To have a robust and informative image content representation for image categorization, we often need to extract as many as possible visual features at various locations, scales a...
Abstract. The scale invariant property of an ensemble of natural images is examined which motivates a new early visual representation termed the higher order pyramid. The represent...
—A method for locating mathematical expressions in document images without the use of optical character recognition is presented. An index of document regions is produced from re...
Abstract. A model of human appearance is presented for efficient pose estimation from real-world images. In common with related approaches, a high-level model defines a space of co...

Shape symmetry is an important cue for image understanding. In the absence of more detailed prior shape information, segmentation can be significantly facilitated by symmetry. How...
