computer vision explained in five
minutes
hi everybody if you're looking to start
your career as a computer vision
professional from scratch
then you are in the right place computer
vision or cv
is a branch of computer science that
empowers machines to see
recognize and process images just like
humans
computer vision is in fact a
multi-disciplinary field
it could be called a subfield of
artificial intelligence ai
and machine learning ml computer vision
makes use of general learning algorithms
and may require the use of specialized
methods
this diagram shows the relationship
between artificial intelligence and
computer vision
being a multi-disciplinary field of
study can seem messy for a beginner
the reason for this is some techniques
are borrowed and reused from an
assortment of engineering and computer
science fields
understanding the content of digital
images is the main objective of computer
vision
this might seem easy but it's not so
because computers are not the same as
humans
they don't have the gift of vision and
perception while seeing and perceiving
the world around them comes naturally to
humans
that's not the case with computers
[Music]
how do computer vision algorithms work
the computer vision algorithms used
today
are based on pattern recognition they
typically rely
on convolutional neural networks or cnns
computers are first trained on an
enormous amount of visual data
in this step computers process images
and label the various objects on them
they also find patterns in those objects
for instance if we send a million images
of cats
the computer will first analyze all the
images
it will then identify patterns that are
similar to all cats
and at the end of the whole process
create a model cat
as a result the computer can accurately
detect whether or not a particular image
is a cat each time we send it pictures
the unprecedented growth of computer
vision images dominate the internet
today
they are everywhere social media
ecommerce stores
travel sites and more but along with an
enormous amount of visual data
over 3 billion images are shared every
day we also have easy access to the

making today's systems more accurate
than humans
it's an accepted fact that computers
react much more quickly than humans to
visual inputs
the applications of computer vision the
earliest experiments in computer vision
began in the 1950s
computer vision was however first put to
commercial use only in the 1970s
to differentiate typed text from
handwritten text but today
computer vision is a reliable and mature
technology that generates huge cost
savings and saves time
from defect detection to intruder
detection mask detection to tumor
detection
crop monitoring to plant monitoring

most popular computer vision
applications include
object classification recognizing the
broad category of an
object in a photograph object
identification
identifying the type of object in a
photograph object detection
detecting the location of an object in a
photograph
object verification verifying the
presence of an object in a photograph
object landmark detection detecting the
key points for an object in a photograph
object segmentation segmenting the
pixels that belong to an object in an
image
and object recognition recognizing the
objects in a photograph and pinpointing
their location
