PlaqSeg

Instantly analyse bacteriophage plaques with ML-powered detection. Accurate counting, detailed metrics, and CSV export for research labs. Fast, precise, and offline.

Transform your bacteriophage research with PlaqSeg - the intelligent plaque detection and counting app designed for microbiology labs and phage researchers.

Key Features:

Automated Plaque Detection • Advanced computer vision algorithms instantly identify and segment plaques • Works directly from your phone camera or photo library • Results in seconds, not minutes

ML Classification • Trained CNN model filters false positives with 93%+ accuracy • Adjustable confidence thresholds for precision control • Continuously improving detection quality

Detailed Analytics • Accurate plaque counting and statistics • Size distribution analysis (area measurements) • Circularity scoring for morphology studies • PFU calculator for titer calculations

Export & Share • Generate comprehensive CSV reports • Export annotated images with overlay visualizations • Complete analysis history tracking • Easy data sharing for publications

Professional Controls • Customizable detection parameters • Manual editing: add or exclude plaques • Fine-tune filters for your specific assays • Works offline - no internet required

Tips for Best Results: • Photograph petri dishes directly (not screens) • Use dark, non-reflective backgrounds • Ensure good, even lighting • Hold camera parallel to dish surface

Perfect for: • Phage therapy research • Bacteriophage quantification • Microbiology labs and courses • Quality control in phage production • Environmental phage studies
