Analyze time spent by customers at cashier counters and cars in traffic by monitoring predefined zones in video frames.

Here’s a revised version of the instructions focused solely on video processing, with outputs directed to a specific output folder, and made more readable:

Video Time Analysis

👋 Introduction

This project demonstrates the use of computer vision techniques to analyze wait times and monitor the duration that objects or individuals spend in predefined zones within video frames. It's ideal for applications like retail analytics or traffic management.

Sample Outputs

Analysis For Customer Waiting Time

Analysis For Cars Waiting Time

🛠 Video Processing Scripts

download_from_youtube

This script downloads videos from YouTube.

• --url: The full URL of the YouTube video to download.
• --output_path: Directory to save the downloaded video (default: output folder).
• --file_name: Name of the saved video file.

Example Usage:

python scripts/download_from_youtube.py \
--url "https://www.youtube.com/watch?v=-8zyEwAa50Q" \
--output_path "output/checkout" \
--file_name "video.mp4"

python scripts/download_from_youtube.py \
--url "https://www.youtube.com/watch?v=MNn9qKG2UFI" \
--output_path "output/traffic" \
--file_name "video.mp4"

draw_zones

Use this script to design custom zones on your video. The zones are saved as a JSON file.

• --source_path: Path to the video file.
• --zone_configuration_path: Path to save the polygon annotations (as a JSON file).

Key Controls:

• Enter: Finish drawing the current polygon.
• Escape: Cancel drawing the current polygon.
• Q: Quit the drawing window.
• S: Save zone configuration to a JSON file.

Example Usage:

python scripts/draw_zones.py \
--source_path "output/checkout/video.mp4" \
--zone_configuration_path "output/checkout/config.json"

python scripts/draw_zones.py \
--source_path "output/traffic/video.mp4" \
--zone_configuration_path "output/traffic/config.json"

inference_file_example

Run object detection on a video file using the Roboflow Inference model.

• --zone_configuration_path: Path to the zone configuration JSON file.
• --source_video_path: Path to the video file.
• --model_id: Roboflow model ID.
• --classes: List of class IDs to track (optional).
• --confidence_threshold: Confidence level for detections (default: 0.3).
• --iou_threshold: IOU threshold for non-max suppression (default: 0.7).

Example Usage:

python inference_file_example.py \
--zone_configuration_path "output/checkout/config.json" \
--source_video_path "output/checkout/video.mp4" \
--model_id "yolov8x-640" \
--classes 0 \
--confidence_threshold 0.3 \
--iou_threshold 0.7

python inference_file_example.py \
--zone_configuration_path "output/traffic/config.json" \
--source_video_path "output/traffic/video.mp4" \
--model_id "yolov8x-640" \
--classes 2 5 6 7 \
--confidence_threshold 0.3 \
--iou_threshold 0.7
