Laplacian image blend
1. Compute Laplacian pyramid
2. Compute Gaussian pyramid on weight
image (can put this in A channel)
3. Blend Laplacians using Gaussian blurred
weights
4. Reconstruct the final image
Q: How do we compute the original weights?
A: For horizontal panorama, use mid-lines
Q: How about for a general “3D” panorama?
