| 摘 要： | 为提高心肌肥大病理图像量化评估的效率,提出了基于Hough变换的计算机分析方法.首先对心肌纵切切片图像进行Hough变换,检测出心肌纤维走向.然后采集与心肌纤维走向相垂直方向上的灰度分布信息,用迭代阈值法分割出肌纤维区域与肌纤维间隙区域,测量肌纤维直径.t检验分析表明,用该方法得到的心肌纤维数目和平均尺寸与人工测量结果一致(P>0.05).

| Abstract: | To increase the efficiency for measuring the size of myocardium fibers in evaluation of myocardium hypertrophy,an analysis method for myocardium hypertrophy images was proposed based on Hough transform.With this method,Hough transform is performed on the image of myocardium fibers to detected the direction of the fibers.Lines perpendicular to the fiber direction are generated,on which the distribution of gray levels are collected.The lines are divided into low gray levels representing fiber widths and high gray levels reprensenting the gaps between the fibers.In this way,the number and the average width of fibers are measured.The t test results(P>0.05) show that there is no significant difference between the results measured with the proposed method and by hands. |
