Getting Started

To count the dots on a petri dish, an uploaded image will be resized to 1000px in width maintaining aspect ratio relative to height. Two results will be shown. Highlighted dots that have been run through a Gaussian filter, Canny edge detector with threshold of low=50 high=150, and the original image.

We can later add input for threshold and canny parameters to fine tune the conditions of the image to set for your needs.

Count Your Colonies

Upload an image with the petri dish borders close to the edge of the width of the image. The fewer irregularities in the background, the better the result.

Below are random images of petri dishes with colonies found on the internet. Accuracy varies with the quality of the image and the environmental conditions.
