Abstract：An improved fast independent component analysis (ICA) feature extraction algorithm is proposed based on one dimension search and distance function. Aiming at the problem that the selection of the initial value influences the convergence in fast ICA algorithm, the improved algorithm ensures the good convergence result by using one dimension search. Meanwhile, a rule based on distance function is designed to select the optimal features for the recognition according to the characteristics of the infrared image. Thus, the problem of the recognition rate and the robustness decreasing with the increasing number of training image samples is resolved. Compared with the traditional methods, the experimental results of real infrared images show that the proposed algorithm reaches a lower error classification rate with fewer infrared object features, and the error classification rate of the proposed method is robust in different kinds of classes.
