A pixel based texture synthesis algorithm, based off of psuedocode from Efros and Leung's 1999 paper. Given an input texture, will used Efros/Leung's patch based algorithm to synthesize a larger texture. For higher quality images, use a higher window size (I recommend at least 7). Images can grow as large as you want. (As long as you're patient enough to wait for it to render ;) )

This was tested in Octave, however, instructions should be similar if not identical for matlab.

• Load required packages - pkg load image
• Source file - source growimage.m
• Call growimage - growimage("sampleTextures/fire.JPG",5,20)
• For more information on parameters/individual functions, see function documentation.

Output filename is in format synthesized_<FILENAME>_winsize_<WINSIZE>_<OUTPUTSIZE>x<OUTPUTSIZE>. Currently input image must be in jpg format. I've included a couple 20x20 output images with varying window sizes an example in the synthesizedTextures directory.
