cv-convert

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

Import to Your Crate

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

[dependencies.cv-convert]
version = "0.1"

You can manually choose supported libraries to avoid bloating.

version = "0.1"
default-features = false
features = ["opencv-4", "opencv-buildtime-bindgen", "nalgebra"]

Usage

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

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

// FromCv
let cv_point = cv::core::Point2d::new(1.0, 3.0);
let na_points = na::Point2::<f64>::from_cv(&cv_point);

// IntoCv
let cv_point = cv::core::Point2d::new(1.0, 3.0);
let na_points: na::Point2<f64> = cv_point.into_cv();

// TryFromCv
let na_mat = na::DMatrix::from_vec(2, 3, vec![1.0, 2.0, 3.0, 4.0, 5.0, 6.0]);
let cv_mat = cv::core::Mat::try_from_cv(&na_mat)?;

// TryIntoCv
let na_mat = na::DMatrix::from_vec(2, 3, vec![1.0, 2.0, 3.0, 4.0, 5.0, 6.0]);
let cv_mat: cv::core::Mat = na_mat.try_into_cv()?;
