| 1. | Figure 5 shows the edge points found after the tool runs the calipers 图五就是图四的卡钳运行后找到的边缘点。 |
| 2. | To the non - edge point , it ’ s variance is estimated by it ’ s adjacent non - edge points in the same area 对非边缘点的小波系数,它的方差由其相邻的在同一块区域的系数点决定。 |
| 3. | 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。 |
| 4. | In the post - processing for the edge points , the contour is found through the methods based on the mathematical morphology 在对边缘点的后处理中,我们采用了基于数学形态学的方法,得到了比较好的物体的外轮廓线。 |
| 5. | The found edge points are then applied to the line fitting tool which fits an infinite length line to the points . the fitted line is hown in figure 6 将找到的边缘点应用于拟合工具,进而形成一条无限长的直线。拟合后的直线如图六所示。 |
| 6. | 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。 |
| 7. | It analyses and studies the operating method in image processing area , including image division , image filter , picking up edge point , drawing up line and getting the distance of parallel lines 分析并研究了可用于指针图像处理的图像分割、图像滤波、边缘点提取、直线拟合、平行直线求距等运算方法。 |
| 8. | Upon that an efficient thinning algorithm based on borderline ( etab ) is proposed which treats with individual pixels point in each step and picks up unilateral edge points sequence as the framework of a character image 算法每一步都针对单个的像素点作处理,并提取笔划单侧边缘点序列作为字符图像骨架。 |
| 9. | Then a fast computing method is presented to estimate the curvature of edge points and the points at which curvature is less than some threshold are collected to fit lines 为提取直线边缘,使用改进的序列细化算法将边缘细化为单像素宽,而后用一种快速曲率估计方法估算边缘点的曲率,并保留估算值很小(约等于零)的点拟合直线。 |
| 10. | The external force given by the edge map makes the curve moving in the direction of the edge , hi traditional active contour the external force is the potential energy of the edge map , which has some insurmountable difficulties 外力是由图像的边界图给出,它使得曲线向着边界点移动。在传统的活动轮廓中,外力通常由边缘点的梯度势能场给出。 |
