autothresholdr provides algorithms for automatically finding appropriate thresholds for numerical data, with special functions for thresholding images. It does this by porting ImageJ “Auto Threshold” plugin functionality to R.
The github repo of autothresholdr is at https://github.com/rorynolan/autothresholdr.
