LOPEZ-PORTILLA VIGIL, Bárbaro M; MENENDEZ ALONSO, Reinaldo J.  y  IGLESIAS MARTINEZ, Miguel E.. Otsu’s algorithm implementation on FPGA. Rev cuba cienc informat [online]. 2016, vol.10, n.3, pp.16-26. ISSN 2227-1899.

ABSTRACT In this paper, the implementation of a system used for detecting the optimal threshold in grayscale 256x256 images based on the Otsu's algorithm is described. The proposed system is based on a hybrid hardware-software implementation, where the main module of the hardware part is precisely the proposed architecture that corresponds with the Otsu's algorithm. One advantage of this implementation is that the use of dividers and almost all the multipliers are avoided. For the implementation a Digilent Nexys2 Board that containing a FPGA Xilinx XCS500E is used. The results are satisfactory in terms of accuracy and number of internal FPGA resources occupied.
