What is the equivalent Julia function of the Wolfram Mathematica **ImagePartition** function ( ImagePartition—Wolfram Language Documentation )

Take a look at GitHub - JuliaArrays/TiledIteration.jl: Julia package to facilitate writing mulithreaded, multidimensional, cache-efficient code, which handles N-dimensional arrays (including images).

A basic version:

```
using Images
using TestImages
img = testimage("cameraman")
"""
Partitions an image into an array of subimages
of pixel width w and pixel height h.
"""
function imblocks(img,
( w, h)::Tuple{Integer,Integer},
(dw, dh)::Tuple{Integer,Integer} = (0, 0))
x = (size(img, 2) - dw) ÷ w
y = (size(img, 1) - dh) ÷ h
[view(img, (1:h) .+ (i*h+dh), (1:w) .+ (j*w+dw)) for i=0:y-1, j=0:x-1]
end
"""
Partitions an image into an array of sxs-pixel subimages.
"""
imblocks(img, s::Integer) = imblocks(img, (s, s))
imblocks(img, (128,64))
```

Padding left as an exercise.
