A Context-Dependent Kernel for Logo RecognitionWe contributed 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 features (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 introduced a detection/recognition procedure and we studied its theoretical consistency. We show the validity of our method through extensive experiments on the novel 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.

* Part of this work was conducted while me and Giuseppe Serra were visiting scholars at Telecom ParisTech (in spring 2010) under the supervision of Hichem Sahbi.
