This paper re-examines the problem of distributed consensus with the aim of improving performance and understanding.

Documents the process to transform a picture of a warped text (e.g.: pictures of pages from a book) and produce a result where lines are parallel and horizontal.

The goal we set for our computer vision experiment was to detect the color of the dominant object of a picture. Searching by color is a common occurence when it comes to e-commerce websites, and while the nature of the object is usually clear in the description, its color is often more of a problem.

Visual Cryptography uses two transparent images. One image contains random pixels and the other image contains the secret information. It is impossible to retrieve the secret information from one of the images. Both transparent images or layers are required to reveal the information. The easiest way to implement Visual Cryptography is to print the two layers onto a transparent sheet.
