The 2015 and 2014 Synchronization of Multi-User Event Media datasets.The datasets, ground-truth time-synchronization results and corresponding evaluation script that were created and used in the 2015 and 2014 editions of the Synchronization of Multi-User Event Media (SEM) task of the MediaEval benchmarking activity are available for download. The datasets comprise multiple galleries of images, videos and audio recordings per event, for several real-life events attended by multiple individuals.
The dataset consists of 2450 digital images (1219 undistorted, 631 naturally-blurred and 600 artificially-blurred images), divided to a training set and an evaluation set. This dataset is used for the evaluation of image quality assessment methods (specifically, methods detecting blurring in images). An important feature of it is that it contains naturally-blurred images as well, rather that only artificially-blurred ones.
