Texture synthesis in Torch

texture-synthesis

This is a Torch implementation of a texture-synthesis algorithm very similar to [1].

Given an input texture patch, the algorithm generates a larger version of the same texture. Here's an example:

You can see more examples in the example gallery.

Usage

Texture synthesis is implemented in the script synthesis.lua. The following command line options are available:

• -source: Path to the source image.
• -output_file: Path where the output should be written.
• -height: Height of the output file, in pixels.
• -width: Width of the output file, in pixels.
• -k: Kernel size; must be an odd integer.
• -gpu: Which GPU to use. Setting gpu >= 0 will run in GPU mode, and setting gpu < 0 will run in CPU-only mode.

You can see examples using different source images and kernel sizes in the example gallery.
