Problem: while apps have face detection available from iOS and Android for use in lead image positioning/cropping, mobile web doesn't have it, and even for apps detection is quite slow, resulting in battery drain and UX-problematic slowdown, especially on low-end Android devices.
With Dmitry's help, I discovered Android's face detection library sources ([1], separated out to a standalone library at [2]). This means that we can build a face detection service and supply its results to all users, be that apps, web or third parties.
Thoughts?
