Adding seam carving atlas synthesis

[josuperstar]

We are able to have a vertex weight V_s and a fading Tau (0-1) per patch. We should be able to select a texture exemplar for the synthesis according to the Tau among a set of seam carved texture.

We need to have two more process:

1. Generate seam carving animation
2. Patch texture exemplar must be in function of the fading (0 to 1)

To be able to convert the fading factor from 0 to 1 to an integer representing a frame in an animated texture, we could start creating an animation with 100 frames.

The first process can be done using the existing python script. The second process must be done with a new blending class, were we pre-load the 100 frame of the texture exemplar.

We need to do a transformation to the origin before doing the scaling of the patch.

[josuperstar]

Since seam carving is removing lines from the whole texture examplar, if we use sub space of the texture examplar to create patch, as in Yu 2011, we can have a sliding effect inside the patch.

[josuperstar]

We need to use the whole texture examplar centered in the middle of the patch to avoid sliding effect.
