Image inpainting on arbitrary surfaces

A device for imaging inpainting, the device comprising:

• a memory storing instructions;
• and
• a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the device to:
• obtain a first three-dimensional image, wherein:
• the first three-dimensional image is an image on a surface S in three-dimensional space, and
• each point of the first three-dimensional image comprises an image point value and a position vector in the three-dimensional space,
• determine whether the first three-dimensional image is a grayscale image,
• when it is determined that the first three-dimensional image is the grayscale image:
• locate an inpainting region D of the first three-dimensional image, and
• when it is determined that the first three-dimensional image is not the grayscale image:
• separate the first three-dimensional image into a plurality of color channels wherein each of the plurality of color channels comprises an equivalent grayscale image, and
• for each of the plurality of color channels:
• locate the inpainting region D of the each of the plurality of color channels,
• generate an inpainting mask corresponding to the inpainting region D,
• calculate, according to the inpainting region D, image point values for points inside the inpainting region D, and
• create, based on the calculated image point values for points inside the inpainting region D, a second three-dimensional image on the surface S in the three-dimensional space.

A non-transitory computer readable storage medium storing instructions, wherein the instructions, when executed by a processor, cause the processor to perform:

• obtaining a first three-dimensional image, wherein:
• the first three-dimensional image is an image on a surface S in three-dimensional space, and
• each point of the first three-dimensional image comprises an image point value and a position vector in the three-dimensional space;
• determining whether the first three-dimensional image is a grayscale image;
• when it is determined that the first three-dimensional image is the grayscale image:
• locating an inpainting region D of the first three-dimensional image;
• when it is determined that the first three-dimensional image is not the grayscale image:
• separating the first three-dimensional image into a plurality of color channels wherein each of the plurality of color channels comprises an equivalent grayscale image, and
• for each of the plurality of color channels:
• locating the inpainting region D of the each of the plurality of color channels;
• generating an inpainting mask corresponding to the inpainting region D;
• calculating, according to the inpainting region D, image point values for points inside the inpainting region D;
• and
• creating, based on the calculated image point values for points inside the inpainting region D, a second three-dimensional image on the surface S in the three-dimensional space.
