Extracting Straight Lines
TL;DR: The algorithm appears to be more effective than previous techniques for two key reasons: 1) the gradient orientation is used as the initial organizing criterion prior to the extraction of straight lines, and 2) the global context of the intensity variations associated with a straight line is determined prior to any local decisions about participating edge elements.
Journal ArticleDOI
The Schema System
TL;DR: This paper presents a meta-modelling framework that automates the very labor-intensive and therefore time-heavy and expensive process of manually cataloging and cataloging individual objects in a scene.
Journal ArticleDOI
The Image Understanding Architecture
TL;DR: This paper provides an overview of the Image Understanding Architecture (IUA), a massively parallel, multilevel system for supporting real-time image understanding applications and research in knowledge-based computer vision.
Journal ArticleDOI
Scene Text Recognition Using Similarity and a Lexicon with Sparse Belief Propagation
TL;DR: A probabilistic model for scene text recognition is introduced that integrates similarity, language properties, and lexical decision and is fusing information sources in one model to eliminate unrecoverable errors that result from sequential processing, improving accuracy.
Journal ArticleDOI
Segmenting Images Using Localized Histograms and Region Merging
TL;DR: A working system for segmenting images of complex scenes is presented that integrates techniques that have evolved out of many years of research in low-level image segmentation at the University of Massachusetts and elsewhere.
