如何在图像中选择一个非矩形的ROI [英] how to select an not rectangular roi in an image

问题描述

我想用opencv打开一个图像并在其上选择一个非矩形的roi.或者至少能够存储我单击该图像的某些点的坐标.

总的来说，我想打开一个图像，单击一些点，将其存储在与图像文件名关联的文件中，然后按下按钮"a"或"b"，然后将该图像存储在文件中，类型为"a"或''b.我使用的是opencv，也许使用的是wxwidgets.但是我真的很陌生.
谢谢Advanced

推荐答案

您不需要opencv吗? ，您不能仅将列表点存储在文本文件中吗?并且此文本文件还可以具有某种标识符，以显示该文本文件与哪个文件相关联.您可以从中使用线段来创建选择..

you don''t need opencv for that ? , can''t you just store a list points in a text file ? and this text file can also have some kind of identifier showing to which file it is associated. you can use line segments from this to create selection ..
