Haar Wavelet Transform of an Image

Multi-resolution Image Analysis using Haar Wavelet Transformation and Performing Inverse Transformation to Restore Original Image.

Basic Concept (SUMMARY)
1. Read an Input Image
2. Resizing the Image to 1024 x 1024 Image
3. Defining the Haar Filter Matrix { 1/sqrt(2)*[1 1; 1 -1] }
4. Performing Filtering
Along Colms and then Along Rows and downsample by 2
Updating the Output Image iteratively
5. Display of Multiresolution Image
6. Performing Restoration
Along Rows and then Along Colms and upsampling by 2
Updating the Output Image iteratively
7. Display the Final Restored Img
