Annotations Processed

Bounding Box Annotation

It involves drawing a rectangular box around the object of interest and assigning a label to it. Bounding box annotation is used to train AI models for object detection, recognition, and tracking.

At TagX, we provide precise bounding box annotation services for various AI applications, including autonomous vehicles, surveillance systems, medical imaging, and more.

Polygon Annotation

Polygon annotation allows annotating a free-form shape around the object of interest, providing a more accurate representation of the object. It can be more suitable in situations where objects have complex or irregular shapes, or where multiple objects or occlusion or overlapping are present.

Whether you need polygon annotation for self-driving car technology, satellite imaging, or other computer vision applications, we can provide the precise annotations you need to train your algorithms and achieve accurate results.

Polyline Annotation

It is used to mark the boundary of an object or a region of interest that is not well-defined by a rectangular or polygonal shape. Polylines consist of a series of connected line segments that can be curved or straight, allowing for more precise and detailed annotations to highlight specific features or regions within an image.

Polyline annotation is generally used in use cases such as road marking, building footprint, or for any other object that has a distinct boundary in the image.

Semantic Segmentation

It involves dividing an image into multiple segments and assigning each segment a label based on its content, such as object classes or categories. It is preferred over other methods as it provides more accurate and detailed information about the image. This technique has practical applications in several industries like autonomous driving, medical imaging, and satellite imagery.

At TagX, we provide high-quality semantic segmentation annotation services for various AI applications, helping businesses achieve better accuracy and performance in their computer vision models.

Keypoint Annotation

This is useful for various computer vision applications, such as face recognition, pose estimation, and tracking. Keypoint annotation is preferred for these applications because it provides more accurate and detailed information about the location and orientation of specific objects or body parts in an image or video.

At TagX, we provide precise and reliable key point annotation for different AI applications. Some other applications of keypoint annotation include human activity recognition, gesture recognition, and autonomous driving.

3D Cuboid Annotation

It is a technique of creating a 3D bounding box around objects in an image or a video. It provides depth information along with the x, y, and z-axis coordinates of objects in a 3D space. 3D cuboid annotation is used for a wide range of applications, including autonomous vehicles, robotics, and augmented reality.

By accurately determining the size and position of objects in a 3D space, 3D cuboid annotation is crucial for object detection, tracking, and pose estimation in these applications. We provide high-quality 3D cuboid annotation services for different AI applications, helping our clients develop advanced computer vision models for their business needs.

Lidar Annotation

LiDAR (Light Detection and Ranging) annotation is a process of labeling 3D point cloud data captured by LiDAR sensors for AI applications such as autonomous driving, robotics, and environmental monitoring. LiDAR annotation involves identifying and labeling objects, such as cars, pedestrians, traffic signs, and road markings, in the 3D point cloud data.

We have a team of skilled annotators who have expertise in LiDAR data annotation and can deliver accurate and consistent annotations. Our LiDAR annotation services include object detection and classification, 3D object tracking, semantic segmentation, and more.

How it works?

TagX provides comprehensive data services that support every step of the Machine Learning (ML) and Artificial Intelligence (AI) data pipeline. We understand that data is the foundation of any successful ML or AI project and therefore, we work closely with our clients to provide services that cover the entire data pipeline.

Data collection

TagX gathers data from various sources such as internal systems, external APIs, and public data sets. We also provide web scraping services to extract relevant data from the web.

Data Curation

Data is curated and cleaned ensuring its relevance to the project. Preprocessing is also done extract features and engineering to make the data usable for Machine Learning and Artificial Intelligence.
