This paper describes a new framework for processing images by example, called &#8220;image analogies.&#8221; The framework involves two stages: a <i>design phase</i>, in which a pair of images, with one image purported to be a &#8220;filtered&#8221; version of the other, is presented as &#8220;training data&#8221;; and an <i>application phase</i>, in which(More)
Grid-based page designs are ubiquitous in commercially printed publications, such as newspapers and magazines. Yet, to date, no one has invented a good way to easily and automatically adapt such designs to arbitrarily-sized electronic displays. The difficulty of generalizing grid-based designs explains the generally inferior nature of on-screen layouts when(More)
Cheap and versatile cameras make it possible to easily and quickly capture a wide variety of documents. However, low resolution cameras present a challenge to OCR because it is virtually impossible to do character segmentation independently from recognition. In this paper we solve these problems simultaneously by applying methods borrowed from cursive(More)
We present a new representation for time-varying image data that allows for varying—and arbitrarily high—spatial and temporal resolutions in different parts of a video sequence. The representation, called multiresolution video, is based on a sparse, hierarchical encoding of the video data. We describe a number of operations for creating, viewing, and(More)
We present a system for designing and displaying grid-based document designs that adapt to many different viewing conditions and content selections. Our system can display traditional, static documents, or it can assemble dynamic documents "on the fly" from many disparate sources via the Internet. Our adaptive layouts for aggregated documents are inspired(More)
This thesis presents an image-based rendering framework for creating non-photorealistic applications that achieve frame-to-frame coherence, interactivity, stylistic flexibility, and visual detail. To date, most researchers pursuing dynamic nonphotorealism have focused on rendering specific visual styles, with methods for achieving frame-to-frame coherence(More)
