Using the forest to see the trees: exploiting context for visual object detection and localization

Abstract: Recognizing objects in images is an active area of research in computer vision. In the last two decades, there has been much progress and there are already object recognition systems operating in commercial products. However, most of the algorithms for detecting objects perform an exhaustive search across all locations and scales in the image comparing local image regions with an object model. That approach ignores the semantic structure of scenes and tries to solve the recognition problem by brute force. In the real world, objects tend to covary with other objects, providing a rich collection of contextual associations. These contextual associations can be used to reduce the search space by looking only in places in which the object is expected to be; this also increases performance, by rejecting patterns that look like the target but appear in unlikely places. Most modeling attempts so far have defined the context of an object in terms of other previously recognized objects. The drawback of this approach is that inferring the context becomes as difficult as detecting each object. An alternative view of context relies on using the entire scene information holistically. This approach is algorithmically attractive since it dispenses with the need for a prior step of individual object recognition. In this paper, we use a probabilistic framework for encoding the relationships between context and object properties and we show how an integrated system provides improved performance. We view this as a significant step toward general purpose machine vision systems.

A model for functional reasoning in design

Abstract: : A model of the design process is developed in two stages, corresponding to the task environment of design and the activity of posing and solving design problems. Use of the model with top-down and bottom-up disciplines is discussed. An example of the design of an object using a semi-automated design system based on the model is presented. Several issues raised by the model's qualitative aspects, its suitability to automated design, and lines for further development are discussed. (Author)

Graphical user interface with hierarchical structure for customizable menus and control objects

Abstract: The program code for control objects in a graphical user interface is organized in a multi-level hierarchial structure. At one level of the structure, each different type of control defines a class of objects. The definition of a class includes most, if not all, of the functionality associated with the objects of that class. In addition, the class definition includes the overall structure of the object, such as the relative positions of different elements which make up the object. The actual appearance of these elements is defined by user selectable software that resides at a lower level of the hierarchy. Using this approach, only one instance of the program code which defines the functionality and overall structure of each object is required, resulting in smaller the overall memory requirements of the program code.

iPlasma: An Integrated Platform for Quality Assessment of Object-Oriented Design.

Abstract: To make software maintenance easier, a superior quality of its design and implementation process must be ensured. For this reason, existing software must be supported by automated systems for analysis, diagnose and design improvement, at a high level as well as at a level close to source code. iPlasma is an integrated environment for quality analysis of objectoriented software systems that includes support for all the necessary phases of analysis: from model extraction (including scalable parsing for C++ and Java) up to high-level metricsbased analysis, or detection of code duplication. iPlasma has three major advantages: extensibility of supported analysis, integration with further analysis tools and scalability, as it was used in the past to analyze large-scale projects in the size of millions of code lines (e.g. Eclipse and Mozilla).

Faunus: An object oriented framework for molecular simulation.

Abstract: We present a C++ class library for Monte Carlo simulation of molecular systems, including proteins in solution. The design is generic and highly modular, enabling multiple developers to easily implement additional features. The statistical mechanical methods are documented by extensive use of code comments that – subsequently – are collected to automatically build a web-based manual. We show how an object oriented design can be used to create an intuitively appealing coding framework for molecular simulation. This is exemplified in a minimalistic C++ program that can calculate protein protonation states. We further discuss performance issues related to high level coding abstraction. C++ and the Standard Template Library (STL) provide a high-performance platform for generic molecular modeling. Automatic generation of code documentation from inline comments has proven particularly useful in that no separate manual needs to be maintained.
