Discrete Wavelet Transform (DWT) is applied on the color image. The decomposition level is set to 3. Approximation coefficients are extracted from the decomposed image. Improved Saliency Map (ISM) is computed. Self-Organizing Map (SOM) is trained with approximation coefficients along with ISM values. The resultant image is clustered with EFCM algorithm. Proposed method is validated on Berkeley segmentation dataset and other natural color images. Performance of the method is evaluated by using accuracy, precision, recall, entropy and time. Simulation results showed that the proposed method can achieve good segmentation results with low computational complexity than other methods considered for comparison from the literature.
