Yayın Realization of preprocessing blocks of CNN based CASA system on FPGA(2013) Şavkay, Osman Levent; Yıldız, Nerhun; Cesur, Evren; Yalçın Müştak, Erhan; Tavşanoğlu, Ahmet VedatIn this paper, hardware optimization of the preprocessing part of a computer aided semen analysis (CASA) system is proposed, which is also implemented on an FPGA device as a working prototype. A real-time cellular neural network (CNN) emulator (RTCNNP-v2) is used for the realization of the image processing algorithms, whose regular, flexible and reconfigurable infrastructure simplifies the prototyping process. For future work, the post-processing part of the CASA system is proposed to be implemented on the same FPGA device as software, using either a soft or hard processor core. By the integration of the pre- and post-processing parts, the designed CASA system will be capable of processing full-HD 1080p@60 (1080×1920) video images in real-time.
