extracted edges meaning in English
抽取边缘
Examples
- This algorithm carries out pretreatment of ordinary military graphs , then segments images , extract edges in the margin , and finally conducts feature matching
该算法实现了对普通军事图像的预处理,然后进行图像分割、提取边缘,最后进行了特征匹配。 - Since edges in images possess very important information about objects in image processing and analyzing , how to extract edges effectively and rapidly becomes an imperative issue
在图像处理和图像分析中，图像中的边缘包含了重要的图像信息，因此如何有效快速地提取图像中的边缘是一个十分重要的问题。 - To effectively extract edges , edge pixels are classified according to the difference of intensity distribution , and multiple effective edge features are defined . edges are detected by applying fuzzy reasoning ( min - max centroid method ) , based on local image edge characteristics
该方法在重新定义边缘特征的基础上，引入模糊推理理论，从而形成了基于多边缘特征和模糊推理的边缘检测方法。 - First , the source image was decomposed by wavelet lifting , using mathematical morphological method extracts edges in low - frequency approximate image and using wavelet transform method extracts edges in high - frequency detailed images on the different levels , then the two edge images were fused according to some fusion rules to obtain an integrated and clear edge image
对源图像进行小波分解，用数学形态学法对低频子图像进行边缘检测，用小波变换法对不同分解层上的高频子图像进行边缘检测，采用一定的融合规则将这两个边缘图像融合在一起得到一幅完好的边缘图像。 - The method we designed first selects local area with typical object and extracts edge information from these object , then feature points is matched using a criterion combined with edge shape and gray - level information . in such steps , we obtain robust and steady control point using for image registration
本文描述的方法通过选取图像中的典型区域，利用地物特点提取边缘特征，并利用边缘形状信息和局部灰度统计信息结合作为特征点提取及同名点匹配的判别准则，可得到符合地物性质及直观认识的匹配特征点。
