Here in the UK, if you’re looking for the services of a data annotation expert, it can definitely be a London-based entity, by the name of “Aya Data” that has gathered huge experience in this domain. They’re subject matter experts (SME), when it comes to precise data labelling & annotation services for local, as well as global clientele. But, first let’s understand what data annotation means, and how it is effectively used by almost a majority of ‘present-day’ organizations and companies to their benefit.
What is Data Annotation?
It is the complex process of labelling unstructured data & information to train computer vision & machine learning models in an efficient way. The raw data that you see in your everyday life can be in the form of text, images, videos and audio files. Data is correctly and accurately labelled to help machine models identify, segregate and understand different objects, semantics and their meaning. It can also perform functions like speech recognition or driving auto-driven or self-driven vehicles. The 3 main types of annotation services are Image Annotation, Video Annotation & Text Annotation.
Various Methods of Data Annotation Services
Let’s understand the different methods through which data annotation services are performed, and how computers are trained for carrying out proper identification of still images, moving objects, videos and text; thereby generating the real value or meaning of these unstructured data.
Bounding Boxes – It is object detection by making frames through 2D detection technology or method. Here, data is labelled with the help of bounding boxes around the object. This helps in proper identification and machine learning. Here, 2D & 3D bounding box annotation tools are used, depending on quality and size of data. It also helps in training autonomous vehicles to recognize stationary or moving objects with proper object tagging & image classification.
Polygon Annotation – Through this advanced method, you can identify precision objects by increasing the Artificial Intelligence (AI) accuracy. This helps in annotating irregular, raw or coarse objects that are in asymmetrical dimensions. It also helps in capturing large images like aerial photography for highly precise annotation.
Image Segmentation – In this method or technique, image elements are categorized, Pixel-By-Pixel, which offers a clear identification. It is taking raw data like 2D images, as an input method. thereby converting them into a blur object, with precise areas that are highlighted.
LIDAR Annotation – It is through Laser precision and high clarity, machine learning or computer vision models are trained with raw unstructured data.
Semantic & Content Analysis – Here machines are trained to understand the real intent of human language and the semantics associated with it. This is how computers are able to perform certain tasks.
Landmark Annotation – In this method, a sequence of points are plotted accurately, in order to identify the actual shape and contours of natural objects like facial features, emotions & expressions.
3D Cuboid Annotation – Here, the objects are captured in 3D cuboid images for getting the most accurate & precise dimension view, and thereafter build an increasingly comprehensive training model with detailed information.
Data Annotation with Pixel Perfection
Whether it is text annotation, video annotation, image annotation or audio annotation, it has to be conducted in a ‘pixel-perfect’ manner. This allows your organization’s computers to classify images and detect objects in miscellaneous categories. An expert in data annotation service makes data labelling possible for companies in all domains & business verticals to develop Artificial Intelligence based functional models, without any technical errors and flaws. It is a cost-effective alternative for training machine learning modules of Artificial Intelligence companies.
So, this is how data annotation & data labeling services are used by a majority of organizations, the world over. Be it in the area of healthcare, agriculture, self-driving vehicles, retail stores, robotics, GPS & Satellites, finance, IT services, etc. all are benefitting through precise data annotation, as delivered by data specialists.
