QOI Benchmark

Cross-language benchmark for QOI implementations

Implementations

• qoi
• qoixx
• qoi-rust
• rapid-qoi
• qoi-fu
  • qoi-fu_cxx : implementation transpiled to C++
• qoipp

Usage

• With Singularity

  • host$ curl https://qoiformat.org/benchmark/qoi_benchmark_suite.tar | tar x
    host$ ./cxx_environment/build.bash
    host$ ./cxx_environment/bash
    singularity$ make
    singularity$ benchmark/bin/qoibench 20 images

• On Host
  • Prerequisites:
    • gcc for qoi
    • g++ supporting -std=c++2a for qoixx and qoi-fu_cxx
    • cargo and Rust toolchains for qoi-rust and rapid-qoi
    • make

  • $ make
    $ benchmark/bin/qoibench 20 /path/to/image/directory

How to add my implementation?

You can add your own QOI implementation in this project. If you want it, you need to implement C interface as same as original implementaion. More concretely, you should implement below functions:

void* your_own_qoi_encode(const void* data, const qoi_desc* desc, int* out_len);
void* your_own_qoi_decode(const void* data, int size, qoi_desc* desc, int channels); // it's OK that the last argument doesn't work. In this project channels is same as desc.channels.

void your_own_qoi_free(void* ptr); // provide appropriate deallocation method corresponding to allocation method you used in encode/decode

Then, create static library (libyour_own_qoi.a) with your implementations. Finally, add new entry about your implementation in benchmark/include/implementations.hpp.

The example is here.
