ConvolutionKernel

class lsst.images.convolution_kernels.ConvolutionKernel

Bases: ABC

An abstract base class for spatially-varying convolution kernels.

Attributes Summary

bounds	The region where this convolution kernel is valid (Bounds).
kernel_bbox	Bounding box of all images returned by compute_kernel_image (Box).

Methods Summary

compute_kernel_image(*, x, y)	Evaluate the kernel at a point.
serialize(archive)	Serialize the kernel to an output archive.

Attributes Documentation

bounds

The region where this convolution kernel is valid (Bounds).

kernel_bbox

Bounding box of all images returned by compute_kernel_image (Box).

Methods Documentation

abstract compute_kernel_image(*, x: int, y: int) → Image

Evaluate the kernel at a point.

Parameters

x

Column position coordinate to evaluate at.

y

Row position coordinate to evaluate at.

Returns

Image

An image of the kernel, centered on the center of the center pixel, which is defined to be (0, 0) by the image’s origin.

abstract serialize(archive: OutputArchive[Any]) → ConvolutionKernelSerializationModel

Serialize the kernel to an output archive.

Parameters

archive

Archive to write to.
