摘要
基于传统算法,提出了一种增强的运动自适应去隔行算法.在第一步运动检测得出运动状态之后用中值检测来纠正运动误判,提高了运动检测的抑制噪声能力.其次,由检测结果进行运动自适应插值:对图像静止部分使用场间插值,对运动部分使用边缘自适应插值.实验结果表明,该算法提高了运动检测的准确性,对静止图像和动态图像均能达到较好的效果.在一定程度上克服了传统算法带来的运动模糊、边缘锯齿等问题,同时与运动补偿算法相比,具有易于硬件实现的优点.
An enhanced motion -adaptive de -interlacing algorithm based on conventional al- gorithm is presented. After getting the first motion state by motion detection,a median detection is used to correct false motion judgement to suppress the noise. Then according to the detection result, the motion - adaptive interpolation is used for static and motion parts. Experiment results show that the proposed method improves the accuracy" of motion detection and achieve better effects for both static and motive images. It overcomes disadvantages of blurring, serration, etc. of the existed algorithms. The motion compensation algorithm is also compared with the proposed method, which proves its convenience for hardware implementation.
