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.
