Abstract
An image processing apparatus includes a first processor configured to obtain, from a color image, an illumination element image and an albedo element image corresponding to the color image, and a second processor configured to divide the illumination element image into a plurality of subelement images each corresponding to the color image.
Claims20
An image processing apparatus comprising:
- a first processor configured to obtain, from a color image, an illumination element image and an albedo element image corresponding to the color image;
- and
- a second processor configured to divide the illumination element image into subelement images each corresponding to the color image.
An image processing apparatus comprising:
- a first processor configured to obtain, from a color image, an illumination element image and an albedo element image corresponding to the color image;
- and
- a second processor configured to calculate a normal vector corresponding to each pixel of the illumination element image using a depth image corresponding to the color image, cluster the illumination element image to at least one pixel group based on a normal vector change rate between neighboring pixels in the illumination element image, and to divide the illumination element image into subelement images based on comparing an illumination element change rate between neighboring pixels in the at least one pixel group to a normal vector change rate of the pixel group.
An image processing method comprising:
- obtaining, from a color image, an illumination element image and an albedo element image corresponding to the color image;
- and
- dividing the illumination element image into subelement images each corresponding to the color image.
