Image Annotation Services – Examples of Usage


Image Annotation Services Polygons

Train your computer vision models with superior, pixel accurate image recognition.

Marking objects with polygons and classification tags

Computer vision models often need in-image text labels
Our object marking solution features polygons and tagging which are ideal for training models that read and process images containing a variety of classifiable information and object details.

Our pool of Clickworkers is prepared to mark all required objects on images in a variety of ways and based on the type of object. When marking with polygons, the focus will be on a category specified by you and include the labelling of those markings with the correct designation/object description.

Semantic Segmentations

Image Annotation Services Semantic Segmentation

Does your model require pinpoint precision? If so, the training data should consist of pixel-accurate semantic segmentations.

Semantic segmentations of areas on aerial photographs

Our Image Annotation service for the pixel-based semantic segmentation of image elements is the ideal solution when a very fine granularity is required for training purposes. The semantic segmentation of images offers training data that enables pixel-accurate identification of image elements by computer vision models.

If required, the semantically segmented image elements can also be tagged or labeled according to your specifications.

Bounding Boxes

Image Annotation Services Bounding-Boxes

For training object classification and localization models

Marking of vehicles and street signs with pre-classified bounding boxes

The marking of vehicles and street signs with pre-classified bounding boxes Our Image Annotation service with bounding boxes is perfect for teaching computer vision models how to locate individual objects and persons on images. Automobile manufacturers typically use this type of training data to create infallible computer vision models to recognize all traffic situations and help to enable self-driving vehicles.

The bounding boxes can be differentiated, assigned to individual categories and tagged or labeled by our Clickworkers.

Key Points

Image Annotation Services Keyp Points

For the training computer vision models and the recognition of different shapes and stances.
The positioning of objects or persons is based on a sequence of distinctive points.

Key points for the recognition of facial characteristics

Our Image Annotation solution featuring key points is perfect for training computer vision models based on distinctive points or for recognizing and reading parts of the forms and positions of the object.

For example, images on which our Clickworkers have accurately placed key points on distinctive parts of the face can be used by computer vision models as training data for the recognition of features, expressions and emotions.

With this service, the annotation can be expressly carried out by differentially placing key points on the image based on the categories specified by you.

All-Inclusive – Image Annotation Services by clickworker

Managed Service

Our Managed Service Order solution includes project consulting, setup and handling, as well as qualifying Clickworkers for project-specific tasks.
A project manager is assigned to each client project. That requires a briefing from you which includes the data needed to complete the project and the outcomes expected – we handle the rest.

Qualified Crowdworkers

Over 2.8 million Clickworkers produce thousands of training data every day based on the needs of our clients. These individuals certify their abilities to work on certain tasks via our registration system as well as with project specific training measures.
We are able to easily identify Clickworkers who are qualified to work on your projects and can quickly authorize them to begin work on the needed tasks.

Verified Results

With our Image Annotation service, you can have all of your image annotations re-examined by a qualified representative before they are submitted to you.

Agile Technologies

With the agile, technologically advanced nature of our platform, we have the ability to develop each project to meet the specific requirements of our clients.

With our expertly developed Image Annotation tool, Clickworkers can quickly and accurately process image annotation tasks explicitly for you.

Via API, we can mutually connect our systems to allow for the transfer of your raw image files to us and the annotated images back to you.
The prompt integration of such high-quality training data to optimize your computer vision models is therefore guaranteed.

Complementary Solutions to our Image Annotation Services

Photo data sets for image recognition training

This service provides large quantities of images individually taken by our Clickworkers on their smartphones, as training material for your AI image and facial recognition systems. If required, our Clickworkers, by way of our Image Annotation Service, can also process this image material.

Photo Data Sets – More

Image categorization and tagging

With this service, you can have images, videos and audio files tagged or labeled according to your needs. Additionally, images and videos can be evaluated and classified according to quality, type, content and other related criteria (for instance, G-rated or X-rated).

Image Tagging – More

Video data sets as training data for machine learning

Utilize this service to order videos which are individually created by our worldwide crowd of Clickworkers as training data for your AI systems. Based on the training objective, our Clickworkers can create videos of their surroundings and objects, as well as human or animal motion sequences or actions.
