Application of the Total Least Squares Procedure to Linear View Interpolation

چکیده
It is shown that, in comparison to the results obtained from a conventional least squares approach, a total least squares solution leads to significant improvements in the geometry and appearance of images synthesised in a linear combination of views procedure. Use of the total least squares criterion is appropriate when errors on the control points are independently and identically distributed between the basis images and the target image being synthesised. When this is not be the case it is pointed out that the generalised total least squares procedure should be used. A synthetic object is used to evaluate the improvement in geometric accuracy obtained by use of the total least squares solution in comparison to a classical least squares method. Simulated and real images of laboratory test objects are similarly used to illustrate the improvement in appearance of images reconstructed by means of the total least squares procedure.

Application of Recursive Least Squares to Efficient Blunder Detection in Linear Models
In many geodetic applications a large number of observations are being measured to estimate the unknown parameters. The unbiasedness property of the estimated parameters is only ensured if there is no bias (e.g. systematic effect) or falsifying observations, which are also known as outliers. One of the most important steps towards obtaining a coherent analysis for the parameter estimation is th...

In this paper, a new method for gray-scale image and color zooming algorithm based on their local information is offered. In the proposed method, the unknown values of the new pixels on the image are computed by Moving Least Square (MLS) approximation based on both the quadratic spline and Gaussian-type weight functions. The numerical results showed that this method is more preferable to biline...
