Image Classification by Combining Wavelet Transform and Neural Network

In this paper, we propose a method of classification of image by combining wavelet transform and neural network. Our main objective in this work is to achieve an optimal approach of classification by combining wavelet transform and neural network. The proposed scheme for successful classification is combination of a wavelet domain feature extractor and back propagation neural networks (BPNN) classifier [6]. This new approach of classification of image is based on the texture, information of colour and shape. For achieving a suitable way for classification of image here we first use wavelet transform which will decompose our main image into sub image [10] and after that this decomposed image are in turn analyzed and finally features are extracted. In this proposed method of image classification first we divide all given image into six parts. For obtaining the necessary and required information from each part of the given divided image we use first order movements of colour [9] and daubechies 4 types of wavelet transform. This proposed method for classification of image is fully based on back propagation neural network. The highly adaptive and parallel processing ability of back propagation neural network make it widely used classifiers. The RGB colour movement and decomposition coefficient which obtained from each The highly adaptive and parallel processing ability of back propagation neural network make it widely used classifiers. The RGB colour movement and decomposition coefficient which obtained from each parts of image by using wavelet decomposer is used as input vector for neural network [9].170 aircraft colour image were used for training and 200 for testing. Resulting data consist of 98% and 90% efficiency for training and testing respectively.
