Cuboid Annotation – Annotating 3D Objects with 2D Data

Image Annotation with 3D cuboids

Building a 3D representation of the world from 2D images is one of the major concerns in Computer Vision. The initial step that helps to achieve this is annotating 3D objects with 2D data using Cuboids.

What is Cuboid Annotation?

Cuboid Annotation is the task of labeling objects in 2D images with cuboids. The 3D cuboids help to determine the depth of the targeted objects such as vehicles, humans, buildings, etc.

Cuboid Annotation is used for building a 3D simulated world from 2D information captured by cameras. The 3D cuboidal training data helps to train the Cuboid Detection models which aid in localizing the objects of interest in the world and in estimating their pose.

Use Cases

Autonomous Vehicle

Cuboid Annotation helps autonomous vehicles to understand the real-world environment. It mainly aids in detecting vehicle movement and its dimension for autonomous vehicles. It helps the self-driving cars to measure the distance of each obstacle from the vehicle and calculate the spacing.

Identifying Indoor Objects

You can build the model perception for detecting indoor objects using the 3D cuboid annotated images. This helps to train your Computer Vision models to have in-depth object detection capabilities. Cuboid Annotation helps to identify indoor objects like couch, table and other furniture with precision and best quality.

Training Robots

Cuboid Annotation can be effectively used for training robots that are deployed in different industries such as automotive, warehousing, etc. It helps to create better perception models that enable the robots to work continuously without the need for human interference.

Exciting Use Cases of Machine Learning

Use Cases of Machine Learning

Machine Learning has been one of the most significant technological advancements in recent times. ML is a subfield of Artificial Intelligence that gives the machines the ability to learn without the need for explicit programming by employing large datasets and training algorithms. The accelerated development of this technology has resulted in many exciting and innovative use cases which will become mainstream in the coming years.

Let’s take a look into some of the exciting use cases of Machine Learning;

Autonomous Vehicles

Self-driving cars have created a lot of curiosity and buzz in recent years. Early reports have also indicated that autonomous vehicles can reduce traffic-related fatalities and lead to a safer future for transportation. However, it will take some time for the wide-scale adoption of these autonomous vehicles.

How do these self-driving cars work?

Self-driving cars are powered by Machine Learning and Deep Learning algorithms. Unstructured data from raw images are converted to structured data by annotating objects in the images. These labeled images are then used to train the ML and DL algorithms. 

Computer Vision models are developed based on the trained ML & DL algorithms which process data points from different sensors such as radars, lidar, camera to detect the obstacles and operate the vehicles autonomously.

Moderating Content on Digital Platforms

Most of the industries have become digital leading to an exponential rise in the number of digital platforms. This has led to a situation where a heterogeneous mix of content is added to the digital platforms daily and there is a need to identify unacceptable content quickly thereby adding complexity to the review process.

Machine Learning tools such as image recognition is already being put to use by companies like Facebook, Twitter, etc., to recognize objects within images. These tools also take into account other factors such as user experience and risk involved to classify them as content to be reviewed by humans. This eliminates the large volumes of content from reviewer’s queue allowing them to see the flagged-content and take a decision on whether to publish or remove the content.

Influence Customers’ Experience in Retail

The retail companies have been gathering customer behavior data such as their age, gender, spending habits, and their preferences. But the main challenge for these companies is to extract valuable insights from the data available both offline and online to improve their business.

Machine Learning helps retailers to discover patterns in the data on which they can act upon to improve the customer buying experience and enhance their brand. Retailers can use Machine Learning models to predict which products to offer and when to give discounts from previously acquired data and provide a more personalized experience to their customers.

Efficient Healthcare

Machine Learning algorithms can be used to analyze and understand diagnoses and risk factors and give recommendations for treatment of diseases. IBM’s Watson has been deployed in various hospitals where it has proven its ability to make highly accurate recommendations for the treatment of certain cancer types. Google has also ventured into this space with a Machine Learning algorithm that helps in identifying cancerous tumors in mammograms.

Cybersecurity

Cyber-attacks are skyrocketing globally and companies are investing in huge numbers to overcome this looming threat. It is estimated that companies will spend more than $1 trillion from 2017 to 2021 in countering cyber-attacks.

Researchers worldwide are of the idea that ML can be leveraged to prevent and defend against cyber-attacks. There already exists an overabundance of big data which can be used to train the ML algorithms to improve the state of cybersecurity. Defense systems are being developed which can run for 24 hours a day and easily spot any suspicious activity and act against it based on the past data.

Machine Learning has numerous use cases in various fields. Businesses have huge amounts of data with them. By understanding core business challenges, companies can use this data to train the ML models and transform their business with intelligent systems and gain a competitive edge.

Training Data for Self Driving Cars

Training Data for Self Driving Cars

Self-driving cars also known as autonomous cars have captured the imagination of the people and mark a major change in the automotive industry. With all the major players in the automotive industry from the Tesla to Volvo, BMW, Mercedes Benz, and others investing heavily in developing self-driving cars have heated the autonomous vehicle race.

The self-driving cars which are complex machines are powered by machine learning algorithms. These algorithms help the car to process a lot of visual data similar to how a human driver does while driving. For the vehicles to identify an obstacle such as a tree or a pedestrian, it should be capable of assigning meaning to large volumes of data.

Machine Learning algorithms have to be trained with labeled data to help the self-driving cars to understand its environment. Manual labeling of objects in images is a time-consuming process. Hence Artificial Intelligence is used for image processing and labeling of data. Labeling with AI is quicker and more accurate than manual labeling.

Few things have to be considered when annotating and labeling autonomous vehicular data;

Clarity

There should be proper clarity on what objects to capture. For instance, there may be many objects at a traffic intersection. In this kind of scenario, it is best to have guidelines on what objects can qualify for labeling and capturing the right criteria for them. This helps to annotate and label the right objects and leads to efficiency and consistency.

Select the Right Toolsets

Each annotation task requires a different set of toolsets. Bounding Boxes work well for object localization and detection whereas applying text labels & drawing cuboids are required for metadata attribution. Polylines are used to outline roads and lane markings. The tools that you may use for these annotation tasks will not work for segmentation tasks. The segmentation tasks require outlining of overlapped objects and the ones that share boundaries.

Economy

The scale of data annotation need increases in the production environment. This, in turn, increases the risk of bad data. The exponential increase in training data needs at the production level has turned out to be a challenge for companies.  They have to hire enough internal resources to handle the data labeling tasks at a scale which is not feasible for a single company.

The best option is to outsource your data annotation and labeling needs to third-parties like Data Labeler who with a team of more than 1000 full-time data labelers can manage your annotation needs at scale.

At Data Labeler, we combine technology with human care to provide annotations and labeling of images and videos with pixel accuracy. Our data labelers maintain quality while processing & labeling the image data required to train and test your self-driving cars effectively.
