-We are interested in identifying the material category, +We describe a framework for improving the quality of personal photos by using a person’s favorite photographs as examples. We observe that the majority of a person’s photographs include the faces of a photographer’s family and friends and often the errors in these photographs are the most disconcerting. We focus on correcting these types of images and use common faces across images to automatically perform both global and face-specific corrections. Our system achieves this by using face detection to align faces between “good” and “bad” photos such that properties of the good examples can be used to correct a bad photo. These “personal” photos provide strong guidance for a number of operations and, as a result, enable a number of high-quality image processing operations. We illustrate the power and generality of our approach by presenting a novel deblurring algorithm, and we show corrections that perform sharpening, superresolution, in-painting of over- and underexposured regions, and white-balancing.
-e.g. glass, metal, fabric, plastic or wood, from a single image +
-of a surface. Unlike other visual recognition tasks in +
-computer vision, it is difficult to find good, reliable features +
-that can tell material categories apart. Our strategy is to +
-use a rich set of low and mid-level features that capture various +
-aspects of material appearance. We propose an augmented +
-Latent Dirichlet Allocation (aLDA) model to combine +
-these features under a Bayesian generative framework +
-and learn an optimal combination of features. Experimental +
-results show that our system performs material recognition +
-reasonably well on a challenging material database, +
-outperforming state-of-the-art material/texture recognition +
