Abstract

The mapping of image processing algorithms to hardware is complicated by several hardware constraints including limited processing time, limited access to data and limited resources of the system. These constraints often force the designer to reformulate the algorithm. To aid in the process this paper details the application of design patterns to image processing algorithm development. Design patterns embody experience and through reuse provide tools for solving particular mapping problems. The effectiveness of design patterns for overcoming constraints in the mapping process is illustrated in the context of a real world example that focuses on the development of a real-time object tracking algorithm implemented on an FPGA.
