Image stitching based on angle-consistent warping
作者：
Highlights：
• Angle features are discovered as geometric constraints for image warping.
• A stitching framework incorporating the angles is proposed to improve the alignment of images.
• We reveal that angles can provide guidance for homography as coordinates do.
• A novel constraint on mesh angles makes stitching results in non-overlapping areas more natural.
• The proposed framework exhibits superior performance, especially in areas with small objects or few feature points.
