| Abstract(in English) | In this paper, a new discriminant function for recognition of noisy patterns is presented. If noise is added to input data, the distribution of feature vectors will change according to the noise. In this case, probability density function of distribution is considered to be necessary to reflect the changes. We investigate how distribution of vectors changes if noise is added to some elements of vectors, and a discriminant function that reflects the changes is proposed. This method supplements the existing statistical methods and has high ability of recognition of data with noise. The effectiveness of the new method is shown by simulations with artificial data and experiments with real blurred character images. |
