Computer vision tools and techniques are highly dependent on linear algebraic operations. We will use see an explanation of basic to advanced operations that are required in developing CV applications.
Linear algebra
Vectors
In a 2D plane, vectors are denoted as a point 
.
In this case, the magnitude of p is denoted as 
and is given by the following:
In Python, a vector is denoted by a one-dimensional array, as follows:
p = [1, 2, 3]
Here, the common properties required are length of the vector and magnitude of the vector, which is given as follows:
print(len(p))
>>> 3
Common vector operations are as follows:
- Addition
- Subtraction
- Vector multiplication
- Vector norm
- Orthogonality
