You could avoid the blocking queue if you dispatch the background thread's
runnable at the end of the UI thread's block.
I see you send a success callback as soon as the image is captured, but
before it is saved. This would improve throughput, but it might be even
more useful if you set the keepCallback flag on it and then send another
success response once you have the filename / comparison results. It's the
filename that the app is probably interested in.
