ezTrack

ezTrack performs video-based tracking and quantification of animal behavior to generate frame-by-frame behavioral measures for alignment with physiological recordings.

Key Features:

• Interactive Python-based analysis: Uses interactive Python scripts with interactive plots and visualizations for parameter selection and result inspection.
• Positional Analysis Module: Tracks the location and motion of an individual animal for a broad spectrum of behavioral tasks.
• Freezing Behavior Module: Detects and quantifies freezing behavior from video recordings.
• Batch Processing: Processes multiple video files in batch to enable rapid analysis of large datasets.
• Frame-by-Frame Output: Produces frame-by-frame output to facilitate precise temporal alignment with biological recording data.
• Customization Options: Provides video cropping, time-segment selection, and region-of-interest (ROI) definition to tailor analyses and exclude interference such as fiberoptic/electrophysiology cables.

Scientific Applications:

• Positional tracking in behavioral assays: Quantifies animal location and motion across a wide range of behavioral experiments.
• Freezing behavior measurement: Quantifies immobility events for studies requiring freezing analysis.
• Integration with physiological recordings: Aligns behavioral measures with electrophysiology and fiberoptic physiological recordings via frame-by-frame outputs.

Methodology:

Interactive Python scripts with interactive plots and visualizations; separate modules for positional tracking and freezing behavior; batch processing of multiple video files; frame-by-frame output generation; options for video cropping, time-specific analysis, and ROI definition.
