You have a number of options. See https://www.mathworks.com/matlabcentral/fileexchange/?term=tag%3A%22digitize%22

Note: extracting the data is much easier if you have the data used to create the image. Second best is if the image is really a MATLAB figure with a plot() or patch() or surf() that the data can be extracted from. The contributions in the File Exchange are for the case where you are starting with an image file such as a .PNG or .JPG
