Allow unitful kernels when filtering unitful AxisArrays

2

ref. https://discourse.julialang.org/t/images-kernel-sizes-and-imageaxes/ In the following example, the kernel size is calculated based on array indices, not the provided physical dimensions of the image. ``` using AxisArrays, Unitful julia> img =...

Internal error in Julia 1.8-rc1

1

An Julia internal error occurs during precompilation. More specifically, after disabling `include("precompile.jl")` the following is a way to reproduce the error ```julia juliaa> using ImageFiltering, OffsetArrays julia> A = OffsetArray([1.625,...

I'm assuming this is due to FFTW's auto planning making different decisions. If so, it would be good to expose the plan settings, if possible. I'm seeing unexplained significant slowdown...

Strange automagic kernel centering depending on eltype

```julia using ImageFiltering @assert imfilter( [0, 0, 1, 0, 0], [1, 1]) == [ 1, 1 , 0, 0 , 0] @assert imfilter(Float64[0, 0, 1, 0, 0], [1, 1]) ≈...

possible performance improvement to `mapwindow`

5

Didn't explore it in depth, but the following hand-written version in 5mins is faster than what `mapwindow` provides, so I believe there are still room for performance tweak: ```julia #...

Add Butterworth Filter

1

In response to feature request #240 Please let me know if there are any fixes to be done on the code.

When one needs to compute the sum/average of all blocks extracted from an image, pre-building the integral array usually provides a more efficient computation. ``` using BenchmarkTools, IntegralArrays # simplified...

Butterworth Kernel?

3

Hi, I can't find a butterworth kernel in the Images, and think would be a nice addition to the package. The `DSP.jl` do have a Butterworth filter design, maybe could...
