: Specifically designed to digitize X-Y scatter plots from pictures. It is frequently updated and used for basic 2D data extraction.

: 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

: 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. : Specifically designed to digitize X-Y scatter plots

: 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 : One of the most popular and long-standing
