Abstract
An image stitching method includes: obtaining a first and a second images; selecting a first and a second search regions from the first and second images, respectively, the first and second search regions at least partially overlapping with each other along a first direction; dividing each of the first and second search regions into a plurality of equally-sized pixel blocks; moving the first and second images toward each other along the first direction using the pixel blocks as a step size, until each of the first and second search regions has been traversed; after each movement, determining a pixel difference value representing a difference between all overlapping pixel blocks of the first search region and the second search region; determining an optimal block-matching position for the first and second images based on the pixel difference value; and stitching the first and second images according to the optimal block-matching position.
