Field programmable gate arrays (FPGAs) are introduced as a technology that provides flexible fine grained hardware that can readily exploit parallelism within many image processing algorithms. A brief review of FPGA programming languages provides the link between a software mindset normally associated with image processing algorithms and the hardware mindset required for efficient utilization of a parallel hardware design. The design process for implementing an image processing algorithm on an FPGA is compared with that for a conventional software implementation with the key differences highlighted. Particular attention is given to the techniques for mapping an algorithm onto an FPGA implementation considering timing memory bandwidth and resource constraints and efficient hardware computational techniques. Extensive coverage is given of a range of low and intermediate level image processing operations discussing efficient implementations and how these may vary according to the application. The techniques are illustrated with several example applications or case studies from projects or applications the author has been involved with. Issues such as interfacing between the FPGA and peripheral devices are covered briefly as is designing the system in such a way that it can be more readily debugged and tuned.. Provides a bridge between algorithms and hardware. Demonstrates how to avoid many of the potential pitfalls. Offers practical recommendations and solutions. Illustrates several real world applications and case studies. Allows those with software backgrounds to understand efficient hardware implementationDesign for Embedded Image Processing on FPGAs is ideal for researchers and engineers in the vision or image processing industry who are looking at smart sensors machine vision and robotic vision as well as FPGA developers and application engineers.The book can also be used by graduate students studying imaging systems computer engineering digital design circuit design or computer science. It can also be used as supplementary text for courses in advanced digital design algorithm and hardware implementation and digital signal processing and applications.Lecture slides for instructors available at:www.wiley.com go bailey fpga
