Image Resolution Enhancement Using PCA Based Post Filtering
Qiang Guo, Qiang Guo, Ya Chen · Research Journal of Applied Sciences Engineering and Technology · 2013
In this study an image resolution enhancement method is presented that uses the NEDI method to generate an initial image. To increase the detail of this initial image, the given low resolution image is fused with it to achieve a new image. Then the final high resolution image is obtained by using a PCA based filtering to reduce the distortion of this new image. Experimental results on test images demonstrate that the proposed method provides competitive performance.
