nanobbox is a package that calculates Intersection over Union(IoU). This is based on cython_bbox and reimplemented using nanobind. Speedup is achieved by using nanobind and openmp.
pip install nanobbox
or
git clone https://github.com/neka-nat/nanobbox.git
cd nanobbox

np.ascontiguousarray(dt, dtype=np.float32),
np.ascontiguousarray(gt, dtype=np.float32)
)| time | |
|---|---|
| cython_bbox | 0.87s |
| nanobbox | 0.77s |
| nanobbox(omp) | 0.22s |
