Computer Graphics and image processing Mathematical Background
Numerical Background
1.1 Introduction
The instructed material in this course draws upon a numerical foundation in direct polynomial math.
We momentarily update a portion of the fundamentals here, prior to starting the course material in Chapter 2.
1.2 Points, Vectors, and Notation
Quite a bit of Computer Graphics includes conversation of focuses in 2D or 3D. Normally we compose such
focuses as Cartesian Coordinates for example p = [x, y]
T or q = [x, y, z]
T
. Point organizes are
accordingly vector amounts, instead of a solitary number for example 3 which we call a scalar
amount. In these notes, we compose vectors in striking and underlined once. Grids are composed
in striking, twofold underlined.
The superscript [...]
T indicates rendering of a vector, so focuses p and q are segmented vectors
(organizes stacked on top of each other in an upward direction). This is the show utilized by most
scientists with a Computer Vision foundation, and is the show utilized all through this
course. On the other hand, numerous Computer Graphics specialists use line vectors to address
focuses. Consequently, you will discover line vectors in numerous Graphics course readings including Foley
et al, one of the course messages. Remember that you can change over conditions between the
two structures utilizing interpretation. Assume we have a 2 × 2 framework M following up on the 2D point
addressed by segment vector p. We would compose this as Mp.
On the off chance that p was rendered into a column vector p
′ = p
T
, we could compose the above change
p
′MT
. So to change over between the structures (for example from line to segment structure when perusing the
course-messages), recollect that:
Mp = (p
TMT
)
T
(1.1)
For an update on lattice rendering kindly see subsection 1.7.5.
1.3 Basic Vector Algebra
Similarly, as we can perform essential tasks like expansion, duplication, and so forth on scalar
values, so we can sum up such activities to vectors. Figure 1.1 sums up a portion of these
tasks in diagrammatic structure.Numerical Background
