sunpy.image.coalignment.match_template_to_layer(layer, template)[source]¶

Deprecated since version 4.0: The match_template_to_layer function is deprecated and may be removed in version 4.1. Use sunkit_image.coalignment.match_template_to_layer instead.

Calculate the correlation array that describes how well the template matches the layer. All inputs are assumed to be numpy arrays.

Parameters:

layer (numpy.ndarray) – A numpy array of size (ny, nx).
template (numpy.ndarray) – A numpy array of size (N, M) where N < ny and M < nx.

Returns:

numpy.ndarray – A correlation array between the layer and the template. The values in the array range between 0 and 1.
