: 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

: Specifically designed to digitize X-Y scatter plots from pictures. It is frequently updated and used for basic 2D data extraction. Regardless of the specific tool, the process generally

: 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. : One of the most popular and long-standing

: A modern app that handles various image formats and supports complex digitizations, including log-scaled, tilted, skewed, or polar plots. It can re-interpolate data to a specified sampling rate, which is useful for further analysis like surface interpolation.
