Design two matlab algorithms for enlarging the 256x256 images into 512x512 images by using bilinear and bicubic interpolations
a) Evaluate the interpolated images with the original 512x512 images by using the PSNR and SSIM.
b) Try to better the PSNR and SSIM of the interpolated images by:
-Using sharpening filters
-Adding some random noise to interpolated images
c) Illustrate your own spatial domain interpolation algorithm and assess its performance
