Abstract

In the technique on the detecting and the identifying of infrared target, the infrared target and the background can be distinguished by the difference of the gray-scale, i.e. the difference in temperature between them. Firstly, FPGA was used to pre-treat the infrared image including the threshold segmentation of two-apex and the threshold segmentation of maximum between-cluster variance. Secondly, the figure of the target was obtained, and then the binary image was transferred to the DSP which identified it. The high efficiency of FPGA in simple-shape computing of digital signal processing was stood out.
