Using colour pattern edge contrast statistics to predict detection speed and success in triggerfish (Rhinecanthus aculeatus)

Summary: The speed with which triggerfish detect patterned stimuli cannot be explained by a single image statistic. The relationship between pattern statistics and animal behaviour is complex, and is likely to be distance dependent.

Pretty fucking bold of these scientists to scrape one of my copyrighted photographs off the internet and then re-release it uncredited under a Creative Commons license because they used it for training data for an algorithm.

As part of a research project led by Maël Doré (@Eonymus) on mimicry in tropical butterflies, we have developed a survey to quantify our perception of butterfly color patterns. ⌛ < 10 min

Your participation would be very helpful.The more data we have, the better. Thank you so much!

Mastodon has a very big surge of new users right now. There's no way to tell if it will be sustained, but at this early point it looks similar to Nov 18 when Musk pulled the employee purge.

It is very challenging for system administration to accommodate so many new users. If your server starts to struggle, it is not broken and will get sorted out.

We're all in this together. It's our social network. Be patient. What we are building is amazing.

“The disproportionate scientific productivity of elite researchers can be largely explained by their substantial labor advantage rather than inherent differences in talent.” #AcademicMastodon #ScienceMastodon https://www.science.org/doi/10.1126/sciadv.abq7056
I did my PhD at the University of Queensland (AUS) in 2020, specialising in devel. visual modelling tools to study defensive colouration in nudibranchs & investigating colour, pattern and luminance contrast perception in triggerfish. After a brief postdoc in my old lab (automating workflows and analyzing mountains of data), I have just relocated to the University of Bristol thanks to an SNF mobility fellowship. Here, I investigate polarisation vision in marine inverts and expand methodology.
