The system is able to process hundreds of megabytes of image data per second coming from several high-speed high-resolution cameras. Due to performance requirements some functionality has been implemented on dedicated hardware based on a field programmable gate array FPGA which is coupled to a high-end digital signal processor DSP . The paper discusses design considerations like partitioning of image processing algorithms between hardware and software. The main chapters focus on functionality implemented on the FPGA including low-level image processing algorithms flat-field correction image pyramid generation neighborhood operations and advanced processing units programmable arithmetic unit geometry unit . Verification issues for the complex system are also addressed. The paper concludes with a summary of the FPGA resource usage and some performance results. Copyright 2007 Johannes Furtler et al.
