摘要
A novel coarse-to-fine approach to extract an infrared target is proposed. First, a confined region which contains the entire object is obtained based on the weighted information entropy feature. Secondly, according to the confined region, the energy function is constructed by combining boundary and region properties of the target region. Finally, the target is accurately extracted by energy minimisation as a graph cut problem. The experimental results show that the proposed method is robust and effective.
