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 [email protected]:jltmtz/efros-and-leung-js.git
• cd js

Install the dependencies

• npm install -i ndarray
• npm install -i raphael

Finally, export it with browserify to use the project in a web browser

• npm install -g browserify
• browserify main.js -o bundle.js

And you should be ready to go!
