Struct Mat_

Source

pub struct Mat_<T> { /* private fields */ }

Expand description

docs.opencv.org

This struct is freely convertible into and from Mat using into and try_from methods. You might want to convert Mat to Mat_ before calling typed methods (like at, data_typed) when more performance is required because this way you will skip the data type checks.
