STRUCTURE PRESERVING IMAGE INTERPOLATION VIA ADAPTIVE 2D AUTOREGRESSIVE MODELING Xiangjun Zhang and Xiaolin Wu Department of Electrical & Computer Engineering‚ McMaster University Hamilton‚ ON‚ Canada L8S 4K1; zhangxj@grads.ece.mcmaster.ca/xwu@ece.mcmaster.ca ABSTRACT The performance of image interpolation depends on an image model that can adapt to nonstationary statistics of natural images when estimating the missing pixels. However‚ the construction of such an adaptive model needs the knowledge

2.2.1 Forest Road Constructions and Natural Environment Forest Road Constructions have serious effects to the natural environment. These effects can be direct or indirect. Road technical works that include big cut up and fill up constructions change the natural landscape and the ecological balance. Natural landscape is aesthetically downgraded. The vegetation (e.g. trees‚ bushes) that was previously located on the roadway is removed therefore forest environmental and social advantages (oxygen production

FERGUSON AND BEZIER CURVES Palash Luthra Sachin Maheshwari Netaji Subhas Institute of Technology New Delhi-110078 India 1. CURVES-DEFINITION 2. NEED OF CURVES March 2013 A line or outline that gradually deviates from being straight for some or all of its length. Curves play a very significant role in CAD modeling‚ especially‚ for generating a wireframe model‚ which is the simplest form for representing a model. We can display an object on a monitor screen in three different computer-model forms:

to solve in order to find the cubic spline passing through the three points (0‚ 1)‚ (0.5‚ 2) and (1‚ 4). Plot the resulting spline (you may use the file plotspline.m). 5. What happens to the condition number of the matrix S used in cubic spline interpolation as the size n becomes large (you may use the file splinemat.m)? 6. A parabolic runout spline is the interpolating function you get by changing the condition f ′′ (x1 ) = f ′′ (xn ) = 0 to the condition that p1 (x) and pn−1 (x) should be quadratic
