The target growing effect and large calculation are two major drawbacks in small target detection based on the self-information map. Consequently, a weighted self-information map is proposed to overcome those disadvantages in this paper. The removal of the target growing effect from the weighted self-information map is proved theoretically, which is capable of improving the capability of small target detection. Based on the weighted self-information map and the improved region growing technology, a small-target detection approach is constructed...
