Frequently Asked Questions

What is a colony counter?

A colony counter is a tool used in microbiology to count bacterial colonies growing on a culture medium. Our online colony counter uses advanced image processing algorithms to automatically detect and count colonies from images of petri dishes, saving researchers time and improving accuracy compared to manual counting methods.

How accurate is the colony detection?

The accuracy of our colony counter depends on image quality and colony characteristics. For clear, well-separated colonies with good contrast against the background, the detection accuracy can exceed 95%. You can improve accuracy by adjusting the sensitivity settings and ensuring proper lighting when capturing images. The tool works best with uniform backgrounds and distinct colony boundaries.

What image formats are supported?

Our colony counter supports common image formats including JPG, JPEG, PNG, and GIF. For best results, we recommend using high-resolution images with good lighting and contrast. Images should be taken directly above the petri dish to minimize distortion. The maximum file size is 10MB to ensure fast processing.

Can I adjust the detection parameters?

Yes, our tool provides adjustable parameters to optimize detection for different types of colonies. You can adjust the sensitivity level to control detection strictness, set minimum and maximum colony sizes to filter out noise or large clusters, and toggle the detection overlay to visualize which colonies were identified. These settings allow you to customize the analysis for specific experimental conditions.

How can I improve detection accuracy?

To improve detection accuracy: 1) Use images with good lighting and contrast, 2) Ensure colonies are well-separated and not overlapping, 3) Take photos directly above the petri dish to avoid perspective distortion, 4) Use a uniform background if possible, 5) Adjust the sensitivity settings based on your specific image characteristics, and 6) Set appropriate minimum and maximum colony size filters to exclude noise and large clusters.

Is my data private and secure?

Yes, we take data privacy seriously. All image processing is performed directly in your browser using JavaScript, and your images are never uploaded to our servers. This means your research data remains completely private and secure on your own device. No images or analysis results are stored or transmitted externally.

Can I export the results?

Yes, you can export your colony counting results in two ways: 1) Copy the text results to your clipboard for pasting into reports or spreadsheets, or 2) Download the processed image with colony overlays for visual documentation. The text results include colony count, average size, and detailed information about each detected colony including position and size measurements.
