Examples
- The edge of a group of blood is visible and easy to track . there is little distortion of the shape of a group of blood between two frames . there are many methods to measure blood velocity such as optical flow techniques [ 40 , 44 , 45 ] , using fluorescent images [ 42 ] , template matching method [ 17 ] and so on [ 43 ]
大血管的情况复杂一些，第一类血管的血液和周围的组织都很复杂（见图3 . 1 ） ，这类血管有些血液和组织还很相似，特征是流速比较低，细胞团块边缘清晰，在一定时间内的形变较小，本文用模板匹配法，较好的测量出这类血液的流速。 - By qualitative contrast between this two methods , explain wavelet transform edge detection algorithm detects the image that have edge distinct , fine , fight to chirp performance strong etc . besides , through trailing and distill for the flaw image after pretreatment , line draft join etc . processing method , can realize the quantitative analysis for the physical features such as length and the location of flaw
通过对这两种方法的定性对比，得出小波变换边缘检测算法检出的图像具有边缘清晰、细腻，抗噪性能强等特点。此外，通过对预处理后的疵病图像采用跟踪提取，线条拟合等处理方法，可实现对疵病的位置、长度等物理特征的定量分析。
