We present the theory behind a novel unsupervised method for discovering quasi-static objects, objects that are stationary during some interval of observation, within image sequences acquired by any number of uncalibrated cameras. For each pixel we generate a signature that encodes the pixel’s temporal structure. Using the set of temporal signatures gathered across views, we hypothesize a globa...

Figure 1. A world of hidden, small dimensions. String theories are formulated in a world of 10 or 11 spacetime dimensions. According to those theories, a point in what appears to be four-dimensional spacetime is actually a tiny multidimensional space of its own. The purple blowup hints at the complexity of those minuscule spaces; it is a projection onto three dimensions of a 6D space called a C...

We investigate the consequences of two assumptions for String ( or M) Theory, namely that: 1) all coordinates are compact and bound by the horizon of observation, 2) the “dynamics” of compactification is determined by the “second law of thermodynamics”, i.e. the principle of entropy. We discuss how this leads to a phenomenologically consistent scenario for our world, both at the elementary part...
