一种运动自适应去隔行技术及其VLSI结构

提出一种有效的运动自适应去隔行算法.该算法通过对同极性的相邻场进行运动检测,把插值点所处的区域分为快速运动区域、慢速运动区域和静止区域,对不同的区域采用不同的插值算法.在边缘检测方面,采用改进型ELA算法克服了传统的ELA算法处理水平边缘方面的不足,使边缘得到有效保护.与运动补偿算法相比,该算法计算复杂度较低,易于VL...

A Motion Adaptive De-interlacing Technique and VLSI Architecture

An efficient motion adaptive de-interlacing is proposed in this paper.The mixing pixels is classified to fast motion,slow motion or static region according to the motion detection of the same parity field,the corresponding interpolation method is used in different motion region.The edge detection uses the improved ELA algorithm which overcomes the traditional ELA algorithm’s deficiency at processing horizontal edge,and the edge is preserved effectively.Compared with motion compensated algorithm,our proposed algorithm required lower computational complexity,and it is easier to implement by VLSI.The experiment shows that the proposed algorithm gains better de-interlacing and high peak signal-to-noise ratio.
