proposed algorithm provides better performances both in subjective and objective factors,and due to low computation complexity,this algorithm can perform better real-time quality as well as be realized in hardware.
