Method and apparatus for stitching frames of image comprising moving objects

An electronic device configured to generate a stitched image, the electronic device comprising:

• memory storing instructions;
• and
• at least one processor, comprising processing circuitry, coupled to the memory, wherein the instructions, when executed by the at least one processor, cause the electronic device to:
• obtain an input stream including a plurality of frames through an image capturing device;
• identify one or more moving objects and one or more timestamps associated with movement of the one or more moving objects from a first frame and a second frame selected among the plurality of frames;
• determine a plurality of attributes associated with the one or more moving objects from at least one overlapping region of the first frame and the second frame;
• normalize the determined plurality of attributes with respect to a plurality of device attributes associated with the image capturing device;
• determine a trajectory, associated with the one or more moving objects and a moving region of the one or more moving objects in the first frame and the second frame based on the normalized plurality of attributes;
• perform one of:
• stitching the first frame at a first location of the at least one overlapping region where the one or more moving objects are present, wherein the trajectory from the first frame is masked to regenerate a masked portion of the second frame, and
• stitching the first frame at a second location of the at least one overlapping region where the one or more moving objects are not present, wherein the trajectory from the first frame is masked to regenerate a masked portion of the second frame;
• and
• generate the stitched image by stitching the first frame with the masked portion of the second frame.

A non-transitory computer-readable storage medium storing instructions which, when executed by at least one processor of an electronic device, cause the electronic device to perform operations comprising:

• obtaining an input stream including a plurality of frames through an image capturing device;
• identifying one or more moving objects and one or more timestamps associated with movement of the one or more moving objects from a first frame and a second frame selected among the plurality of frames;
• determining a plurality of attributes associated with the one or more moving objects from at least one overlapping region of the first frame and the second frame;
• normalizing the determined plurality of attributes with respect to a plurality of device attributes associated with the image capturing device;
• determining a trajectory, associated with the one or more moving objects and a moving region of the one or more moving objects in the first frame and the second frame based on the normalized plurality of attributes;
• performing one of:
• stitching the first frame at a first location of the at least one overlapping region where the one or more moving objects are present, wherein the trajectory from the first frame is masked to regenerate a masked portion of the second frame, and
• stitching the first frame at a second location of the at least one overlapping region where the one or more moving objects are not present, wherein the trajectory from the first frame is masked to regenerate a masked portion of the second frame;
• and
• generating the stitched image by stitching the first frame with the masked portion of the second frame.
