This method has the high accuracy rate for extracting the product price info. And group the product according to the similarity of product description. 通过使用这个方法,能够以较高的准确率抽取到商品价格信息,并根据其描述文本的相关程度,将商品进行分组。
According to such relation, the inverse distance power method is used to give the spatial interpolation to reveal the image rectification accuracy. Based on above, the visualizations of accuracy are used to give the detail description of the quality of image rectification. 依据距离倒数加权法空间插值理论,采用多种可视化方法对影像纠正的质量进行描述,便于更好地了解影像几何纠正整体精度,对控制点或纠正方法的选取起到一定的指导作用。
