DBRIS at ImageCLEF 2012 Photo Annotation Task
Magdalena Rischka, Stefan Conrad · 2013
Abstract. For our participation in the ImageCLEF 2012 Photo Annotation Task we develope an image annotation system and test several combinations of SIFT-based descriptors with bow-based image representations. Our focus is on the comparison of two image representation types which include spatial layout: the spatial pyramids and the visual phrases. The experiments on the training and test set show that image representations based on visual phrases significantly outperform spatial pyramids.
