Hi Boris! It's Brad from Dropbox :)
Responding to the parent comment, in terms of running time, the primary bottleneck is the RCNN localization portion; that takes about a minute and a half on my laptop to process a single image. In the Future Work section of the blog post I talk about collapsing the entire detection and localization pipeline into a single deconvolution network that directly takes in raw images and outputs image masks. The hope is that this runs much faster at inference time.
