Classification: CPC G | IPC G

Claim 4:
5. An image stitching apparatus, comprising:
at least one processor; and
a memory,
wherein the processor is configured to:
obtain a plurality of images at different viewpoints;
estimate homographies of the plurality of images;
generate an aligned image by aligning the plurality of images based on the homographies of each of the plurality of images;
obtain a collective energy map by inputting the aligned image to a neural network;
estimate a stitching line of the aligned image based on the collective energy map; and

generate 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 apparatus estimates the stitching line as a path having a minimum energy or a maximum energy.
