Image Annotation Services for Machine Learning with Pixel Perfection

Training, validating, and testing your computer vision algorithms with the well-processed training data will make or break the success of your AI project. For an AI algorithm to recognize objects like humans, each image in your dataset must be accurately and thoughtfully annotated and labeled. In general, the better your annotations and labels are, the better your machine learning models will do. Cogito, a decade-old data annotation expert, promises to be a credible ally to fulfill your training data requirements for your AI and machine learning initiatives.

What Defines Image Annotation

What Defines Image Annotation

Image annotation lies at the heart of tons of Artificial Intelligence (AI) products and applications we interact with every day. It is also one of the most important tasks in the course of training data development for Computer Vision (CV) systems. To train an AI model to recognize images, Annotators use tags, or metadata, to make data characteristics identifiable. In the subsequent step, the computer is trained to identify these characteristics when presented with new, unlabeled data based on the annotated and tagged images.

Image Annotation Techniques

Images, which are usually said to be raw datasets, can be rendered in a number of ways using different data annotation and labeling techniques before they are used as training data for AI applications. In-house annotation experts at Cogito boast unmatched expertise in a variety of image annotation methods as follows:

2D Bounding Boxes 2D Bounding Boxes

2D bounding boxes facilitate the calculation of attributes for computer vision-based models and assist in recognizing surrounding in a real-world scenario.

3D Cuboid Annotation 3D Cuboid Annotation

Cuboid annotation transforms 2D camera data into a 3D simulated environment to help machines determine the depth of objects like vehicles, humans, buildings, etc.

Key Point Annotation Key Point Annotation

Key Point annotation, also known as dot annotation, involves connecting multiple dots which helps recognize facial gestures, human poses, and sentiments.

Lines & Splines Lines & Splines

The lines and splines annotation technique consists of delineating certain parts of images with lines; it is widely used for boundary recognition in different industries.

Text Annotation Text Annotation

In text annotation, labels like appropriate names, sentiments, and intentions are added to a text according to various criteria based on the business or industrial use.

Polygons Polygons Annotation

Polygon annotation techniques is used for annotating images of irregular sizes and lengths, such as traffic and aerial images where precise annotations are needed.

Semantic Segmentation Semantic Segmentation

An image dataset is semantically segmented to locate all categories & classes. This enables recognition and understanding of an image with pixel-level accuracy.

3D Point Cloud Annotation 3D Point Cloud Annotation

The 3D point cloud annotation technique enables visual analysis of objects to better understand their dimensions and to detect and classify them more accurately.

Our Image Annotation Approach

Human-in-the-loop being a key part of our image annotation approach, Cogito primarily utilizes the human workforce for annotation, regardless of the project size and complexity. In spite of the fact that the annotation process is complex and involves so many steps, we prefer to do it manually instead of leaving it entirely to AI-powered annotation applications.

Here are the steps that we carry through the image annotation process:

  • Reviewing the dataset containing images and video;
  • Identifying relevant objects in each image, i.e., the objects of interest that need to be annotated and labeled;
  • providing predetermined labels (classes) to images depending on their characteristics;
  • Constructing bounding boxes around images for object detection and segmenting for differentiating characters/objects in the images.
