| Abstract: | The article discusses how to improve the detection probability of small targets in the complicated background of low signal noise ratio. The purpose for inhibiting background noise and enhancing small targets is carried out through improving image quality by means of digital filtering and enlarging signal noise ratio. In accordance with the characteristics of high frame TV system, Field Programmable Gate Arrays (FPGA) are applied to construction high speed image preprocessor and real time calculation for image preprocessing of digital TV, and then lay a good basis for the follow up work. The simulation and experimental results demonstrate that this method is feasible. |
