Image Annotation Services, We Offer

bounding box annotation

Bounding Box

Annotators draw rectangular boxes around objects within an image to quickly specify their location and category, for object detection and localization by AI applications.

3D Cuboid Annotation

3D Cuboid Annotation

For enhanced spatial analysis in tech like robotics and AV, we draw 3D boxes around objects to provide depth, height and width information for specific and relevant objects.

Polygon Annotation

Polygon Annotation

For detailed object detection and segmentation, annotators use polygonal lines to trace the outlines of regions or objects to help machines recognize them like humans do.

Semantic Segmentation

Semantic Segmentation

Annotators label each pixel in an image that belongs to a specific object class, enabling understanding of content and context by AI.

Object Detection

Object Detection

We identify and locate multiple objects within an image for AI applications requiring recognition of different items in scenes, in fields like surveillance and retail.

Image Classification

Image Classification

Annotators label images based on the main object or theme, helping to categorize, and enhancing AI’s ability for content moderation and recommendation.

Polyline Annotation

Polyline Annotation

Our annotators accurately trace shapes and paths with polylines along the visible edges of objects for AI applications in path detection, mapping, etc.

Key Point Annotation

Key Point Annotation

Our annotators mark specific points on objects to define their shape or track movements. Essential for facial recognition, pose estimation and similar work.

FAQs for Image Annotation

What is the difference between image labeling and image annotation?

Image labeling and image annotation are often used interchangeably, but there’s a subtle difference. Image labeling typically involves assigning a single label or tag to an entire image, categorizing it based on its content. On the other hand, image annotation is a more detailed process, involving the addition of metadata, bounding boxes, keypoints, or segmentation masks to highlight specific objects or features within an image, providing more granular information for machine learning algorithms to interpret.

What are annotation services?

Annotation services encompass the process of adding descriptive information or labels to data, particularly in visual formats like images or videos. These annotations aid in categorizing, identifying, or analyzing the content by machines. Common tasks within annotation services include object detection, image segmentation, and classification. Such services are integral for training machine learning models across diverse domains such as autonomous vehicles, healthcare, and retail.

What are image annotation services?

Image annotation services involve the process of adding metadata or labels to images, enhancing their interpretability and usefulness for machine learning algorithms. These annotations can include bounding boxes, polygons, keypoints, or semantic segmentation masks, depending on the specific requirements of the project. Image annotation services are essential for training computer vision models in various applications such as object detection, image classification, facial recognition, and autonomous driving.

Why should I outsource image annotation?

Outsourcing image annotation offers several advantages, including cost-effectiveness, scalability, and access to specialized expertise. By leveraging the services of experienced annotation providers, businesses can streamline their workflows, accelerate project timelines, and ensure high-quality annotations that meet specific project requirements. Outsourcing also allows organizations to focus on core competencies while benefiting from the efficiency and accuracy of dedicated annotation teams.

What is the typical pricing for image annotation services?

The pricing for image annotation services varies based on factors such as complexity, volume, and annotation type. Typically, providers offer pricing models based on per-image, per-hour, or per-project rates. Prices may range from a few cents to several dollars per image, depending on the intricacy of annotations required. Some providers also offer customized pricing plans tailored to specific client needs and budget constraints.

What is the accuracy rate you guarantee?

We strive to maintain a high accuracy rate in our image annotation services, typically guaranteeing accuracy rates of 95% or higher. However, the exact accuracy rate may vary depending on the complexity of the task, annotation type, and quality of input data. We employ rigorous quality assurance measures, including human validation and quality checks, to ensure precise and reliable annotations for our clients.

How do you ensure data security and privacy?

Ensuring data security and privacy is paramount in our image annotation services. We implement robust measures such as encryption protocols, restricted access controls, and secure data transfer mechanisms to safeguard sensitive information. Additionally, our team undergoes regular training on data handling best practices and adheres to strict confidentiality agreements to maintain the integrity and confidentiality of our clients’ data throughout the annotation process.

What tools and platforms do you use for image annotation?

We leverage a variety of industry-leading tools and platforms for image annotation, tailored to suit specific project requirements. This includes popular annotation tools like LabelImg, CVAT, and VGG Image Annotator, along with custom-built annotation platforms equipped with advanced features for efficient annotation workflows. Our selection ensures accuracy, scalability, and compatibility with diverse annotation tasks across different domains and project complexities.
