Enhancement of Image Fusion Performance Using DDCT and PCA Hybrid Algorithm.

The paper designs a hybrid method for image fusion technique. The proposed algorithm is a combination of Directional Discrete Cosine Transform (DDCT) and Principal Component Analysis (PCA) technique. The proposed algorithm gives better results compared to other traditional techniques like Discrete Wavelet Transform (DWT) and segmentation. The multiple problems in image fusion like image noise, image pixel quality, etc. are identified using image filter. The paper also uses impulse filter to reduce image noise and improve pixel quality. [ABSTRACT FROM AUTHOR]
