Abstract
This paper presents an image blending approach which combines optimal seam finding and transition smoothing for merging a set of aligned source images into a composite panoramic image seamlessly. In this approach, graph cut optimization is used for finding optimal seams in overlapping areas of the source images to create a composite image. If the seams in the composite image are still visible, a gradient domain transition smoothing operation is used to reduce color differences between the source images to make them invisible. In the transition smoothing operation, a new gradient vector field is created using the gradients of source images and the seam information. A new composite image can be recovered from the new gradient vector field by solving a Poisson equation with boundary conditions.
