Realization

• Poisson Blending

• Mixed Blending

Result

1. tree + landscape

Naive

Poisson

Blending

The result isn't ideal. The tree looks not very natural in the image due to

• The tree looks more "green" than the background, apply color transfer might help
• The edge of mask is blur in poisson blending, it's better in the mixed.
• In mixed method, the gradient of background is too big for the foreground, so the left-bottom corner of the foreground looks dark and unnatural
