Yeast SporeCount . The deep learning algorithm for yeast is designed to count yeast cells even up to high concentrations. In image on the right you see an near to perfect count of yeast. In any case, this is much better than manual ...This counting method is very popular among previously published spore work, and thus, it was chosen in order to make current study comparable with others (e.g. Skjøth et al. 2015). Then spore counts were multiplied by a correction factor resulting in an estimation of number of spores per cubic metre of air (s m −3) after Lacey and West .Why you should count your chickens (and kookaburras, lorikeets or other backyard birds) by Fran Molloy, Macquarie University.
