I need Matlab in julia…

I am not sure I understand what you are trying to do, but perhaps you are looking for

What I want to do is; How can I get the automatic Threshold of a july image?Automatic threshold of an image in matlab.

my project …

using ImageContrastAdjustment, Images, ImageFiltering, TestImages, ColorTypes, HistogramThresholding

const ICA = ImageContrastAdjustment

function example()

```
img = testimage("circulo")
# Grayscale image.
imgg = Gray.(img)
# Linear contrast stretching.
imggₗ = ICA.adjust_histogram(ICA.LinearStretching(), imgg)
# Histogram Equalization.
imggₑ = ICA.adjust_histogram(ICA.Equalization(), imgg)
#=
admiminsion and subtracion
=#
R₁ = float.(imggₗ) + float.(imggₑ)
R₂ = R₁ - float.(imggₑ)
# imggₗ + imggₗ + imggₑ.
R₃ = R₁ + R₂
# Applying a minimum filter.
window_size = (-1:1, -1:1)
imgmin = mapwindow(minimum, R₃, window_size)
# divide el intervalo del valor más pequeño al más grande en imgmin en 256 bin
edges, counts = ICA.build_histogram(imgmin, 256, minval = minimum(imgmin), maxval = maximum(imgmin))
#=
La matriz `count` almacena en el índice 0 las frecuencias que estaban por debajo de
primer borde del cubo. Ya que estamos buscando un umbral sobre el intervalo
divididos por `edges` necesitamos descartar la primera bandeja en` count`
de modo que las dimensiones de `edge` y` count` coincidan.
=#
t = find_threshold(Otsu(), counts[1:end], edges)
# Aplica el umbral a imgmin y checo el resultado.
img₀₁ = zeros(Gray{Bool}, axes(imgmin))
for i in CartesianIndices(img)
img₀₁[i] = imgmin[i] < t ? 0 : 1
end
display(img₀₁)
```

end

It is still not clear what you are asking here.

The original question seems to be about something general (interfacing Matlab and Julia), the second one is about programming a specific problem in Julia.

I am not sure how the two are related, or why you need Matlab for this.

The method you link should be very simple to implement in Julia (if not done already, I didn’t check). Perhaps you could contribute it to one of the image processing libraries as a PR.

Excuse me if I did not make sense, I think I love the nights I have not slept.

The code you provide is made in Juno.

but I’ve been searching the internet for matlab in julia … and I found a process, and I thought it would be good to install matlab.

But my code does the opposite of what I require.

and I want to use the otsu method in that image. Through Julia-matlab. Or if not well, it would be in Julia, in console form.

Maybe this package: https://github.com/zygmuntszpak/ImageBinarization.jl is what you’re looking for for the binarisation; it does implement Otsu.

(If you really want to use Matlab, you’ll want to use the interop package mentioned already)
