Abstract
In this dissertation, two types of B-spline curves i.e. quadratic and cubic Bsplines
are used for designing the Arabic fonts and scripts. It is also aimed to
see the applications of 8-spline curve fittings in designing the Arabic scripts,
programming has been done using MATLAB software.
Firstly, it is intended to see the aspects of smoothness, original resemblance
and segmentation of the Arabic fonts design by compari~g the usage of cubic to
the corresponding quadratic B-spline curves. This is done in order to
approximate Arabic scripts design when compared to its digitised image, using
the B-spline curves fittings method by Rosenfeld and -Johnston. Secondly, this
study also aims to find the difference when using the quadratic and cubic Bspline
curves for designing when compared to quadratic and cubic Bezier
curves. At the same time, it is also desired to see the difference when using Bspline
curve fittings for designing the Arabic scripts as compared to using the
parametric rational Bezier.
From the results obtained, it can be concluded that the quadratic B-spline
curves can be used to design Arabic fonts with narrow arcs, when compared
with using the corresponding cubic B-spline. The quadratic B-splines have to
