Hi All,

I have a circular image from which I am extracting inner surface(Draw a ROI), I want to save the XY coordinates of the extracted image (ROI). ROI is yellow line. how I can save XY coordinates in TXT file or can I save this ROI file as .ROI file to open it using IMAGEJ software.

Please suggest me how I can save or create roi file from this ROI.

Image with ROI

Only ROI Image as binary image.

Sir,Thanks For you comments I have save the data from yellow line into a text file.

one thing more I want to implement is that I am calculating the inner boundary of circular shapes like you see yellow line in upper image. if the boundary is miss calculated can I correct it manually by mouse? I don't know how I can implement this to correct the yellow line manually? like I have draw a example

the yellow line should be on inner boundary but my code calculated it wrong. I want to write a script that enables me to manually correct this error . can you guide me how I can edit this yellow line in image manually
