What Is Image Processing In Computer Vision?
A research field called computer vision seeks to use cameras to create models for comprehending our three-dimensional surroundings. Image processing is also the broad category of methods used to directly extract useful information from images or prepare them for the best possible analysis. As a result of that, computer vision and image processing are two closely linked topics.
In this article, we will discuss what image processing is, where image processing is used, and the differences between image processing and computer vision.
What Is Image Processing?
An image can be improved or have essential information extracted using image processing. It is a form of signal processing in which a picture serves as the input, and the outcome could be a different image, features, or properties of the input image. Technology now increasingly includes image processing, and the computer and engineering science disciplines use it as their primary study topic.
Image processing consists of three steps:
- Importing the picture using software for image capture;
- Examining and modifying the picture;
- A changed image or a report based on image analysis may be the output of the process.
The two types of techniques applied are analog and digital image processing. Printouts and images on hard copies can be processed using analog image processing. When applying these visual techniques, image analysts employ several interpretational fundamentals. Digital image processing tools are used to enable computer-based digital image editing. When adopting digital technology, all sorts of data must go through three primary stages: pre-processing, enhancement and display, and information extraction.
Where Is Image Processing Used?
Now we will look at the areas in which image processing is used.
Image Retouching, Vignetting, and Resolution adjustment
We frequently wish we could improve on old pictures. And that is now achievable. This includes zooming, sharpening, edge detection, and high dynamic range adjustments, and these actions all contribute to improving the image. Most editing programs and image repair algorithms can readily accomplish these tasks.
Filters on Social Media and Editing Apps
These days, filters are available on most editing and social media apps. The image looks more aesthetically attractive, thanks to filters. Filters are typically a collection of operations that alter an image's colors and other elements to give it a unique appearance—an intriguing use of image processing filters.
PET scanning, X-ray imaging, medical CT scanning, UV imaging, cancer cell image processing, and many other tasks involving image processing are used in the medical sector. Diagnostics have become much better thanks to the development of image processing in medical technology.
Computer / Machine Vision:
Computer Vision is one of the most fascinating and practical uses of image processing. Computer vision is used to enable a computer to view, recognize objects, and interpret the entire environment. Self-driving cars, drones, and other devices are significant applications of computer vision. Obstacle detection, path recognition, and environmental comprehension are all made more accessible by CV.
Pattern recognition is a component of image processing that uses AI and machine learning. To discover patterns and other characteristics in photos, image processing is utilized. Handwriting analysis, image identification, computer-assisted medical diagnosis, and many other applications use pattern recognition.
The video consists primarily of rapidly changing pictures. Video processing employs several image processing techniques, and video processing examples include noise reduction, image stabilization, frame rate conversion, detail improvement, and many other methods.
What Is the Difference Between Computer Vision And Image Processing
- The field of artificial intelligence, known as computer vision, aims to imitate the complexity of the human visual system while empowering computers to comprehend the digital world. It makes it possible for computers to perceive, analyze, and process images like humans do. Contrarily, image processing entails altering images to draw out valuable information. Image processing is known as the art and science of information extraction from photographs.
- Image processing, as its names imply, is used in processing images, so both the input and output are, in essence, visual representations of the processed data. It is a catch-all phrase for various processes that examine images and change one feature of an idea into another. In contrast, the goal of computer vision is to enable machines to recognize patterns and extrapolate meaningful information from digital photos, videos, and other visual inputs to improve our understanding of the visible world.
- Quality of an image, filtering, sharpening, and restoration are some of the earliest and most widely used image processing applications. Nowadays, most social networking apps and image and video editing programs include filters to improve images. Medical uses, pattern recognition, video processing, object tracking, machine vision, and other contemporary uses are examples. Defect detection, face detection, object detection, image categorization, movement analysis, object tracking, cell classification, and other real-world uses for computer vision are just a few.
Why Is Image Processing Important For Computer Vision?
Now that we've debated the differences, let's look at how these two can work together and strengthen one another. Implementations like damage detection, object tracking, and self-driving cars have entered a new era thanks to intelligent algorithms. Where do the two overlap, then?
One of the reliable analytic techniques is image processing, which is a subset of machine vision. This is how computer vision functions, and it comprises several parts, including cameras, lighting equipment, and digital processing methods.
Thus, processing software is a component of the whole system that helps the solution get the image ready for additional analysis. For better visual interpretation, image editing, and restoration techniques, for instance, assist in removing apparent deterioration from digital copies. Machine learning techniques are necessary for image processing and computer vision.

Computer vision includes image processing as a subset. Computer vision systems use image processing methods to simulate vision on a human scale. For instance, image processing might be used when the aim is to improve the image for usage in the future. But if, it is referred to as computer vision if the objective is to recognize objects, such as a flaw in an automatic driving system.
