Visual development environment for OpenVX

Abstract

OpenVX standard has appeared as an answer from the computer vision community to the challenge of accelerating vision applications on embedded heterogeneous platforms. It is designed as a low-level programming framework that enables software developers to leverage the computer vision hardware potential with functional and performance portability. In this paper, we present the visual environment for OpenVX programs development. To the best of our knowledge, this is the first time the graphical notation is used for OpenVX programming. Our environment addresses the need to design OpenVX graphs in a natural visual form with automatic generation of a full-fledged program, saving the programmer from writing a bunch of a boilerplate code. Using the VIPE visual IDE to develop OpenVX programs also makes it possible to work with our performance analysis tools. All the benefits gained from using the visual IDE are illustrated by the feature tracker example.
