Description

Environment:
OS X 10.8 + Xcode4.5.1 + iPhone 4(with iOS 6.0.1)

Actual result:
I wrote a demo step by step from http://docs.opencv.org/trunk/doc/tutorials/ios/video_processing/video_processing.html,
after I finished the program, I run it on my iPhone4 (iOS6.0.1).
I found it runned not so fluently when processing the video.
I searched information from internet, some people believes it is because that opencv does not optimise on arm architecture.

Expect result:
OpenCV could process the video fluently.

first of all, iphone 4 is a quite slow device, it's already >2 generations behind the modern devices (A4->A5->A5X->A6->A6X). secondly, low performance is not a bug, it's feature request.
