Claim 0:
1. An image stitching method, comprising:
obtaining a plurality of images at different viewpoints;
estimating homographies of the plurality of images;
generating an aligned image by aligning the plurality of images based on the homographies of each of the plurality of images;
obtaining a collective energy map by inputting the aligned image to a neural network;
estimating a stitching line of the aligned image based on the collective energy map; and
generating a stitched image by blending the aligned image based on the stitching line,
wherein the collective energy map combines an energy map using a gradient, an energy map using a motion, an energy map using object segmentation, and an energy map using distance transformation of object segmentation, and
wherein the image stitching method estimates the stitching line as a path having a minimum energy or a maximum energy.
