edge pixel meaning in Chinese
边缘像素
Examples
- For the sake of sparseness of edge pixels , the matching area may big enough to find an accurate corresponding edge pixel
由于边缘点的稀疏，匹配时选用的区域可以大些，可以得到准确的匹配点。 - Comparing the output images , i select canny operator as optimizing edge detection operator . this paper emphasizes on stereo matching . firstly , selecting objects " edge pixels as matching elements
应用canny边缘检测后得到的图像边缘点作为匹配基元，在另一幅边缘图像中搜索对应点。 - But the detection speed is quite low . and edge pixels and strong noise are ignored entirely , or segmented to change type or unchanged type randomly , so that the detection precision is sure to be affected
但是运算量大,速度慢,同时又忽略差异图象边缘像素和强噪声点,或简单地判给变化或非变化类别,给图象变化检测精度带来一定程度的影响。 - 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。 - After this processing , we could obtain most edge pixels " corresponding pixels and maximum of disparity . in order to make up for the sparseness of edge pixels , a new matching algorithm named census is introduced , which based on neighbor pixels " correlativity
边缘特征点的稀疏造成物体深度信息的严重缺乏，为了弥补信息缺乏的不足，本文提出了在边缘点特征匹配的基础上应用census提取像素邻域特征进行立体匹配。
