Common functionality for object detection
This repository hosts functions that are commonly used across object detection projects. The functionality here includes:
- Box overlap computation (IoU)
- Precision and recall calculations
- Computing targets for training a detector given a set of ground-truth objects
- Non-maximum suppression
- Coordinate transform utilities
- Focal loss in PyTorch
All the functions here are well-tested to ensure proper functionality of these utilities. This repository is meant to ensure that modifications and improvements that are implemented as part of one program migrate to other programs when appropriate.
To use detection-utils you will need numpy, numba, and optionally pytorch. We recommend either fetching numpy
from Anaconda or ensuring you can link against MKL yourself for
performance. You can install numba via pip and PyTorch should be installed
according to your needs. For example:
$ conda install numpy
$ pip install numba torch torchvisiondetection-utils is availabe on PyPI: install via
$ pip install detection-utilsClone this repository and install:
$ git clone https://github.com/davidmascharka/detection-utils.git && cd detection-utils
$ pip install .To verify installation, ensure that pytest and
hypothesis are installed, then run
pytest from the detection-utils base directory.
If you're interested in contributing to this library, a good place to start is by browsing for open issues to see if there are desired features waiting for implementation. Please see the contributors file before you submit a pull request.
