Chapter 14. Image Mosaic/panorama

정의 : Stitch multi-images into a seamless composite

SIFT & SURF의 응용

접점 부분에 Blending 기술(=stitching) 적용

2D 수행 절차

1. Take image sequence from the same scene
   • Global alignment of the images spatially
2. Warp the image pair
   • Compute 2D/3D projective transformation of images
   • Reprojection onto mosaic surface
3. Local Alignment
   • Move warped images to overlap exactly
4. Stitching(Optional) : 경계선 찾기
   • Find boundary between overlapped images
   • 길찾기 문제와 비슷
5. Composition of the warped images
   • Blend the two together to create a mosaic
