What is an Image ? A visual representation  of an object  such as 2-D pictures, photographs. Each image has its own story to tell the critical information  or any other info. And the operations or methods that we perform  to get useful information from the image are called Image Processing . And using this information to train the models in Machine Learning .

Technically, It is used to transform an image into a digital form and apply some Algorithms to extract some useful information from the image. Generally, it is a type of signal processing where the input is the image and after operating, the output may also the image or any features/characteristics generated from the image.

Image Processing is the part of <a dir="ltr" href="https://en.wikipedia.org/wiki/Computer_vision" rel="noreferrer noopener">Computer Vision </a> that also plays important role in real-life examples, such as Face Detection , Medical Science , Robotics , Self Drive , Mood Detection , and many more… which can be further processed by Machine Learning algorithms … Okay, we will discuss this later. But before this, we need to understand more about Image Processing.

In this article, we will cover more information so let’s start.

#  What are the types of Image Processing?

There are two types of Image Processing, let’s discuss one by one.

Analog Image Processing is a technique that can be used for hard copies such as prints , photographs , xerox , etc. In other words, television is also an example of analog, we saw the pictures which can be controlled by an electric signal or waves, and the data which represented as analog wave formats can be named Analog Image Processing.

On the Other hand, Digital Image Processing is the one which we can operate digitally by using Computers, Laptops. The input for this technique is a digital image , and the process performed on that image using some algorithms results in an image as output. Many applications are there that help us to transform the image, for example, Photoshop , After Effects , Photo Editor , and many more.

#  What are the Steps in Image Processing?

Ok, let’s understand this by taking the example of Photoshop

The first step of image processing is to import the image in photoshop that we have already discussed (takes an image as input).

After importing, we do Analysis and Manipulating the data, which means the process that includes enhancement of an image, for example, using filters, compression, scaling, blur reduction, etc.

Output, Result of Analysis that is now ready to use.

Earlier we have discussed brief of image processing, then their types, and the process steps that image processing follows. Now in this block, we will see with the help of an example that how it works.

Digital image processing plays an important role to enhance the image at a super level using such tools or programming languages.

<ul><li>Capture the real-world object : Captured image using the camera, which is the input to start the Digital IP process. </li> </ul>

<ul><li>Sent to a digital system : The captured image has been sent to a digital system to enhance and perform operations on it. Mainly focus on the enhancement of the image such as reduce noise, use filters, contrast, and so on. </li> </ul>

<ul><li>Final output : After performing some operations on the digital image, we have generated the output with a more enhanced, clear, attractive, and quality image. That’s the power of image processing, which we will use further to get the crucial information. </li> </ul>

#  How it is related to Machine Learning?

Now the most common question nowadays that, how Image processing connected with Machine learning? The simple answer is that Image processing is used toextract the features (includes enhancement, compression, restoration, etc.) and use this information or features to train the models done by Machine Learning . And the whole process or the combination is known as Computer Vision .

Image processing problem =&gt; Optimisation problem

Machine learning =&gt; Effective tool to solve Optimisation problem.

Few examples are, Face Expression, Face Identification, Disease detection from Medical images, and many more, so we can say they are linked  together!!

It would be possible with hte help of Machine learning, so it is everywhere from small to large applications in the world, you just need to identify. We will discuss this more in our next article with more Machine Learning concepts.

#  Applications of Image Processing in Real World?

Many real-world examples play a vital role in daily life. It includes

I have also worked on one of the projects earlier named Lung Cancer Detection, where I have been using CT scan images to find out the tumor  in the lungs by using Image Processing &amp; Machine learning algorithms. The basic structure of this application is:

Basic Structure to analyze the medical images.

Take the CT image as the input, apply algorithms to enhance the targeted area using edge removal, Support Vector Machine algorithm to segment the part of the lung, where we need further process.

So, after performing the feature extraction, we need to apply some Machine learning algorithms to solve the observed problem by using feature, trained or existing models to get the final analysis report.

Nowadays, we are using these types of features in our mobile phones , laptops , cameras and so on, to secure critical or personal information from others.

This sector has seen maximum growth in the past years. But nothing can beat this industry to show the innovations. Yes, we are talking about Self Driving cars .
