On the winter of 2015 I was a TA for CPSC 425, the computer vision course for undergrads at UBC. One of the assignments in the course is to implement a simplified version of the algorithm described in "Texture Synthesis by Non-parametric Sampling", by Efros and Leung from ICCV 1999 [pdf].
I thought it would help students if they could see how the algorithm works in real time, so I decided to implement the method and a visualization of it on javascript.
The live demo of the method is on http://una-dinosauria.github.io/efros-and-leung-js/. For some reason it runs way faster on Firefox compared to Chrome.
Before doing anything, go ahead and install node-js.
Now clone the project
git clone git@github.com:jltmtz/efros-and-leung-js.gitcd js
Install the dependencies
npm install -i ndarraynpm install -i raphael
Finally, export it with browserify to use the project in a web browser
npm install -g browserifybrowserify main.js -o bundle.js
And you should be ready to go!
