What is a seam carving?
Seam carving is a method for resizing images to a desired target size with the goal of preserving the contents of the image. Introduced by Avidan & Shamir [1],it is a content-aware procedure that supports reduction and expansion.
What is seam carving for content aware image resizing?
Seam carving uses an energy function defining the importance of pixels. A seam is a connected path of low energy pixels crossing the image from top to bottom, or from left to right. By successively removing or insert- ing seams we can reduce, as well as enlarge, the size of an image in both directions (see Figure 1).
How is the energy of a pixel determined in the context of seam carving?
Find the cumulative energies for all pixels along a seam starting from the second row using the formula below: M[i,j] = E[i, j] + min(M[i - 1, j - 1], M[i - 1, j], M[i - 1, j + 1]) , where M is the matrix of cumulative energies and E is the energy for any pixel located at row i and column j, and the first row of M is ...
