WebDCT based image fusion produced results but with lesser clarity, less PSNR value and more Mean square error. Therefore the overall objective is to improve the results by combining DCT with PCA and non-linear enhancement. The proposed algorithm is designed and implemented in MATLAB using image processing toolbox. WebIn particular, the combined feature vectors with PCA revealed a statistically significant improvement in classification accuracy compared to DWT (p < 0.05) and CWT (p < 0.05). Although accuracy was reduced compared to CWT for Subject 4, improved accuracy was observed for the other subjects.
