User guide#
Start with resize#
The stable product surface is regular-grid N-D resizing with explicit coordinates and projection antialiasing.
Resize
Choose methods, geometry, axes, boundaries, and reusable plans.
Five-minute quickstart
Downsample an array and select spatial axes safely.
Continuous models#
TensorSpline is a separate, stabilizing abstraction for evaluating a
continuous tensor-product spline at arbitrary coordinates.
TensorSpline
Construct and query continuous spline models with multiple bases and extension modes.
Research modules#
The following modules are experimental. Their APIs and validation contracts may still change.
Affine
Spline-evaluated 2-D and 3-D affine transforms.
Differentials
Gradients, Laplacians, and Hessian features.
Smoothing
Fractional smoothing and related research methods.
Adaptive regression
Sparse one-dimensional piecewise-linear models.
Multiscale
Spline pyramids and wavelets.
