Introduction to Image processing
To create a digital image we need to convert the continuous sensed data into a digital form , this
involves two processes : Sampling and quantization
Sample : the 2D space on a regular grid
Digitizing : the coordinate valu
Digital Image Definitions
A digital image a[m,n] described in a 2D discrete space is derived from an analog
image a(x,y) in a 2D continuous space through a sampling process that is frequently
referred to as digitization.

that calculates its factorial. The main function will print the result.

Binary Tree Theorems 1
Here are two important types of binary trees. Note that the definitions, while similar,
are logically independent.

Binary Search Trees (BST)
1. Hierarchical data structure with a single reference to root node
2. Each node has at most two child nodes (a left and
a right child)
3. Nodes are organized by the Binary Search property:
Every node is ordered by some key data

EXAMPLE 1: Prove that
n(n + 1)
2
1 + 2 + 3 + . + n =
(1.1)
for any integer n 1.
Proof:
STEP 1: For n=1 (1.1) is true, since
1=
1(1 + 1)
.
2
STEP 2: Suppose (1.1) is true for some n = k 1, that is
1 + 2 + 3 + . + k =
k (k + 1)
