The method includes determining the corrected side view image at bird-eye perspective, generating a cost map for overlapping region, finding a minimum cost seam for each overlapping region, computing weight based on distance to the seam, if blending of the pixel, and blending the pixel, synthesizing composite view, and generating a composite view image. | 05-21-2015 |
