Image Annotation for Computer Vision
Computer vision image annotation involves adding labels to digital images in order to train computer vision algorithms. The process involves labeling objects in images, identifying features in the images, and outlining the boundaries of objects. Image labeling can be used for a variety of tasks, like detecting objects, segmenting pictures, and categorizing them.

Image Annotation Process
It typically takes several steps to annotate an image. We begin by collecting the images that will be annotated and organizing them into folders. Each image is labeled according to the activities and objects it contains. The step can be completed manually or automatically using AI-enabled image annotation tools. The labels are then verified for accuracy. Finally, the data is uploaded to a database for use in machine learning models.
Our Image Annotation Process Involves:
2D Bounding Boxes
2D bounding boxes define the boundaries of objects in two-dimensional space using graphic representations. The boxes are usually used in computer vision and machine learning applications to delineate the area of interest for objects.
In bounding boxes, the origin and the extent of the box are usually represented as four-sided polygons. With 2D bounding boxes, attributes can be calculated for computer vision-based models and surroundings can be recognized in real-world situations more easily.
3D Cuboid Annotation
The 3D cuboid image annotation can be used to detect and recognize 3D objects in images. Using Cuboids annotation, machines can determine the depth of objects such as vehicles, people, buildings, and other objects.
Thus, a machine can recognize, classify, and recognize objects in 3D space with 3D cuboid annotation, allowing for more accurate and efficient recognition of objects. Computer vision applications like autonomous driving, robotics, medical imaging, and augmented reality use this technique.
Key Point Annotation
Known also as dot annotation, The key point image data annotation recognizes facial gestures, human poses, expressions, emotions, body language, and sentiments through the connection of multiple dots.
It is the process of adding additional information or context to a text or other type of media through annotations. It’s an annotation type where a specific point on a text or media is highlighted and a comment or explanation is added to draw attention to what the image symbolizes.
Lines & Splines
Annotating images with lines and splines is one of the most common ways to visualize data. The lines in this form of image annotation depict a single value or trend in the data by connecting two points on the image. Lines and splines are similar, but splines are curved and can represent time-dependent changes in data.
A line or spline annotation is commonly used to aid the viewer in understanding data visualizations, such as charts and graphs. Medical imaging can also be utilized for identifying areas of interest or anomalies.
Text Annotation
In the text annotation, certain features and characteristics of a text are identified by labeling and analyzing it. The text structure is often analyzed, themes are identified, errors are detected, and important passages are marked out.
As part of text annotations, appropriate tags, such as names, sentiments, and intentions, are added to a text in accordance with various criteria based on the business or industrial use of the text. There are a variety of applications for text annotation, including literary studies, linguistics, and natural language processing.
Polygons Annotation
A polygon annotation is a type of image annotation used to mark and draw shapes on a digital image. The technique allows marking objects within an image based on their position and orientation.
It involves labeling images of irregular dimensions, or uneven lengths and breaths, such as traffic and aerial images which require precise annotations. A computer vision application uses it to outline objects and objects of interest in an image, such as the boundaries of people and objects.
Semantic Segmentation
A semantic segmentation technique is used in computer vision to segment images. An image dataset is semantically segmented to locate all categories and classes. An image is semantically segmented by assigning labels to every pixel.
The technique allows for pixel-level recognition, understanding, and differentiation of objects within an image. Each pixel in an image is assigned to a class based on its location and the boundaries of the object. In addition to autonomous navigation and medical imaging, it is used for object detection as well.
3D Point Cloud Annotation
A 3D point cloud annotation involves labeling and annotating 3D point clouds in order to facilitate analysis and understanding of image datasets, such as buildings, vehicles, roads, trees, and other landmarks.
Using the annotation technique, digital 3D models can be produced, which can be used for various applications like 3D mapping, 3D visualization, and 3D modeling. We at Cogito deliver image annotation services using automated algorithms and manual annotation, ensuring accuracy and speedy delivery of 3D point cloud annotated data sets.
