How to get the data from a contour plot imagine in png

Hi,

I nedd to get the data out of a contour plot avalaible in png (or similar). Do you have any matlab code to suggest? There are many codes to take single data point from a xy graph image, but I am looking for a contour plot. I can see it should be possible, is there anything already developed?

Thank you,

Isabella

Hi,

As per my understanding, you have a “png” file and want to extract the contour data from the file. You can use the function “imcontour” to do this with the following syntax to get the contour data:

[C, h] = imcontour(___)
