Modular Architecture For Real-Time Video Processing

The increase in the development of techniques and equipments for image processing purposes has allowed the study of new applications for automatic vision. In many cases, the need of real time image processing functions leads to a heavy and high cost equipment, which reduces the number of industrial applications. This paper presents a new concept of image processing hardware to be used in real time operations at low cost. The system hardware named HARVIS is based on only one board which is able to execute one function over all the images in one video frame. The function is hardware selectable among several available configurations. The paralell or sequencial association of the necessary boards allows some complex functions to be performed at video frame speed. In this paper the application of this modular architecture to automatic surveillance executed by vision cameras in an open space environment is described.
