Abstract: A method and system for filtering an image frame of a video sequence from spurious motion, comprising the steps of dividing the image frame and a preceding image frame of the video sequence into blocks of pixels; determining motion vectors for the blocks of the image frame; determining inter-frame transformation parameters for the image frame based on the determined motion vectors; and generating a filtered image frame based on the determined inter-frame transformation parameters; wherein the image frame is dived into overlapping blocks.
Abstract translation: 一种用于从伪运动滤波视频序列的图像帧的方法和系统，包括以下步骤：将图像帧和视频序列的先前图像帧分割成像素块; 确定所述图像帧的块的运动矢量; 基于所确定的运动矢量确定所述图像帧的帧间变换参数; 以及基于所确定的帧间变换参数生成滤波图像帧; 其中图像帧被划分成重叠块。
