文摘
- •
A combination of edge information and visual saliency can preserve the image content better.
- •
Gradient that apply pixel difference in single direction shows better result than in both for image retargeting.
- •
Deleting seams in one direction and duplicating seams in the other can change the aspect ratio even more while preserving the content.
- •
Combining seam carving and scaling can achieves better performance than single discrete or continuous operator.
