Hardware Implementation for Edge Detection in cDNA Microarray Images

The present paper proposes hardware implementation strategies for cDNA microarray image processing in order to overcome the main disadvantage introduced by the existing computational tools, the increased processing time. A hardware implementation of the Canny edge detection algorithm for microarray spots is described. The implementation takes advantage of spatial and temporal parallelism offered by FPGA technology. Results of the hardware implementation which prove time and cost efficiency are presented.
