Tips

• upload images in the [imgs] folder, then specify in [main.py] the path to the desired source, target and mask images.
• masks can be created using GIMP as shown below.
• some outputs are already saved in the [output] folder. To save others, enable the corresponding code section in [main.py].
• in [poisson_blending] comment/decomment intermediate lines for gradients visualization if desired.

How to create a mask for seamless cloning

• Open source image and create new level

• Draw contour with pencil

• Fill shape and set image level as invisible

• Export as png

How to prepare images and masks for texture transfer

Target image:

Source image from where to extract the texture:

• Open the target image with GIMP
• Create a mask (see the section above) of the area where to paste the new texture

• Set the target image invisible and export the mask as png

• Open the source image and the mask in the same project, with the mask level above

• Move and resize the source image so that the area with the desired texture is visible through the mask

• Make the mask invisible and export the new source image; it will now have the same dimensions of the target image and will be already aligned:
