| Abstract: | A new small target detection approach is presented which is based on multi scale background texture analysis. Through multi scale wavelet decomposition of background textures and local energy calculation, feature vectors of each point is obtained. According to these feature vectors, a distance map corresponding to these features can be derived and the target detection is performed on this distance map. The histogram of distance map is employed for the automatic selection of threshold value. The experiments show that this approach can give quite satisfactory results. |
