Dataset Description
The dataset consists of 8658 frames extracted from video sequences
for evaluation of image search on mobile scenario.
The sequences show a table containing several objects, including postcards,
little boxes, papers, flowers, glasses, bottles, business cards and magazines.
Three different devices have been used: GoPro, Nexus 7 and iPhone.
Videos have been recorded in different times of the day, with natural and
artificial light generating different shadow shapes and reflections.
Videos are also subject to blurring and different zooms of the target object.
The objects have been setup in order to create occlusions or transparency
effects. Moreover, several features on different queries could match the same
features on a given database image, producing false positive matches. The dataset can be downloaded from this page, see details below. The material
given includes:
Download and Statistics

Evaluation Protocol
In order to assess the presence of a query object in a frame, for each frame and
for each object a score can be computed by means of a custom matching algorithm.
By thresholding the score values, a binary map can be built and compared to
the ground-truth. The result is the computation of true positive ratio (TPR)
and false positive ratio (FPR) metrics.
