TL;DR: The object graph enables predictions for accurate ICP-based camera to model tracking at each live frame, and efficient active search for new objects in currently undescribed image regions, as well as the generation of an object level scene description with the potential to enable interaction.
Abstract: We present the major advantages of a new 'object oriented' 3D SLAM paradigm, which takes full advantage in the loop of prior knowledge that many scenes consist of repeated, domain-specific objects and structures. As a hand-held depth camera browses a cluttered scene, real-time 3D object recognition and tracking provides 6DoF camera-object constraints which feed into an explicit graph of objects, continually refined by efficient pose-graph optimisation. This offers the descriptive and predictive power of SLAM systems which perform dense surface reconstruction, but with a huge representation compression. The object graph enables predictions for accurate ICP-based camera to model tracking at each live frame, and efficient active search for new objects in currently undescribed image regions. We demonstrate real-time incremental SLAM in large, cluttered environments, including loop closure, relocalisation and the detection of moved objects, and of course the generation of an object level scene description with the potential to enable interaction.

TL;DR: Ownership types form a static type system that indicates object ownership, which provides a flexible mechanism to limit the visibility of object references and restrict access paths to objects, thus controlling a system's dynamic topology.
Abstract: Object-oriented programming languages allow inter-object aliasing. Although necessary to construct linked data structures and networks of interacting objects, aliasing is problematic in that an aggregate object's state can change via an alias to one of its components, without the aggregate being aware of any aliasing.Ownership types form a static type system that indicates object ownership. This provides a flexible mechanism to limit the visibility of object references and restrict access paths to objects, thus controlling a system's dynamic topology. The type system is shown to be sound, and the specific aliasing properties that a system's object graph satisfies are formulated and proven invariant for well-typed programs.

TL;DR: A method is presented for explicitly representing dimensions, tolerances, and geometric features in solid models in a graph structure called an object graph that provides an important foundation for higher-level application programs to automate tolerance analysis and synthesis.
Abstract: A method is presented for explicitly representing dimensions, tolerances, and geometric features in solid models. The method combines CSG and boundary representations in a graph structure called an object graph. Dimensions are represented by a relative position operator. The method can automatically translate changes in dimensional values into corresponding changes in geometry and topology. The representation provides an important foundation for higher-level application programs to automate tolerance analysis and synthesis. The implementation of a prototype interactive polyhedral modeler based on this representation is presented. >

TL;DR: In this paper, the compiler/decompiler API of a Java Virtual Machine (JVM) can be used for compiling objects (e.g. Java Objects) into data representation language representations of the objects, and for decompiling representations of objects into objects.
Abstract: A virtual machine (e.g. the Java Virtual Machine (JVM)) may include extensions for compiling objects (e.g. Java Objects) into data representation language (e.g. XML) representations of the objects, and for decompiling representations of objects into objects. The virtual machine may supply an API to the compilation/decompilation extensions. The compiler/decompiler API may accept an object as input, and output a data representation language representation of the object and all its referenced objects (the object graph) in a data stream. In addition, the compiler/decompiler API may accept a data stream, which includes a representation of the object and all its referenced objects (the object graph), and output the object (and all the objects in its object graph). In one embodiment, an intermediary format may be used to represent a data representation language document and may be dynamically processed to generate a class instance from the data representation language document.

TL;DR: In this article, a system and method for visualizing objects within an object network is presented, which is based on the concept of graphical user interface (GUI) which consists of a plurality of graphical nodes arranged in a graph structure, each of the nodes representing one of the objects and the graph structure representing the relationships between the objects.
Abstract: A system and method for visualizing objects within an object network. For example, a computer-implemented method according to one embodiment comprises: receiving object graph data from a remote computing system, the object graph data representing characteristics of objects and relationships between objects in object-oriented program code executed on the remote computer system; interpreting the object graph data to determine one or more characteristics of each of the objects; and generating a graphical user interface (“GUI”) comprised of a plurality of graphical nodes arranged in a graph structure, each of the nodes representing one of the objects and the graph structure representing the relationships between the objects, wherein the graphical nodes are rendered with graphical characteristics representing characteristics of the objects which they represent, the graphical characteristics including at least a color and a shape.
