Abstract
An FPGA-based approach is proposed to build an augmented reality system in order to aid people affected by a visual disorder known as tunnel vision. The aim is to increase the user's knowledge of his environment by superimposing on his own view useful information obtained with image processing. Two different alternatives have been explored to perform the required image processing: a specific purpose algorithm to extract edge detection information, and a cellular neural network with the suitable template. Their implementations in reconfigurable hardware pursue to take advantage of the performance and flexibility that show modern FPGAs. This paper describes the hardware implementation of both the Canny algorithm and the cellular neural network, and the overall system architecture. Results of the implementations and examples of the system functionality are presented.
