A page of a document is a set of small components which are grouped by a human reader into higher level components, such as lines and text blocs. Document image analysis is aimed at detecting these components in document images. We propose the encoding of local information by considering the properties that determine perceptual grouping. Each connected component is labelled according to the loc...

* [email protected] Abstract The purpose of this paper is to name and discuss some of the most basic issues in today’s optical microlithography, promoting industry consensus and, specifically, definition of the industry standard Patterning Design Rules (PDR), that is, Design Rules for “patterns as built”. Dimensional metrology for seamless PDR compliance is discussed, highlighting th...

This paper describes a new approach for organizing image data. Perceptual organization in biological vision is the process of pre-attentively grouping and structuring perceptual information into shapes and forms. In computer vision, processes like these are required in order to transform pixels into structural forms that can be used in higher-level interpretation. Pyramidal structures have been...

The process by which the human visual system parses an image into contours, surfaces, and objects--perceptual grouping--has proven difficult to capture in a rigorous and general theory. A natural candidate for such a theory is Bayesian probability theory, which provides optimal interpretations of data under conditions of uncertainty. But the fit of Bayesian theory to human grouping judgments ha...
