Context-Dependent Logo Matching and Recognition

Our paper “Context-Dependent Logo Matching and Recognition” by H. Sahbi, L. Ballan, G. Serra, and A. Del Bimbo has been accepted for publication by the IEEE Transactions on Image Processing.

We contribute through this work to the design of a novel variational framework able to match and recognize multiple instances of multiple reference logos in image archives.
Reference logos as well as test images, are seen as constellations of local feature (interest points, regions, etc.) and matched by minimizing an energy function mixing (i) a fidelity term that measures the quality of feature matching (ii) a neighborhood criterion which captures feature co-occurrence/geometry and (iii) a regularization term that controls the smoothness of the matching solution. We also introduce a detection/recognition procedure and we study its theoretical consistency. Finally, we show the validity of our method through extensive experiments on the challenging MICC-Logos dataset overtaking, by 20%, baseline as well as state-of-the-art matching/recognition procedures. We present also results on another public dataset, the FlickrLogos-27 image collection, to demonstrate the generality of our method.
