Tasks that require annotated data

Various tasks in fields such as machine learning, computer vision, and artificial intelligence require annotated data for training and evaluation purposes. Annotation involves labeling data with relevant information, such as identifying & recognition objects on images or pictures.

  • Object detection with 2Captcha API

    Label images for object detection

    Labeling images for object detection involves identifying and marking specific objects within images with bounding boxes or masks. This process is essential for training object detection models to accurately recognize and locate objects of interest within images.

  • Image classification with 2Captcha API

    Image classification

    Image classification involves labeling images with predefined tags or labels using supervised deep learning algorithms. Annotations for this task can be simple text labels, class numbers, or one-hot encodings. These annotations are converted into suitable formats before being used in loss functions during training.

What is image annotation?

Example of image annotation

Image annotation refers to the process of labeling images within a given dataset to facilitate the training of machine learning models.

Once manual annotation is finalized, the labeled images are fed into a machine learning or deep learning model, which replicates the annotations without requiring human intervention.

Image annotation establishes the benchmarks that the model endeavors to replicate; consequently, any inaccuracies in the labels are also reproduced. Hence, accurate image annotation forms the cornerstone for training neural networks, rendering annotation one of the pivotal tasks in the realm of computer vision.

Image annotation workflow

The process where in a model autonomously labels images is commonly known as model-assisted labeling.

Image annotations can be conducted manually or through the utilization of automated annotation tools.

Automated annotation tools typically encompass pre-trained algorithms capable of annotating images with a certain level of precision. Their annotations prove invaluable for intricate annotation tasks such as generating segment masks, which are time-intensive to create.

Image annotation types

In such scenarios, auto-annotation tools aid manual annotation by furnishing a starting point from which further annotation can proceed.

Moreover, manual annotation is often supplemented by tools that facilitate the recording of key points to simplify data labeling and data storage.
