2. 如何在区域内提取对口室感兴趣的物体
原标题:how to extract the objects inside the region of interest in matlab

我有兴趣在该区域内提取物体。

例如,

Fig1显示了我的激光特征的强度。 根据激光强度,我将情况划分为两个感兴趣的区域(ROI1和ROI2)。

图2显示,由于积极反应和激光强度简介,我所花成果重叠。 积极的回复数据文档由x和 y坐标组成。 你们可以看到,结果分散在激光形象上。

Here is what I want to do, I want to extract the spots within the ROI2 and discard all the rest as shown in Fig3. How can I do it? Specifically, how can I define a irregular shape ROI2 in matlab and extract the coordinates of positive response data. Thanks for the help.

我不知道你为你们的职司使用什么代表,但我想提出一些方法:

  1. 如果贵组织只是一纸空文,而且你知道,它只是适用于结果坐标。 签字是否在境内

  2. 如果您的ROI是某种聚合物,你可以使用inpolygon的功能。

  3. 你们可以让罗马尼亚广播公司接触黑白形象,很容易检测到的点击。

请提供更多有关监察员代表的详细情况。
