Introduction
Computer vision, which is becoming increasingly prevalent, is being adopted by a wide range of businesses, including those in the consumer electronics, retail, and manufacturing sectors.
An image is converted to a digital format during image processing, after which it is subjected to a number of processes in order to extract relevant information.
Recently, a variety of technological sectors have been greatly impacted by artificial intelligence (AI) and machine learning (ML).
Image processing is the use of computer techniques to modify digital images. Image processing has been substantially improved because of AI and ML, which allow robots to analyze and interpret images more quickly and accurately than humans.
The capacity to recognize patterns and features in big collections of photographs is a capability of AI and ML systems.
They can therefore perform tasks like object detection, classification, segmentation, and image enhancement very effectively.
In this blog, we are going to explore image processing techniques, AI and ML-based image processing, applications of AI and ML-based image processing, and more.
Without further ado, let us plunge into the realm of Image Processing!
What is Image Processing
Image processing is the process of transforming an image into digital form and performing certain operations to get some useful information from it.
The image processing system usually treats all images as 2D signals when applying certain predetermined signal processing methods.
With a variety of use cases including visualization, pattern recognition, segmentation, image information extraction, and classification, image processing can be done in two ways:
Analog image processing of physical photographs, printouts, and other hard copies of images
Digital image processing uses computer algorithms to manipulate digital images.
Main Purpose of Image Processing By leveraging image processing, valuable insights can be derived from visual data, enabling advancements in various fields and applications.
Artificial Intelligence and Machine Learning-based Image Processing:
Image processing has been significantly impacted by two rapidly developing technologies: artificial intelligence (AI) and machine learning (ML).
Artificial intelligence (AI) describes a system’s capacity to carry out operations that ordinarily require human intelligence, such as perception, thinking, and learning.
On the other hand, machine learning is a subset of AI that uses algorithms to examine data and discover patterns without being explicitly programmed.
Numerous industries, including healthcare, retail, automotive, and entertainment, use AI and ML-based image processing.
To help with diagnosis and treatment planning. In the healthcare industry, AI and ML algorithms are used to evaluate medical images like X-rays and MRIs.
Image processing algorithms can be used in retail to examine consumer behavior and offer tailored recommendations.
To improve safety systems like collision avoidance in the automotive sector, object detection and recognition algorithms using AI and ML are applied.
The analysis, manipulation, and use of images have been revolutionized by AI and ML-based image processing, creating new opportunities for creativity and innovation across a variety
Image Processing Working Mechanism
Algorithms for artificial intelligence and machine learning typically employ a workflow to learn from data. For AI systems to make highly accurate predictions, a substantial amount of high-quality data is required.
In order to properly analyze, annotate, and process photos for AI/ML, we must ensure that the images are generic and diverse.
The next step is to employ computer vision (CV) to analyze, load, transform, and modify images to produce a perfect dataset for the AI system.
An overview of the basic workflow of an image processing system
Acquisition of image: The initial step of the image processing workflow is acquiring the image using a sensor and converting it into a usable format.
Enhancement of image: The process of highlighting and drawing attention to certain intriguing details that an image has hidden.
Restoration of image: The method of improving an image’s appearance by using particular mathematical or probabilistic models.
Color image processing: There are several different methods for digital color modeling, including HSI (Hue-Saturation-Intensity), CMY (Cyan-Magenta-Yellow), and RGB (Red-Green-Blue).
Image compression/decompression: This makes it possible to change the image resolution and size without jeopardizing the quality of the images. The two primary types of image file compression used at this stage are lossy and lossless compression methods.
Morphological processing: Morphological operations are an image processing method that manipulates digital images based on their forms. The techniques are particularly suited for processing binary images since they rely on pixel values rather than numerical values. It helps to eliminate flaws in the image’s composition.
Segmentation, representation, and description: During the segmentation process, a picture is divided into segments, each of which is represented and defined in a way that allows a computer to process it further. Regional features and image quality are both covered by representation. The extraction of quantitative information that aids in differentiating one class of goods from another is the function of the description.
Recognition of image: Recognition based on a description of the object allows for the assignment of a label. Scale-invariant Feature Transform (SIFT), Speeded Up Robust Features (SURF), and PCA is some of the frequently used methods in this procedure.

Applications
Machine vision
- One or more video cameras are coupled with digital signal processing and analog-to-digital conversion. A computer or robot controller receives the picture data. Through automated analysis, this technology helps to improve automated processes.
- For instance, when tactile methods are insufficient for robotic systems to sort through a variety of forms and sizes of components, specialist machine vision image processing methods can frequently sort parts more rapidly.
- These techniques properly identify the contours or sizes of objects using extremely specialized algorithms that take into account the image’s color or greyscale values.
Pattern recognition
- Data is often categorized using previously learned information or statistical data drawn from patterns and/or their representation.
- Machine learning is then used to train the system to recognize changes in patterns after image processing is used in pattern recognition to identify the objects in an image.
- Computer-assisted diagnosis, handwriting recognition, image identification, character recognition, etc. all use pattern recognition.
Digital video processing
- The quality of a movie is determined by the number of frames or images used every minute and the standard of each frame. Aspects of video processing include noise reduction, detail enhancement, motion detection, frame rate conversion, aspect ratio conversion, and color space conversion.
- Video processing methods are used by a variety of devices, including televisions, VCRs, DVD players, and video codecs.
Transmission and encoding
- Instant access to live CCTV footage or video feeds from any location in the world is a sign of substantial improvement in image transmission and encoding technology.
- The term “progressive image transmission” refers to a method of encoding and decoding digital information that represents an image in order to present the image’s key elements, such as outlines, at low resolutions before resampling them at higher resolutions.
- An image is encoded using an electronic analog to several progressive transmission scans of the exact same image at various resolutions. The progressive image decoding produces incrementally better images whose adherence is gradually built up from sequential scan results at the receiver side.
- The outcome is an initial rough reconstruction of the image. Additionally, image compression eliminates extra data to ensure that the image processing is complete and suitable for transmission, reducing the amount of data required to describe a digital image.
Image sharpening and restoration
- In this context, “image sharpening” and “restoration” refer to the techniques applied to current camera-taken photos to improve or edit them to achieve desired effects. Included are zooming, sharpening, blurring, colorizing, recognizing edges, picture retrieval, and image recognition.
- Restoring lost resolution and reducing are the goals of restoration approaches. Image processing methods use either the frequency domain or the image domain. The simplest and most popular method for image restoration is deconvolution, which operates in the frequency domain.
- Image processing can be used to improve the quality of an image, eliminate undesirable artifacts from an image, or even produce whole new images from scratch.
- Image processing is currently one of the technologies that are developing the fastest, and it has a great deal of potential for future widespread adoption in fields like video and 3D graphics, statistical image processing, object recognition and tracking, medical diagnosis, PCB inspection, robotic guidance and control, and automatic driving in all forms of transportation.
