Binary image processing is a powerful tool in many image and video applications. A reconfigurable processor is presented for binary image processing in this paper. The processor’s architecture is a combination of a reconfigurable binary processing module, input and output image control units, and peripheral circuits. The reconfigurable binary processing module, which consists of mixed-grained reconfigurable binary compute units and output control logic, performs binary image processing operations, especially mathematical morphology operations, and implements related algorithms more than 200 f/s for a 1024 ×1024 image. The periphery circuits control the whole image processing and dynamic reconfiguration process. The processor is implemented on an EP2S180 field-programmable gate array. Synthesis results show that the presented processor can deliver 60.72 GOPS and 23.72 GOPS/mm2 at a 220-MHz system clock in the SMIC 0.18-μm CMOS process. The simulation and experimental results demonstrate that the processor is suitable for real-time binary image processing applications.Keywords

Penaeus (Litopenaeus) vannamei shrimp samples (hepatopancreas and faeces) collected from grow-out farms were evaluated for the presence of newly emerged microsporidian parasite Enterocytozoon hepatopenaei by concentration techniques using either water–ether sedimentation or Sheather’s sugar solution for spore recovery and subsequent microscopic detection by modified trichrome stain (Ryan-blue method). This improved selective staining protocol can easily resolve the identification of microsporidian spores in hepatopancreatic tubules compared to conventional stains. This method enables differential diagnosis of microsporidian spores by a characteristic staining pattern of pinkish-red, often with a belt-like diagonal stripe seen in the middle of the spore and a halo of unstained area at one end which could be easily distinguished from similarly staining particles or debris.Keywords
