Data annotation services and their importance: Understand the definition of data annotation services and their importance

Data annotation service company provides annotation services for machine learning, using pre-trained models and humans to label images, text, videos or audios.

Application areas of data annotation

The data labeling task is accomplished by manually labeling and classifying objects to enable machine learning. The most common tag types include videos and images.

1. Semantic Segmentation

Semantic segmentation refers to the process of labeling each pixel in an image as a category. It is widely used in autonomous driving, robot vision and medical applications.

2. Polygon Annotation

Polygon annotation is a method of detecting irregular objects by drawing shapes and contours on image data. Annotators can mark objects they want to classify by drawing lines by placing points on the outer edges of the objects. This method can be used to identify and track objects of various shapes and sizes.

3. Bounding box

The main application of this method is to draw bounding boxes in images to facilitate object recognition. For example, in self-driving cars, bounding boxes can be used to identify entities such as vehicles, pedestrians, and traffic lights, helping the vehicle distinguish between them. Furthermore, the bounding box method can also be applied to damage detection in e-commerce, retail, and insurance companies to mark damaged areas in images. In summary, the bounding box annotation type has broad application areas for deeply identifying objects in image data.

4. 3D Cuboids

Cuboids are similar to bounding boxes, but there is one difference. The annotator specifies the length and width of the object, just like in the bounding box method. However, the 3D Cuboid method adds one more dimension, the depth of the object.

5. Lines and Splines

Annotators draw lines along boundaries, such as lane dividers on a road. It is also used to train warehouse robots to accurately line up boxes.

6. Landmark annotation

The annotator marks key points at the specified location. It is commonly used in facial recognition applications and counting applications. It helps to understand the motion trajectory of each point in the target object.

Data annotation service type?

There are 4 common data annotation resources. Businesses or individuals can rely on data annotation solutions to meet their data labeling needs.

Full-time/part-time employees, management workers, contractors, crowdsourcing platform.

The Importance of Data Annotation

Technologies such as the Internet of Things (IoT), robotics, and predictive analytics all rely on machine learning (ML) and artificial intelligence (AI). Modern machine learning methods rely on labeled data, created by companies that provide data annotation.
