| Abstract: | Dim target detection and location from infrared image is studied. Dim target can be regarded as transient signal with unknown intensity and location, and it belongs to high frequency part of the image. By multi resolution wavelet transform for the image, dim target in the condition of low SNR could be detected. The experiment results indicate that wavelet transform can enhance the target and suppress background clutter effectively, and improve the target detection probability and reduce the detection error. |
