OSS, security and Funding: libjpeg-turbo

libjpeg-turbo is a widely used library that decodes JPEG images on various digital devices. It is also utilized in computer vision model training to decode images. A benchmark of Python libraries that decode JPEG images found that top libraries rely on libjpeg-turbo due to its heavy optimization. A pull request was made to improve the library's performance by 3%, but it was refused due to the potential disruption not being justified by the small improvement. The library's optimization is a key factor in its widespread use. The refusal of the pull request highlights the challenges of contributing to heavily relied upon open-source projects.
