This paper studies a variety of fuzzy signal, analyzes the uncertainties classification and their influence, implements to eliminate fuzziness processing, and compares with other methods on image processing with the combining method of simulation and instance experiments, this paper systematically analyzes the validity of the model and algorithms. Moreover, using the wavelet transform to carry out decompose the image, this paper extracts the wavelet coefficient and energy feature, gives the matching and recognition methods, and compares with the existing target recognition methods by experiment. Through experiment results, the proposed recognition method has the high precision, fast speed, which improves an average 5.16 % than that of existing recognition methods. These researches development in this paper can provide an important theoretical reference and practical significance to improve the real-time and accuracy on fuzzy target recognition.
