# [ImageFiltering.jl](https://juliaimages.org/ImageFiltering.jl/dev/)

ImageFiltering.jl supports linear and nonlinear filtering operations on arrays, with an emphasis on the kinds of operations used in image processing. The core function is `imfilter`, and common kernels (filters) are organized in the `Kernel` and `KernelFactors` modules.

### Example:

```julia-auto
julia> using ImageFiltering, TestImages

julia> img = testimage("mandrill");

julia> imgg = imfilter(img, Kernel.gaussian(3));

julia> imgl = imfilter(img, Kernel.Laplacian());

```

### Output:

## ImageFiltering v0.7.5

- Major reorganisation of documentation and improved docstrings which make the documentation more accessible. It had been common issue that was solved recently with @cormullion 's help(thank you!)

- Documentation link : [ImageFiltering.jl · ImageFiltering](https://juliaimages.org/ImageFiltering.jl/dev/)

Thanks @Ashwani_Rathee!

Tim Holy encouraged me to turn my complaint ([Suggestion: rewrite docstrings for usage rather than reference · Issue #1024 · JuliaImages/Images.jl · GitHub](https://github.com/JuliaImages/Images.jl/issues/1024)) into action, and also did a thorough review, for which, many thanks… 🙂
