imagezero

Pure Rust implementation of the imagezero (losless image compression algorithm) used i.e. in robotics.

Documentation

Read the detailed documentation here

imagezero-rs

Pure Rust implementation with NEON64 optimizations. Includes a commandline example.

imagezero-sys

Rust wrapper for the C++ implementation.

testing

Benchmark for checking the speed of the different implmentations.

cargo test
cargo bench

testing/images

Here the test images should reside.

Build

For building and running the tests (also does a check against the cpp implementation)

cargo test
cargo bench

If you would like to build/test the commandline utils (you have to checkout the cpp submodule)

cd imagezero-sys/imagezero-cpp
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

cd imagezero-sys
cargo build --release

cd testing/image
./check.sh

ToDo

• imagezero algorithm in Rust
• create benchmarks
• ARM64 optimizations
• VHDL compression
• Stereo Cam for ROS2

Done

• test imagezero-sys against cpp
• create imagezero-sys with Rust commandline program
• reserve name on crates.io
