In this blog, we’ll break down what image processing is, how it works, and why it’s a game-changer for businesses. Plus, we’ll explore real-world examples of how different industries are using it to boost efficiency and solve challenges. Let’s dive in!

What is an Image and What is Image Processing?

An image is a collection of pixels, the total number of pixels defines how the image will appear on the screen. The height and width of the image decide the number of pixels. For example, if the height is 400 and the width is 300 of an image, the total number of pixels in it is 12,000. 

Now when it comes to deciding the image’s color, here are a few important things to consider. Each pixel is represented by a range of values between 0 and 255 and is defined as grayscale. Here, 0 stands for black, and 255 is pure white, the other pixels are in between that range. For colored images, the three integers represent the intensity of Red, Green, and Blue colors. The image processing is performed on this image, pixel by pixel.  Image processing works by manipulating these pixels, one at a time.

On the other hand, Image processing is a computer vision technique that helps in studying, enhancing, and extracting valuable insights from digital images that are captured. By applying signal processing methods to digitally acquired images and processed as 2D signals, meaningful information can be derived. 

The five main types of image processing are:

1. Visualization:
2. Recognition;
3. Sharpening and restoration;
4. Pattern recognition;
5. Retrieval. 

If we look at the numbers, 

The digital image processing industry is expected to have a compounded growth rate of 22.8%. And might reach a CAGR of 23.3% by 2028. Such huge figures only reflect the popularity of image processing and its implementation in various industries. 

What are the various components of Image Processing:

Computer:

An image processing system can be established by using a standard computer or by using a high-performance supercomputer. If you wish to achieve more specialized tasks, you can use a custom-built computer.

Hardware for image processing:

Use a specialized digitizer and hardware with an Arithmetic Logic Unit (ALU) to carry out arithmetic and logical operations on the digital images.

Storage:

The three primary types of storage that you primarily need for digital image processing are 1. Short-term storage for immediate processing, 2. online storage for quick recall, 3. Archive storage for long-term preservation of image data. 

Camera sensors: 

Digital cameras are used to capture images using CCD and CMOS sensors. CCD is used to detect the energy emitted by the object and CMOS is a digitizer used for transforming physical sensing devices into digital form. 

Image display:

This is self-explanatory, the digital images are displayed. 

Software: 

The image processing needs specialized modules to perform the image processing function. 

Hardcopy equipment:

To initiate a hardcopy of digital images, you will need laser printers, film cameras, inkjet printers, optical and CD ROM discs, etc to record pictures. 

Networking:

A secure network is necessary for circulating the images with a specific bandwidth for image processing. 

What are the fundamental steps in digital image processing?

The following are the basic steps used for image processing:

1. Image is first either captured or retrieved from the source and necessary adjustments are initiated. 
2. The image in the test is adjusted to suitable brightness and contrast as required. 
3. Image restoration is performed using mathematical or probabilistic models to improve the quality of the image tested. 
4. Using various color modeling techniques, the digital images are processed for better visualization. 
5. The images are further segmented into small regions, often referred to as wavelets to enable efficient data compression. 
6. The captured images are compressed to a size suitable for image transmission. 
7. Further, the images are processed for segmenting into various objects. 
8. The segmented image is represented and described in a suitable form.
9. Image recognition labels the image to an object. 

How is image processing different from computer vision? 

The ultimate goal of image processing or computer vision is the same:- Making digital images interpretable. 

Image processing works on improving the quality of an image, whether by improving contrast, sharpening details, or enhancing colors. The corrected images can be used further for medical purposes like scanning or creating visually stunning graphics. 

Computer vision, on the other hand, goes beyond traditional scanning and extracts meanings from the images. It processes images to understand their behaviors, context & patterns. It is important to note here that high-quality images can give better results as compared to low-quality images. 

This is the major difference between Computer Vision and Image processing. Let us now delve into some important use cases that will bring innovation and increase efficiency across multiple industries. 

Here are a few use cases of image processing for you to explore.
