How to use CLAMS apps

App Directory

swt-detection

Detects scenes with text, like slates, chyrons and credits.

whisper-wrapper

A CLAMS wrapper for Whisper-based ASR software originally developed by OpenAI.

distil-whisper-wrapper

The wrapper of Distil-Whisper, avaliable models: distil-large-v3, distil-large-v2, distil-medium.en, distil-small.en. The default model is distil-small.en.

tfidf-keywordextractor

extract keywords of a text document according to TF-IDF values. IDF values and all features come from related pickle files in the current directory.App can either take a simple text document or take a MMIF file generated from the text slicer app.

spacy-wrapper

Apply spaCy NLP to all text documents in a MMIF file.

text-slicer

Slice text snippets from a provided text document given time frames

simple-timepoints-stitcher

Stitches a sequence of TimePoint annotations into a sequence of TimeFrame annotations, performing simple smoothing of short peaks of positive labels.

east-textdetection

OpenCV-based text localization app that used EAST text detection model. Please visit the source code repository for full documentation.

llava-captioner

Applies llava to video frames.

inaspeechsegmenter-wrapper

inaSpeechSegmenter is a CNN-based audio segmentation toolkit. The original software can be found at https://github.com/ina-foss/inaSpeechSegmenter .

doctr-wrapper

CLAMS app wraps the docTR, End-to-End OCR model, available at https://pypi.org/project/python-doctr . The model is capable of detecting text regions in the input image and recognizing text in the regions. The text-localized regions are organized hierarchically by the model into “pages” > “blocks” > “lines” > “words”, and this CLAMS app translates them into TextDocument, Paragraphs, Sentence, and Token annotations to represent recognized text contents, then aligns them to BoundingBox annotations that represent the detected geometries. This hierarchical structure is also represented in the TextDocument annotation output as two newlines (\n\n) between “paragraphs”, one newline (\n) between the “lines”, and one space (“ “) between the “words”. For the text recognition, the model is internally configured to use the “parseq” recognition model, and only works with English text at the moment.

pyscenedetect-wrapper

easyocr-wrapper

Using EasyOCR to extract text from timeframes

dbpedia-spotlight-wrapper

Apply named entity linking to all text documents in a MMIF file.

slatedetection

This tool detects slates.

fewshotclassifier

This tool uses a vision model to classify video segments. Currenly supports “chyron” frame type.

barsdetection

This tool detects SMPTE color bars.

parseqocr-wrapper

This tool applies Parseq OCR to a video or image and generates text boxes and OCR results.

tesseractocr-wrapper

This tool applies Tesseract OCR to a video or image and generates text boxes and OCR results.

chyron-detection

This tool detects chyrons, generates time segments.

gentle-forced-aligner-wrapper

This CLAMS app aligns transcript and audio track using Gentle. Gentle is a robust yet lenient forced aligner built on Kaldi.This app only works when Gentle is already installed locally.Unfortunately, Gentle is not distributed as a Python package distribution.To get Gentle installation instruction, see https://lowerquality.com/gentle/ Make sure install Gentle from the git commit specified in analyzer_version in this metadata.

tonedetection

Detects spans of monotonic audio within an audio file

brandeis-acs-wrapper

Brandeis Acoustic Classification & Segmentation (ACS) is a audio segmentation tool developed at Brandeis Lab for Linguistics and Computation. The original software can be found at https://github.com/brandeis-llc/acoustic-classification-segmentation .

aapb-pua-kaldi-wrapper

A CLAMS wrapper for Kaldi-based ASR software originally developed by PopUpArchive and hipstas, and later updated by Kyeongmin Rim at Brandeis University. Wrapped software can be found at https://github.com/brandeis-llc/aapb-pua-kaldi-docker .
