DIGITIZEIMG2 Starts a GUI for digitizing graphs.
Can be used for multiple data sets per graph and NOs
if a data point is marked incorrectly.
Follow the instructions of the GUI.
RIGHT CLICK: Choose data point
LEFT CLICK: Finish
MIDDLE MOUSE BUTTON: NO of the last data point
opens an file picker. Can only be used on data types that are
compatible with IMREAD.
After choosing a file, a GUI will open that will guide you through
the steps required for extracting the data.
If called without outputs, the data is saved in a MAT
ImgData = digitizeImg2;
Saves the data in the matrix/struct ImgData (struct if more than one data set).
To choose the file directly.
