How Can Multithreaded Python Speed Up Data Augmentation?

TL;DR

Multithreaded Python programming can significantly speed up data augmentation for deep learning projects, turning a dataset of 8 images into 80 in just 35 seconds, compared to 2 minutes and 26 seconds with single-threading. This approach is essential for researchers working with limited datasets, enhancing the training data effectively.
