lokender / UVTextureConverter

To convert atlas texuture (defined in Densepose) to normal texture (defined in SMPL), and vice versa.

UVTextureConverter

1. Install

$ pip install UVTextureConverter

2. How To Use

2.1. Quick Use

nomal texture -> atlas texture

from UVTextureConverter import Normal2Atlas
from PIL import Image
import numpy as np

normal_tex = np.array(Image.open('input/normal.jpg'))
converter = Normal2Atlas(normal_size=512, atlas_size=200)
atlas_tex = converter.convert(normal_tex)

atlas texture -> normal texture

from UVTextureConverter import Atlas2Normal
from PIL import Image
import numpy as np

im = np.array(Image.open('input/atlas.png').convert('RGB')).transpose(1, 0, 2)
atlas_tex_stack = Atlas2Normal.split_atlas_tex(im)
converter = Atlas2Normal(atlas_size=200, normal_size=512)
normal_tex = converter.convert(atlas_tex_stack)
