Benchmarking PySceneDetect

This repository benchmarks the performance of PySceneDetect in terms of both latency and accuracy. We evaluate it using the standard dataset for video shot detection: BBC.

Dataset Download

BBC

# annotation
wget -O BBC/fixed.zip https://zenodo.org/records/14873790/files/fixed.zip
unzip BBC/fixed.zip -d BBC
rm -rf BBC/fixed.zip

# videos
wget -O BBC/videos.zip https://zenodo.org/records/14873790/files/videos.zip

Evaluation

To evaluate PySceneDetect on a dataset, run the following command:

python benchmark.py -d <dataset_name> --detector <detector_name>

For example, to evaluate ContentDetector on the BBC dataset:

python evaluate.py -d BBC --detector detect-content

Result

The performance is computed as recall, precision, f1, and elapsed time. The following results indicate that ContentDetector achieves the highest performance on the BBC dataset.

Detector Recall Precision F1 Elapsed time (second)
AdaptiveDetector 87.52 97.21 92.11 27.84
ContentDetector 85.23 89.53 87.33 26.46
HashDetector 92.96 76.27 83.79 16.26
HistogramDetector 90.55 72.76 80.68 16.13
ThresholdDetector 0.00 0.00 0.00 18.95
KoalaDetector 86.83 78.38 82.39 97.75
