What is Image Labeling?
Image labeling is the process of annotating images with descriptive tags, categories, or boundaries to enable machine learning and artificial intelligence applications to recognize and interpret visual content accurately. Image labeling is crucial for various applications, including object detection, image classification, and image segmentation, as it provides the necessary training data that machine learning models require to learn and make predictions.How We Deliver Image Labeling Services
Step 1
Consultation and Requirements
Our process begins with a detailed consultation to understand the specific needs and goals of the client’s project. During this phase, we gather requirements related to the types of images, the types of labels required (e.g., bounding boxes, polygons, keypoints), the level of annotation detail, and the end-use of the labeled data (e.g., training machine learning models for object detection or image classification). We ensure clarity on all specifications and data security requirements.
Step 2
Team and Roles Planning
After understanding the project’s scope, we assemble a skilled team to handle the labeling tasks. The team typically includes project managers, annotators, quality assurance specialists, and technical support. Each team member is assigned specific roles based on their expertise, ensuring efficient workflow management and accountability. The project manager maintains communication with the client to ensure all milestones are met.
Step 3
Tasks and Tools Planning
We outline the tasks required for the project, breaking the work down into smaller, manageable segments. We define the specific types of labels or annotations needed for each image and identify any potential challenges. If necessary, we establish guidelines to ensure consistent labeling practices across the team. This stage also involves deciding whether to employ manual labeling, AI-assisted tools, or a combination of both.
Step 4
Software Selection
Based on the project’s requirements, we choose the most appropriate software for image labeling. This could include popular annotation platforms like Labelbox, SuperAnnotate, or custom-built tools depending on the data complexity. We ensure that the chosen software supports the required annotation formats (e.g., bounding boxes, segmentation masks, or keypoint labeling) and integrates with the client’s machine learning infrastructure if needed.
Step 5
Project Stages and Timelines
A detailed project timeline is created, outlining key milestones and deadlines for each stage of the labeling process. This timeline includes phases such as initial setup, sample labeling, full annotation, quality assurance, and final review. Regular check-ins with the client are scheduled to provide updates and ensure that all expectations are aligned throughout the process.
Step 6
Annotation Tasks Execution
The image labeling process begins with our trained annotators working to apply the required labels to the images. Depending on the project, we use a combination of manual labeling and AI-assisted tools to enhance speed and accuracy. Annotators follow strict guidelines to ensure that all labels meet the project’s specifications. In case of large datasets, we implement parallel workflows to ensure timely delivery.
Step 7
Quality and Validation Check
Quality assurance is a critical part of our process. We implement multiple quality checks, including peer reviews and automated validation processes, to ensure the accuracy and consistency of the labeled data. Any discrepancies or labeling errors are flagged and corrected, ensuring that the data is ready for high-performance machine learning tasks. We also employ inter-annotator agreement measures to maintain consistency across teams.
Step 8
Data Preparation and Formatting
After the labeling is completed and validated, we prepare the data for further use. This involves formatting the labeled images in the required structure, whether for object detection models, classification tasks, or other specific use cases. We ensure the data is converted into the necessary format, such as JSON, XML, or COCO annotations, and properly organized for easy ingestion into machine learning models.
Step 9
Prepare Results for ML Tasks
We optimize the labeled data for machine learning tasks, ensuring it meets the client’s needs for model training. This includes organizing the data into the appropriate folders, ensuring correct label hierarchy, and verifying that the labels are compatible with the client’s machine learning frameworks. Additional pre-processing steps, such as data augmentation or resizing, can also be applied to further enhance the dataset.
Step 10
Transfer Results to Customer
Once the labeled data is ready, we securely transfer it to the client via their preferred method, such as cloud storage, encrypted file transfers, or direct integration with their systems. We ensure that the transfer process is seamless and that the data is easy to access and implement. If needed, we also provide documentation or technical support to ensure smooth integration.
Step 11
Customer Feedback
After delivery, we encourage feedback from the client to ensure satisfaction with the quality and accuracy of the labeled data. If any adjustments or refinements are required, we work closely with the client to address them. We believe in building long-term relationships and continuously improving our processes based on customer feedback for future projects.Best software for Image Labeling

Types of Image Labeling Services
Bounding Box Annotation
Bounding box annotation involves drawing rectangular boxes around objects of interest within an image. It is commonly used in tasks such as object detection, allowing machine learning models to locate and classify objects within images.
Polygon Annotation
Polygon annotation is a more precise labeling method where annotators draw polygons around objects, allowing for the accurate labeling of irregularly shaped objects. This is often used for detailed object segmentation in tasks like image segmentation and autonomous driving.
Semantic Segmentation
Semantic segmentation involves labeling every pixel of an image with a class. This type of annotation is used in tasks where fine-grained detail is important, such as autonomous driving, medical imaging, and robotics, where precise object boundaries are crucial.
Instance Segmentation
Instance segmentation is a more advanced form of segmentation where each object instance within an image is labeled separately. This is used in scenarios where distinguishing between different objects of the same class is critical, such as in crowd analysis or object counting tasks.
Keypoint Annotation
Keypoint annotation involves identifying and labeling specific points on objects, such as facial landmarks (eyes, nose, mouth) or human body joints. This is widely used in facial recognition, pose estimation, and activity recognition tasks.
Polyline Annotation
Polyline annotation is used to label linear objects, such as roads, boundaries, or paths within images. It is commonly used in map creation, road detection for autonomous driving, and geographical information systems (GIS).
3D Cuboid Annotation
3D cuboid annotation involves drawing a 3D bounding box around objects to capture their three-dimensional attributes. This method is often used in autonomous driving, robotics, and augmented reality to estimate the depth and orientation of objects.
Landmark Annotation
Landmark annotation involves labeling specific points of interest within an image, often used for precise feature detection. This method is common in facial recognition, medical imaging, and structural analysis tasks where exact location points are crucial.
Image Classification
Image classification annotation involves assigning an entire image to one or more predefined categories. This is a basic yet essential form of labeling used in various tasks, such as product categorization, spam detection, and general image recognition.
Object Tracking Annotation
Object tracking involves labeling objects across multiple frames of a video or sequence of images to track their movement. This is particularly useful in video surveillance, autonomous driving, and sports analytics.
