| Abstract: | In this paper, a method of feature extraction from images is presented based on the principle of the image compression of fast G wavelet transformation. Good results were obtained when the extracted image features were used in the training of feed forward neural networks and the identification. |
| Keywords: | G wavelet transformation G wavelet basic function feature extraction neural network genetic algorithm |
