Dwt and improved pca

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. WebVIII. LPG-PCA denoising algorithm: Principal component analysis was developed by famous personalities the Pearson and the Hotelling, whilst the best modern reference is Jolli ffe [2]. PCA is a method of identifying patterns in data, and expressing the data in such a way as to highlight their similarities and differences.
