1. Select an image and perform DCT block operations (dividing image into 8×8 blocks, applying DCT transform to each block). 2. Use masking matrix for DCT coefficient region selection, perform inverse DCT to reconstruct original image, and calculate PSNR of synthesized image. 3. Choose a wavelet function to decompose an image, display transform coefficients to observe patterns, and perform inverse wavelet transform for image reconstruction.

Fusion of two grayscale images using wavelet transform: Perform 2-level decomposition on image 1 with sym4 wavelet function, then process decomposition coefficients for fusion by emphasizing contours and suppressing details. Apply 2-level decomposition with sym4 wavelet to image 2. Finally, fuse images in wavelet transform domain and reconstruct fused coefficients. Implementation involves wavelet decomposition, coefficient processing, and inverse wavelet transform.
