Python Texture Transfer

This is a python implementation of Texture transfer as presented in Siggraph 2001. 
The implementation icludes some optimizations of the original method as suggested in later publications. 

- Requirements:
Scipy (and numpy)
PIL

I've included a cherrypy server that runs the texture transfer with a simple interface. The server requires CherryPy installed also.


- Usage:

Make a TextureTransferTool object and then use .start()

parameters:
source - The image used as texture
target - The image to texture
blockW - Block width (block is the size of a patch from the source image)
blockH - Block width
num_of_iterations - number of iterations. as the iteration incease the block size is reduced and more weight is give to the texture matching over the target matching
overlap_x_frac - the overlap between blocks, horizontal (recommeneded value is around 0.3)
overlap_y_frac - the overlap between blocks, vertical (recommeneded value is around 0.3)
block_reduciton_factor - the size decresement (between 0-1) of the block size after each iteration
amount_to_probe_frac - the amount of attempted blocks to try and match to the input block

sample usage:

t = texture_transfer.TextureTransferTool(source, target, 64, 64, 3, 0.3, 0.3, 0.8, 0.005, 0)
t.start(output)
