perspective transform meaning in English

透视变换

A fast non - iterative global motion estimation ( gme ) algorithm is disclosed for estimating the perspective transform global motion parameters from the motion vectors ( mv ) obtained from the block matching process that includes grouping a plurality of motion vectors in the input video stream into a predetermined number of groups of motion vectors , calculating a set of global motion parameters from each of the predetermined groups of the motion vector , and processing the set of global motion parameters generated from the calculation to obtain a final estimation
本发明系关于一种快速非反覆式全域移动估测方法，以由区块匹配程序中所获得的移动向量去估测一透视转换全域移动参数，其包含一分组步骤，将该输入影像资料流中的多个移动向量区分成具有预定数目的移动向量之群组?一计算步骤，系依据每一群组中之移动向量，求取该等群组之全域移动向量参数值?一处理步骤，系处理计算步骤中所计算出的每一群组之群组全域移动向量参数值，以获得一最后之全域移动向量。
