Abstract
The disclosure relates to an information processing apparatus and an information processing method. The information processing apparatus includes a processing circuitry configured to: obtain a normal map of an object based on depth data of the object; determine a normal angle of a pixel in the normal map, wherein the normal angle being an angle between a normal vector of the pixel and an average normal vector of a patch with a predetermined size centered on the pixel; identify, in the normal map, a patch in which normal angles of pixels conform to a predetermined distribution pattern; and adjust the normal angle of a pixel in the identified patch to obtain the optimized normal map.

An information processing apparatus, comprising:
- processing circuitry configured to
- obtain a normal map of an object based on depth data of the object;
- determine a normal angle of a pixel in the normal map, wherein the normal angle is an angle between a normal vector of the pixel and an average normal vector of a patch with a predetermined size centered on the pixel;
- identify, in the normal map, a patch in which normal angles of pixels conform to a predetermined distribution pattern;
- and
- adjust the normal angle of a pixel in the identified patch to obtain an optimized normal map,
- wherein the predetermined distribution pattern comprises values of the normal angles of pixels arranged along a predetermined direction in the patch present a single-peak distribution.
