**ImageCorners.jl** provides corner detection algorithms for images. There are 4 different algorithms that are present currently in the repository mentioned below:

- Harris
- Shi-Tomasi
- Kitchen-Rosenfeld
- Fast-Corners

Corners can be found to pixel and subpixel precision based on these algorithms using API of imcorner and imcorner\_subpixel respectively.

### Example:

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

julia> img = testimage("mandrill");

# corner detection using harris method
julia> corners = imcorner(img; method = harris);

# threshold can be specified for the thresolding the corner pixels
julia> corners = imcorner(img, 0.001; method = harris);

julia> corners = imcorner(img, Percentile(98.5); method = harris);

# for corner detection to subpixel precision imgcorner_subpixel can be used
julia> corners = imcorner_subpixel(img; method = harris);

```

There are several other algorithms we want to implement like Moravec, SUSAN, Forstner to reach feature parity with other solutions. We welcome new contributors to help improve the package.
