GARCES-SOCARRAS, Luis Manuel; SANCHEZ-SOLANO, Santiago; BROX JIMENEZ, Piedad  and  CABRERA SARMIENTO, Alejandro José. Library for model-based design of image processing algorithms on FPGAs. Rev.fac.ing.univ. Antioquia [online]. 2013, n.68, pp.36-47. ISSN 0120-6230.

This paper describes a library (XSGImgLib) that includes parameterizable blocks to implement low-level image processing tasks on FPGAs. A model­based design technique provided by Xilinx System Generator (XSG) has been used to design the blocks, which implement point operation (binarization) and neighborhood operations (linear and non-linear filtering) in grayscale images. The blocks are parameterizable for input/output data precision, window size, normalization strategy, and implementation options (area versus speed optimization). The paper includes the implementation results obtained after fixing these options and exemplifies the combination of several blocks of the library to build a complete design for image segmentation purposes.

Keywords : Digital image processing; fpga; xilinx system generator; MATLAB/Simulink.
