By defining a region smoothness measure, the method firstly enhances peak-valley feature of image histogram by fuzzy set technique, and then segments image using adaptive multi-thresholding method.
Peak detector circuit is a fast adaptive detector circuit, and the limiting amplifier involves two stage differential amplifiers.
峰值检波采用自适应检波电路，限幅放大器采用两级差分放大器构成。

The performance of the adaptive binarization thresholding method has been compared with that classical optical correlator in the areas of correlation peak to and SNR (signal to noise ratio).
