Verilog HDL: Magnitude
For a vector (a,b), the magnitude representation is the following:
A common approach to implementing these arithmetic functions is to use the Coordinate rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.
ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points.
Ordinary usage:
[R, T] = icp(model,data)
INPUT:
model - matrix with model points,
data - matrix with data points,
OUTPUT:
R - rotation matrix and
T - translation vector accordingly
so
newdata = R*data + T .
newdata are transformed data points to fit model

face detection
Face detection can be regarded as a more general case of face localization In face localization, the task is to find the locations and sizes of a known number of faces (usually one). In face detection, one does not have this additional information.
Early face-detection algorithms focused on the detection of frontal human faces, whereas newer algorithms attempt to solve the more general and difficult problem of multi-view face detection. That is, the detection of faces that are either rotated along the axis from the face to the observer (in-plane rotation), or rotated along the vertical or left-right axis (out-of-plane rotation),or both.
This paper presents a new type of electromagnetic damper with rotating inertial mass that has been devel
oped to control the vibrations of structures subjected to earthquakes. The electromagnetic inertial mass
damper (EIMD) consists of a ball screw that converts axial oscillation of the rod end into rotational motion
of the internal flflywheel and an electric generator that is turned by the rotation of the inner rod. The EIMD is
able to generate a large inertial force created by the rotating flflywheel and a variable damping force devel
oped by the electric generator. Device performance tests of reduced-scale and full-scale EIMDs were under
taken to verify the basic characteristics of the damper and the validity of the derived theoretical formulae.
Shaking table tests of a three-story structure with EIMDs and earthquake response analyses of a building
with EIMDs were conducted to demonstrate the seismic response control performance of the EIMD. The
EIMD is able to reduce story drifts as well as accelerations and surpasses conventional types of dampers
in reducing acceleration responses.
