Abstract
In accordance with an example embodiment a method, apparatus and computer program product are provided. The method comprises extracting a set of image features from a first image and a corresponding set of image features from a second image. A first transformation matrix and a second transformation matrix are computed between the first image and the second image based on a matching of the set of image features in the first image with the corresponding set of image features in the second image. A first set of feature points is determined based on the first transformation matrix, and a second set of feature points based on the second transformation matrix. A transformation matrix is estimated between the first set of feature points and the second set of feature points. The second image is aligned with the first image based on the transformation matrix.
