The main goal of this paper is to put well-established techniques for two-view motion analysis in the context of the theory of Total Least Squares and to make clear that robust and reliable motion analysis algorithms cannot be designed without a thorough statistical consideration of the consequences of errors in the input data. We focus on the non-iterative 8+n-point algorithm for estimating th...

Hartley’s eight-point algorithm has maintained an important place in computer vision, notably as a means of providing an initial value of the fundamental matrix for use in iterative estimation methods. In this paper, a novel explanation is given for the improvement in performance of the eight-point algorithm that results from using normalized data. It is first established that the normalized al...

The eight-point algorithm of Hartley occupies an important place in computer vision, notably as a means of providing an initial value of the fundamental matrix for use in iterative estimation methods. In this paper, a novel explanation is given for the improvement in performance of the eightpoint algorithm that results from using normalised data. A first step is singling out a cost function tha...

like other economic markets, housing market is comprised of supply and demand dimensions and equality of supply and demand makes the housing market balanced. the aim of this paper is to investigate the characteristics of housing market of tehran city and some deficiencies of this market with fundamental – applied methodology. the variable studied here is the saleable residential unit with minim...

We consider the self-calibration problem in the special context of a stereo head, where the two cameras are arranged on a lateral rig with coplanar optical axes, each camera being free to vary its angle of vergence. Under various constraints, we derive explicit forms for the epipolar equation, and show that a static stereo head constitutes a degenerate camera con guration for carrying out self-...

In order to grasp and manipulate an object controllably and dexterously with a multifingered hand of robot, the sensing of fingertip force is required. To these operation, for making the controlability higher and making force sensor be proof against unexpected collisions or weights, not only the sensor’s sensibility but also its stiffness are desired as high as possible. For sensing a force act...

A novel nozzle controller of spraying robot aiming toward crop-rows based on fuzzy control theory was studied in this paper to solve the shortcomings of existing nozzle control system, such as the long regulation time, the higher overshoot and so on. The new fuzzy controller mainly consists of fuzzification interface, defuzzification interface, rule-base and inference mechanism. Considering the...

Capturing information for performance modeling of the human aspect of C2 performance can be difficult and time consuming. Usually, a parametric approach is favored, but overall, technology performance is used to calibrate performance. It is difficult to determine or assess the aspects of human performance in the technologically driven C2 systems. This paper presents a novel approach using a qua...

The contribution provides the background of the model of Expansive Nondecelerative Universe, rationalizes the introduction of Vaidya metrics allowing thus to localize and quantify gravitational energy. A unifying explanation of the fundamental physical interactions is accompanied by demonstration of some consequences and predictions relating to cosmological problems.
