As we know that as like humans, computers can’t process the information on their own and each machine learning model mostly relies on the data it’s fed as well as accompanying annotation.

However, a large number of companies rely on machine learning for efficient workflows such as the ability to read and prediction of trends, and data-driven decision-making.

The AI annotation is also helping different industries greatly in manufacturing, software and development, Engineering, Finance, Cybersecurity, and medicines.

Let’s take a look at deep insights into AI annotation and how it changes the world of the deep machine learning process.  

What is AI assisted annotation?

AI data annotation is the process of assigning metadata of raw data set automatically to a machine or computer by categorizing, labeling, and other contextual elements, so that machine can read, learn and act upon the fed information.

For this, a huge collection of raw data is required and the large amount of data set makes the artificial intelligence (AI) machines more intelligent and they can perform exactly human-like actions.

But the problem is the machine can only act according to the set parameters for the data set and the data annotation is the primary resolution that fulfills the gap between the sample data and AI machine learning productivity.

The AI annotation accelerates the labeling by many folds as compared to the manual process.

How AI assisted annotation Work?

For making easier for AI to generate accurate annotations of the object, AI assisted labeling tools are used by the annotators to point out the edges roughly of the object of interest.

Thereafter, the labelers review, check and makes final corrections to ensure accuracy.

Benefits of AI assisted annotations

Machine learning is heavily dependent on manual annotation for a long year. The annotated data produced by the manual annotations can come in various labels such as descriptions of texture, color, and appearance.

Gathering and preparing data is one of the time-consuming steps in the life cycle of an artificial intelligence algorithm.

A deep learning model will perform poorly without a proper data set, i.e., data that is appropriate to our task and annotated.

Data annotation also frequently referred to as data labeling is for sure the hardest and longest step, which makes applications fail or succeed.

Data labeling is the process of attaching meaning to digital data.

Therefore, AI-assisted video annotation and image annotation tools can help with image and video annotation needs.

This process is manual, but usually performed or assisted by software and requires a human touch, which is very costly, time-consuming, and requires a lot of manual labour.

The AI assisted annotation is very much helpful, when it is applied in a data annotation workflow in two ways;

Pre-annotation of dataset

The automatic data annotation process cannot annotate everything and there are some exceptions and edge cases.

It is also far from perfect without any involvement of human manpower, so it requires a manual process of review and corrections as necessary.

The human annotators should be there to review, correct and complete the process of annotations.

Reduce the amount of workload

An automatic labeling model can assign a self-confidence level based on many factors such as; use cases, task difficulty, etc.

It enriches the annotated dataset and sends the lower confident annotated data for a manual review or correction process.

It has been seen in one of the image annotation experiments, auto labeling combined with human-powered review and improvements is 10% faster than the 100% manual labeling process.

That time savings increased to 40% to 50% faster as the automation learned over time.

Uses of AI assisted image annotation

There are many applications of AI assisted image annotation that proved to be beneficial, profit-making, and even have great social impact.

These include; accessibility for the disabled, security, online shopping, medical imaging, etc.

AI assisted annotation for the visually impaired

Visual impairment poses an enormous global financial burden and it is estimated to be the US $ 411 billion annual global cost of productivity losses.

According to a report by WHO in October 2022, at least 2.2 billion people are suffering from vision impairments.

People with visual impairment face an enormous number of challenges in daily life. One of the biggest challenges is mobility and orientation i.e., the ability to walk safely and accurately from one place to another place.

Public transportation, such as buses, is the main tool for individuals to navigate and get to where they want. 

Thus, people living with visual impairments can get benefit greatly from AI assisted image annotation.

Smartphones or other gadgets with cameras can be outfitted with Automatic image annotation to recognize objects and read or describe them out loud to the users.

Family members, friends, and text can also be recognized, making it easier for people with disabilities to live independent lives.

AI assisted annotation in Security

Nowadays, the demand for real-time AI camera-based object detection is greatly increased in both industries as well as public spheres.

More importantly, the public spheres become increasingly susceptible to crimes, illegal activities, and violence.

Thus, implementing artificial intelligence (AI) in surveillance and security can provide a reliable protective blanket to ease turbulence.

The AI assisted annotations of images by using computer vision can assists security personnel and law enforcement to get early warning systems to mitigate rising concerns of chaos and commotion in public.

Artificial intelligence allows security cameras to provide round-the-clock surveillance and makes much more secure and safe lives of people.

Thus, high-quality image annotations are required for creating such high-tech video equipment and their integration into the surveillance system.

The data from images and videos captured from similar cameras as well as their proper labeling are used to develop such artificial intelligence cameras.

Types of AI assisted annotations of images used in security and surveillance systems

There are various types of image annotations used for AI in security and surveillance systems;

Recently Google launched its new product medical imaging suite, which comprises of AI-assisted annotation environment with the help of NVIDIA and the MONAI open framework.

AI-assisted annotation has emerged to speed up annotation workflows and increase productivity in the field of medical imaging.

NVIDIA AI assisted annotation for medical imaging

The identification and analysis of specific features in medical images slow down due to the growing volume of clinical data in medical imaging.

This reduces the speed of data annotation as well as enhances the cost and slows down the diagnosis process.

Sometimes due to the unavailability of well-trained medical personnel, the patients get suffered from the improper diagnoses.

Therefore, the applications of annotation tools in medical imaging greatly help radiologists to annotate organs as well as abnormalities.

These applications comprise software tools to isolate the organs of interest from the rest of the dataset and typically operate on 2D slices.

A radiologist takes a single 2D image slice from a patient’s scan and marks annotation boundaries and corrections as needed.

This manual process repeats for the next slice in which the organ of interest is annotated and corrected again.

Some applications also support 3D tools for annotation with region-growing techniques that perform fairly well with certain organs but poorly on other organs.

As these workflows are completely manual, the annotation process takes a lot of time.

However, NVIDIA AI assisted annotation enables deep learning-based applications. It provides the tools which speed up the annotation process, as a result, it greatly helps radiologists in terms of saving time, and increasing productivity.
