ABSTRACT

This report discusses the use of the DeAnza IP6400 2 image processor for high speed local window operations. A system overview of the image processor and its important features are first introduced. Algorithms for linear and non-linear window operators are then presented.

[ Chapter ] 1. Introduction

Most image processing operations take a large amount of memory space and cpu time. General purpose computers are not usually equipped with features necessary for high speed image processing operations. Nowadays, high speed image processing is desirable in many industrial and medical applications. The DeAnza IP6400 is used for its special features that make real time processing feasible. This report will first introduce an overview of the IP6400, and its most important option, the digital video processor (DVP), which provides facilities for various processing operations. Algorithms using the IP6400 to perform general 3*3 local window operations, n*m local window operations, 3*3 median filtering, and n*m median filtering are then presented.

THE USE OF THE DEANZA IP6400 IMAGE PROCESSOR FOR LOCAL WINDOW OPERATIONS

2.1. The DeAnza IP6400

The IP6400 Series Image Array Processor contains many features which make it a powerful imaging system. It can be used solely as a display system which provides high resolution color, pseudo color, and multiple monochrome image display. Coupled with other options, real time image processing can be achieved using the IP6400. Among the options acquired in our system are a video signal digitizer and control, alphanumeric overlay generator, graphic overlay channel, trackball cursor generator and control, joystick cursor generator and control, external synchronous source input, video output controller, and, most of all, the digital video processor arithmetic unit which makes window operations feasible. Our system also contains four 512*512 8-bit memory planes and four video cards with 8 bit DAC's. It is interfaced with a VAX 11/780 host computer running UNIX 3 (4.1bsd). Figure 1 shows...
