The point target detection application is widely applied to the field of medicine, military, and astronautics. To support good detectability of point targets and high-performance computing, this work proposes a point target detection system (PTDS) and a reconfigurable point target detection system (RePTDS). In the PTDS and the RePTDS, we propose a pipelined morphological clutter elimination (PMCE) hardware design that supports the point target detection application. Further, we also propose a hardware/software interface component that provides seamless data transfers between the PMCE hardware design and the microprocessor. To reduce the effects of the noise in the source images, different median filter functions are also designed in the PTDS and the RePTDS individually. Both the PTDS and the RePTDS can dynamically adapt their median filter functions to reduce the noise of the source images. Besides providing good detectability of point targets, according to our experiments, the PTDS and the RePTDS have been demonstrated that they can accelerate up to 165 times the processing time required by using the conventional point target detection method. Further, compared to the PTDS, our experiments have also demonstrated the RePTDS can provide more complete support of system adaptability for hardware functions, performance, and power consumption.
