cv-convert

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

• image
• nalgebra
• opencv
• tch
• ndarray

Import to Your Crate

Add cv-convert to Cargo.toml to import most conversions by default.

toml [dependencies.cv-convert] version = "0.12" You can specify supported libraries to avoid bloating.

toml version = "0.12" default-features = false features = ["opencv", "nalgebra"]

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.

Cargo Features

• opencv
• opencv-clang-runtime: Enable clang-runtime in opencv crate. Useful if you get libclang shared library is not loaded on this thread! panic.
• image
• nalgebra
• tch

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()?; ```
