Hi!
Need help on call to adaptive_threshold:
Line
let img3=adaptive_threshold(&imgg,1);
Issues error
= note: expected reference &image::buffer_::ImageBuffer<image::color::Luma<u8>, Vec<u8>>
found reference &ImageBuffer<Luma<u8>, Vec<u8>>
= note: perhaps two different versions of crate image are being used?
