Automatic colony counting in a Petri Dish

 Reactiv’IP developed a dedicated python macro based on the IPSDK library to count and measure colonies present in a Petri Dish.

Petri Dish with the detected colonies marked with different colours.

This system allows to quickly count the number colonies present in a Petri Dish (in this case 255).

Thanks to this segmentation we also obtain measures calculated for each object detected.


More complex example

With IPSDK, it’s also possible to adapt the script to analyse more complex image. For example, on the right, we can see a Petri Dish, with a red marker with a lot of very small colonies. In this case, the detection is very good compared to a human counting.
