OpenCV Performance Measurements on Mobile Devices

Marco A. Hudelist, Claudiu Cobârzan and Klaus Schoeffmann - ICMR 2014

Mobile devices like smartphones and tablets are becoming increasingly capable in terms of processing power. Although they are already used in computer vision, no comparable measurement experiments of the popular OpenCV framework have been made yet. We try to ll this gap by evaluating the performance of a set of typical OpenCV operations, on mobile devices like the iPad Air and iPhone 5S. We compare those results with the performance of a consumer
grade laptop PC (MacBook Pro). Our tests span from simple image manipulation methods to keypoint detection and descriptor extraction as well as descriptor matching. Results show that the top performing device can match the performance of the PC up to 80 percent in specific operations.
