OpenVX 1.3.1 Vision Conformant Implementation in Rust

Overview

rustVX is a complete, conformant implementation of the Khronos OpenVX 1.3.1 specification written in Rust. It provides a safe, fast, and portable vision processing framework with full Vision Feature Set support.

Features

• Complete OpenVX 1.3.1 API - All base and vision functions
• Vision Conformance - Passes Khronos CTS for Vision Feature Set
• Memory Safe - Rust's ownership model prevents use-after-free, data races
• SIMD Optimized - SSE2/AVX2/NEON vectorized kernels
• C API Compatible - Drop-in replacement for existing OpenVX applications
• Thread Safe - Lock-free graph execution where possible

Building

# Clone repository
git clone https://github.com/yourusername/rustVX.git
cd rustVX

# Build with cargo
cargo build --release --all

# Run tests
cargo test --all

Usage

C API

#include <VX/vx.h>

vx_context context = vxCreateContext();
vx_graph graph = vxCreateGraph(context);

// Create nodes...
vxVerifyGraph(graph);
vxProcessGraph(graph);

vxReleaseGraph(&graph);
vxReleaseContext(&context);

Rust API

use rustVX::prelude::*;

let context = Context::new()?;
let mut graph = context.create_graph()?;

// Create nodes...
graph.verify()?;
graph.execute()?;

Conformance

This implementation passes the Khronos OpenVX Conformance Test Suite for:

• Base Feature Set
• Vision Conformance Feature Set
