Application of SiDWT with extended PCA for multi-focus images

An Image is a representation of the information in visual form. The quality of the image acquired depends greatly on the type of image acquisition systems. Sometimes these systems fail to give the good results and we need to process the image to get the desired information. In this paper we will discuss the Multi-focus images and their fusion. A multi-focus image is the result of the inability of the acquisition system to acquire the image up to the desired field of depth. So here we are trying to find a best solution for fusion of multi-focus images considering the simplicity of algorithm with respect to different quantitative measures. In our previous work we have worked on the multimodality image fusion with image database of CT and MRI machines to combine complementary information from two images. Now in current work we are trying to extend the application of the proposed method to Multi-focus images. It will be a pixel level approach.
