    Our customized solutions allow you to improve overall search relevance. Our services include the evaluation of specific search results and even the entire search engine results page.

Annotation Methods

Polyline Annotation

This is usually used to annotate lanes for self-driving vehicles to define the positions of linear objects precisely without excessive noise and white spaces.

Rectangle Annotation

This is the simplest image annotation type. A large volume of rectangle annotation data can train the model to recognize the objects you need.

Key-Point Annotation

It is used to track the movement trajectories of key points for statistical models (such as foot traffic calculation models for commercial sites) as well as gesture or facial recognition models.

Polygon Annotation

This annotation features higher precision to avoid visual model deviation caused by a large amount of white space and extra noise. Common use cases include robotic grabber, medical image recognition, satellite image recognition, etc.

Semantic Segmentation

As the most precise annotation method in image annotation, it involves labeling each pixel in an image, allowing you to make full use of limited data sources.

Image Classification

This is a very important data cleaning task, especially for image recognition-based applications. It enables you to classify an image according to its visual content, paving a way for more complex annotation tasks in later stages.
