cv-convert

Type conversions among famous Rust computer vision libraries. It supports the following crates:

• image
• imageproc
• nalgebra
• opencv
• tch
• ndarray

Usage

This crate allows crate version selection in Cargo features. For example, the feature nalgebra_0-30 enables nalgebra 0.30.x.

toml [dependencies.cv-convert] version = 'x.y.z' features = [ 'image_0-24', 'opencv_0-69', 'tch_0-8', 'nalgebra_0-31', 'ndarray_0-15', ]

The full feature was available before 0.20 but was removed since 0.21 to avoid bloating and surprising dependency update.

The minimum supported rustc is 1.51. You may use older versions of the crate (>=0.6) in order to use rustc versions that do not support const-generics.

Usage

The crate provides FromCv, TryFromCv, IntoCv, TryIntoCv traits, which are similar to standard library's From and Into.

```rust use cv_convert::{FromCv, IntoCv, TryFromCv, TryIntoCv}; use nalgebra as na; use opencv as cv;

// FromCv let cvpoint = cv::core::Point2d::new(1.0, 3.0); let napoints = na::Point2::::fromcv(&cvpoint);

// IntoCv let cvpoint = cv::core::Point2d::new(1.0, 3.0); let napoints: na::Point2 = cvpoint.intocv();

// TryFromCv let namat = na::DMatrix::fromvec(2, 3, vec![1.0, 2.0, 3.0, 4.0, 5.0, 6.0]); let cvmat = cv::core::Mat::tryfromcv(&namat)?;

// TryIntoCv let namat = na::DMatrix::fromvec(2, 3, vec![1.0, 2.0, 3.0, 4.0, 5.0, 6.0]); let cvmat: cv::core::Mat = namat.tryintocv()?; ```
