Abstract
In an example embodiment a method, apparatus and computer program product are provided. The method includes calculating directionality values for pixels of a first image and pixels of a second image, where a directionality value for a pixel is calculated based on gradient differences between the pixel and a plurality of neighboring pixels. The method includes determining a plurality of similarity values between the first image and the second images for a plurality of alignment positions of the first image and the second image based on the directionality values for the pixels of the first image and the directionality values for corresponding pixels of the second image. The method further includes selecting an alignment position from among the plurality of alignment positions for aligning the first image and the second image based on comparison of the plurality of similarity values.
