pliers: a python package for automated feature extraction
Pliers is a Python package for automated extraction of features from multimodal stimuli. It provides a unified, standardized interface to dozens of different feature extraction tools and services--including many state-of-the-art deep learning-based models and content analysis APIs. It's designed to let you rapidly and flexibly extract all kinds of useful information from videos, images, audio, and text.
You might benefit from pliers if you need to accomplish any of the following tasks (and many others!):
- Identify objects or faces in a series of images
- Transcribe the speech in an audio or video file
- Apply sentiment analysis to text
- Extract musical features from an audio clip
- Apply a part-of-speech tagger to a block of text
Each of the above tasks can typically be accomplished in 2 - 3 lines of code with pliers. Combining them all--and returning a single, standardized DataFrame--might take a bit more work. Say maybe 5 or 6 lines.
In a nutshell, pliers provides a high-level, unified interface to a large number of feature extraction tools spanning a wide range of modalities.
