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
: 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. plot-digitizer-matlab
Regardless of the specific tool, the process generally follows these steps: Scalar plot digitizer - File Exchange - MATLAB Central Several powerful MATLAB-based tools and blog resources exist
: This tool uses an automated algorithm that can trace a graph from an initial point, picking the nearest point to the previously digitized one to speed up the process. Key Tutorials and Blog Resources It features a GUI that allows you to
