Special Issue Information

Dear Colleagues,

Field Programmable Gate Arrays (FPGAs) are increasingly being used for the implementation of image processing applications. This is especially the case for real-time embedded applications, where latency and power are important consideration. An FPGA embedded in a smart camera is able to perform much of the image processing directly as the image is streamed from the sensor, providing a processed data stream, rather than images. The parallelism of hardware is able to exploit the spatial and temporal parallelism implicit within many image processing tasks. Unfortunately, simply porting a software algorithm onto an FPGA often gives disappointing results, because many image processing algorithms have been optimised for a serial processor. It is usually necessary to transform the algorithm to efficiently exploit the parallelism and resources available on an FPGA. This can lead to novel algorithms and hardware computational architectures, both at the image processing operation level and also the application level.

The aim of this Special Issue is to present and highlight novel algorithms, architectures, techniques and applications of FPGAs for image processing.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Imaging is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) is waived for well-prepared manuscripts submitted to this issue. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract: Embedded image processing systems presents challenges in terms of computing resources and energy. The paper describes an approach based on an FPGA-based processor called IPPro which can operate up to 337 MHz on Xilinx FPGA families and gives details of the dataflow-based programming environment. The approach is demonstrated for a k-means clustering operation and a traffic sign recognition application, both of which have been prototyped on a Xilinx FPGA-based Zedboard. A number of options were explored giving a speedup of 8 for the k-means clustering using 16 IPPros, and a speedup of 9.6 for the morphology operation of the traffic sign recognition using 16 IPPros when compared to ARM-based software implementations. We show that for k-means clustering, the 8 IPPro version gives a design that is 9.6 times more power efficient than a modern GPU implementation.

Abstract: With the upcoming expected end of Moore's Law, major enhancements in performance and energy consumption of complex algorithms are no longer possible with standard processors alone and increasingly require specialized hardware. The optical recognition of objects under difficult conditions regarding lighting, noise or partial occlusions is a frequently required task in many computer vision applications. This paper reviews a variety of image processing operations related to object and shape recognition together with their optimized FPGA implementations. Several architectural aspects, benefits and trade-offs for using FPGAs are presented and discussed. The operations include feature detection using the SURF point features and variations of the Hough Transform including the Generalized Hough Transform. These operations have been integrated into complete image processing systems using a common framework (ASTERICS).
