We present means of interactive definition of anatomic objects in medical images via a desl.Tiption of the image in terms of visually sensible regions. The description is produced by computing srrucrures capturing image geometry and following them through the image simplification of Gaussian blurring. In particular, we suggest that the s1l'llcture made from intensity "ridge" and "course" curves...

Abstract Frege argues that number is so unlike the things we accept as properties of external objects it cannot be such a property. In particular, (1) arbitrary in way qualities are not, and (2) not predicated its subjects are. Most Aristotle scholars suppose either has refuted Aristotle's theory or avoids Frege's objections by making numbers objects. This led some to conclude accounts arithmet...

We consider the problem of computing minimum geometric hitting sets in which, given a set of geometric objects and a set of points, the goal is to compute the smallest subset of points that hit all geometric objects. The problem is known to be strongly NP-hard even for simple geometric objects like unit disks in the plane. Therefore, unless P=NP, it is not possible to get Fully Polynomial Time ...

Situation Awareness involves the comprehension of the state of a collection of objects in an evolving environment. This not only includes an understanding of the objects’ characteristics but also an awareness of the significant relations that hold among the objects at any point in time. Systems for establishing situation awareness require a knowledge representation for these objects and relatio...

In theorizing about perception, philosophers have often multiplied qualities. To perceptible qualities of external objects, like colors and shapes (‘sensible’ qualities), have been added qualities of experiences (‘sensory’ qualities) or of sense-data (‘sensational’ qualities). Start with sensory qualities. The phrase ‘sensory quality’ is not much in use these days, having lost out to ‘phenomena...
