: One of the most popular and long-standing utilities for extracting data points from image files (BMP, JPG, TIF, GIF, and PNG). It features a GUI that allows you to calibrate axes by selecting four points and then "grab" data points by clicking along the curve.

: For those looking to automate the process, Steve Eddins’ blog post Automating Data Extraction provides a deep dive into using the Image Processing Toolbox to extract data from line plots. plot-digitizer-matlab

: Detailed walkthroughs for tools like Gravit (or GRABIT) demonstrate how to load images, calibrate linear or log axes, and export data directly to the MATLAB workspace. General Digitization Workflow : One of the most popular and long-standing

Several powerful MATLAB-based tools and blog resources exist for digitizing (extracting data from) plots in images. The most effective approach typically involves using specialized GUI tools from the MATLAB Central File Exchange . Top MATLAB Plot Digitization Tools : Detailed walkthroughs for tools like Gravit (or
