Utilities

This package provides some useful functions for diverse purposes, including type hint, image manipulation and computation, etc.

Creating grid

grid(n[, spacing, center, symmetric, broadcast])	Create a len(n)-D evenly spaced grid.
interval(n[, spacing, center, symmetric])	Create a 1D evenly spaced grid.

Image manipulation

crop(image, cropping)	Crop an image with given cropping width.
pad(image, padding[, mode, value])	Pad an image with given padding width.
resize(image, target_size[, mode, value])	Resize an image to given size by padding or cropping around its edges.
partition(image, n_patches[, overlap, ...])	Partition an image into patches, either overlapping or not.
partition_padded(image, n_patches[, ...])	Partition an image into patches, each of which is padded with pixels from neighbouring patches.
merge_patches(patches[, overlap, merge_method])	Merge a set of patches into an image.

External parameters

with_external([func, exclude])	A decorator to mark a method as having external parameters.
