bspline_convolve#
- scarlet2.wavelets.bspline_convolve(image, scale)[source]#
Convolve an image with a bpsline at a given scale.
This uses the spline h1d = jnp.array([1.0 / 16, 1.0 / 4, 3.0 / 8, 1.0 / 4, 1.0 / 16]) from Starck et al. 2011.
- Parameters:
image (
2D array) – The image or wavelet coefficients to convolve.scale (
int) – The wavelet scale for the convolution. This sets the spacing between adjacent pixels with the spline.
