抽样点 meaning in English

sample point

In order to improve the efficiency , we use the sampling points of the sequences to compute the distance of two sequences . the distance of sampling points is used to filter the sequence of the database , so the similarity searching space is reduced and the efficiency of the query is improved
在保持序列变化模式的前提下，使用抽样点来计算序列之间的dtw距离，并依据抽样比率和查询参数选择过滤距离对序列数据库进行过滤，实验结果表明，抽样过滤的方法明显提高了查询效率。
We sample from parallel edges in equal distance , and we sample again from sample points set by slope and get fitting points set , then we use least square method to fit straight line with the fitting points set . the edges of paper currency image can be detected accurately and quickly by above method , and it is valid to some image with a certain defection
边缘检测采用了对平行边缘整体等间隔抽样,根据斜率对抽样点集进行再次抽样后得到拟和点集,用最小二乘法根据拟和点集拟和直线的方法,可以快速精确的检测到纸币边缘,并且能够处理边缘有一定程度残缺的纸币图像。
