An Interactive Programming System for Media

نویسنده

  • David Wetherall
چکیده

This paper presents PAVES, a direct manipulation system that combines aspects of visualization and mul-timedia systems to form an interactive video programming environment. PAVES extends the VuSystem media processing toolkit with dataaow-style views for controlling compute-intensive media applications as they run. Thus video may be manipulated graphically and interactively | both program and data are visual and live. PAVES is also novel in its approach to exten-sibility. Users may freely combine graphical and underlying VuSystem textual programming methods to restructure and reuse applications. This cooperative programming is available across sessions as well as within them. It is implemented with an object-oriented programming foundation that automatically translates between multiple program representations and maintains them in synchrony.

Interactive multiple objective programming in optimization of the fully fuzzy quadratic programming problems

In this paper, a quadratic programming (FFQP) problem is considered in which all of the cost coefficients, constraints coefficients, and right hand side of the constraints are characterized by L-R fuzzy numbers. Through this paper, the concept of α- level of fuzzy numbers for the objective function, and the order relations on the fuzzy numbers for the constraints are considered.  To optimize th...
