A study in descriptive representation of pictorial data

Pattern Recognition, 1972
Although much effort has been expended on automatic scene description, especially in the various robot and “hand-eye” projects, these efforts have usually been directed toward description for immediate use, i.e. description of a scene for the purpose of stacking blocks using a manipulator arm, or for allowing a robot to move through an environment ...

Representation and reasoning with attributive descriptions

1990
This paper surveys terminological representation languages and feature-based unification grammars pointing out the similarities and differences between these two families of attributive description formalisms. Emphasis is given to the logical foundations of these formalisms.

Conic Representations for Shape Description

IEEE Computer Graphics and Applications, 1987
The question of what is the "best" form of geometry for use in CAD systems and for data exchange between systems has often been argued with much intuition but few facts. I will present here some numerical stability results for several formulations of conic curves with the conclusion that the point/vector/scalar representation performs best.

Representation and Description of Forms

2020
The chapter defines the modalities of representation and description of the shape of homogeneous regions obtained from the segmentation process. A region can be represented by the pixels of its boundary (external representation) or represented as an aggregation of its pixels (internal representation).

Granule description in knowledge granularity and representation

Knowledge-Based Systems, 2020
Abstract Granule description is an important problem in knowledge granularity and representation. In the theoretical study of granule description, two basic sub-problems need to be solved: (1) check whether a target granule is definable, and try to offer an exact description for the target granule if definable; (2) an appropriate approximate ...

Hybrid Representation of Spatial Descriptions

2019
Recipients of spatial descriptions have to draw on conceptual knowledge to arrive at integrated semantic interpretations. Conceptual knowledge helps in choosing the adequate interpretation. The computational requirements of an integrated interpretation of spatial descriptions are better met by analog representations than by propositional ...

Shape representation and description

1993
The last chapter was devoted to image segmentation methods which showed how to construct homogeneous regions of images and/or their boundaries. Recognition of image regions is one of the most important steps on the way to understanding image data, and requires an exact region description in a form suitable for a classifier (Chapter 7). This description

Descriptive Representation Revisited

2020
Descriptive representation—understood as a concern that the gender and ethnic composition of elected assemblies should roughly correspond to the gender and ethnic composition of their electorate—is increasingly accepted as a legitimate political aim, but also remains contested. This chapter sets out key reasons why this aspect of representation matters,

On the Description and Representation of Arabic

Journal of the American Oriental Society, 1997
In Modern Arabic, Clive Holes suceeds in detailing present-day Arabic in all of its variety. Yet, in drawing conclusions regarding several important points, he fails to consider fully and objectively some of the data he himself presents in the study, due partly to his uncritical acceptance of certain widely-held but often unexpressed notions about ...

Description of switched systems by implicit representations

2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012
This paper shows that a certain class of time-dependent, autonomous switched systems can also be studied using the structural concepts and properties of the linear time-invariant implicit systems theory. We first consider the modeling aspects, and then, the control aspects are tackled.
