Kernel

A class representing an image kernel for image processing, such as convolution or filtering operations in brain images.

Slots

width

A numeric value representing the width of the kernel in voxels. The width is typically an odd number to maintain symmetry.

weights

A numeric vector containing the weights associated with each voxel in the kernel.

voxels

A matrix containing the relative voxel coordinates of the kernel. Each row represents a voxel coordinate as (x, y, z).

coords

A matrix containing the relative real-world coordinates of the kernel, corresponding to the voxel coordinates.
