13. M. Marszalek, C. Schmid, J. Zhang, S. Lazebnik: Bag-of-features image representation: state-of-the-art and beyond
We present our bag-of-features based image classification framework and discuss the selection of different building blocks [1]. We then examine the influence of background clutter on the bag-of-features representation and present a spatial extension to this representation that reduces its sensitivity to background clutter [2]. Finally, we will show some of our recent work which extends and generalizes the framework to perform simultaneous object localization and segmentation.
