Effect of spider-web-plot in MR brain image classification

This letter researched on the effect of spider-web-plot, which was proposed in the literature \"M. Saritha, K.P. Joseph, A.T. Mathew, Classification of MRI brain images using combined wavelet entropy based spider web plots and probabilistic neural network, Pattern Recognit. Lett. 34 (2013) 2151-2156\". We found it was unnecessary to use spider-web-plot as feature transform method. In addition, our simulation results showed that removing the procedure of spider-web-plot yielded the same classification accuracy of 100%.
