摘要： The present invention is a motion adaptive spatial filtering(MASF) method for use with a image coding apparatus, which proceeds the temporal band-limitation of the video frame signals on spatial domain along the trajectory of a moving component without temporal aliasing by using a filter having a band-limitation characteristic according to a cutoff frequency. It is well known that video signal may contain a lot of temporal aliasing components because of insufficient frame sampling rate. And it is impossible to design band-limiting temporal filter simply by convolving a sequence of frames along the temporal direction. From a signal processing point of view, the aliasing degrades filter characteristics. This filtering method takes advantage of the fact that, if motion of each pixel is known, the temporal filtering can be performed in the spatial domain filtering along its trajectory. That results in de-aliasing characteristic.
摘要翻译：本发明是一种与图像编码装置一起使用的运动自适应空间滤波（MASF）方法，其通过使用滤波器沿着运动分量的轨迹在空间域上进行视频帧信号的时间带限，而没有时间混叠具有根据截止频率的频带限制特性。众所周知，由于帧采样率不足，视频信号可能包含大量的时间混叠分量。简单地通过沿着时间方向卷积帧序列来设计带限制时间滤波是不可能的。从信号处理的角度来看，混叠降低了滤波器特性。这种滤波方法利用了如下事实：如果每个像素的运动是已知的，则可以沿着其轨迹在空间域滤波中执行时间滤波。这导致去锯齿特性。
