Area of Science:

* Physics
* Engineering

Background:

* High-speed particle tracking generates massive data volumes, necessitating compromises in resolution and acquisition duration.
* Particle tracking images often feature sparse bright pixels against dark backgrounds, indicating potential for efficient compression.

Purpose of the Study:

* To develop and describe a system for real-time compression of high-speed digital video data.
* To overcome limitations in data acquisition duration imposed by high data rates in particle tracking experiments.

Main Methods:

* A digital circuit was implemented between the camera and frame grabber for real-time data processing.
* The system compresses video by comparing input pixels to a threshold, outputting pixel brightness and position data.
* Utilizes a thresholding method to identify and transmit only relevant pixel information.

Main Results:

* Achieved compression ratios ranging from 100 to 1000 dynamically based on pixel data.
* Reduced data rates allowed direct writing to hard disk storage.
* Extended continuous data acquisition from 6.5 seconds to up to a week using a 600 GB hard drive.

Conclusions:

* The real-time compression system effectively mitigates data rate bottlenecks in high-speed particle tracking.
* Enables significantly longer experimental data acquisition at full resolution.
* Offers a practical solution for researchers dealing with large datasets in particle imaging.
