Semi-Automated Segmentation of Geometric Shapes from Point Clouds
Building information models (BIM) in the civil industry are very popular nowadays. The basic information of these models is the 3D geometric model of a building structure.

Steganograhy in Images by Using Intersecting Planes [PDF]
Steganography is the art of hiding, and transmitting information using apparently innocent carrier without expose any suspicion. In this paper the proposed system is an implementation of image steganography techniques.

Optimization of starshades: focal plane versus pupil plane [PDF]
We search for the best possible transmission for an external occulter coronagraph that is dedicated to the direct observation of terrestrial exoplanets. We show that better observation conditions are obtained when the flux in the focal plane is minimized

The Plane of the Kuiper Belt [PDF]
We present a robust method for measuring the effective plane of the Kuiper belt. The derived plane has an inclination with respect to the ecliptic of 1º.86 and an ascending node of 81º.6, with a 1 σ error in pole position of the plane of 0º.37. The plane

If in a complex projective plane a point P, with coordinate vector x, corresponds to a point p*, with coordinate vector x*, under a non-singular collineation, thenx* = Axwhere A is a non-singular 3×3 matrix, the coordinates and the elements of A being complex numbers.

In this paper, we present a novel algorithm for piecewise linear regression which can learn continuous as well as discontinuous piecewise linear functions. The main idea is to repeatedly partition the data and learn a liner model in in each partition.
