Jujiang turns an image of a plotted curve into calibrated time-series data. Crop the plot, enter the real ranges of the t and y axes, and it detects the curve; it then fits a polynomial model, computes Newton finite-difference layers, and renders the original, the captured trace, the projection and the difference depth, all annotated.
A prediction panel returns a value for any t you enter: a usable series recovered from a figure when the underlying data was never published.
- Crop, calibrate the axes, detect the curve
- Polynomial fit with Newton finite-difference layers
- Annotated original, trace, projection and depth views
- Prediction for any t
