Abstract: A method and a device for texture filtering include determining an upper mipmap and a lower mipmap based on a level of detail (LOD) value corresponding to a quad, obtaining first color values corresponding to the upper mipmap, obtaining second color values corresponding to the lower mipmap, and obtaining third color values of the pixels of the quad by using linear interpolation, based on the obtained first and second color values.

Abstract: A method of determining a level of detail (LOD) for a texturing includes: acquiring texture coordinate data on pixels included in an upper block; determining a reference quad among quads included in the upper block; determining a similarity between the determined reference quad and the upper block using texture coordinates of the determined reference quad and the upper block; and determining LODs of remaining quads among the quads included in the upper block to be the same as an LOD of the determined reference quad in response to the determining of the similarity including determining that the determined reference quad and the upper block are similar.

Abstract: An image processing method includes receiving a bitstream comprising a first encoding unit and a second encoding unit; acquiring from the bitstream a reference value for decoding of the first coding unit, a weight value for performing interpolation using the reference value to determine one or more sample values, and an index indicating one of the one or more sample values; decoding the first encoding unit using the index and a result of interpolation performed using the reference value and the weight value; and decoding the second encoding unit from the bitstream using the interpolation result used in the decoding of the first encoding unit.
