Data annotation creates an outstanding base for any project. It is the heart of AI and Machine Learning (ML) algorithms, which affects algorithmic performance. To learn and recognize input data, annotation and enhancement are essential for AI and ML models. It is defined as Data classification and labeling for AI applications. Therefore, training data must be appropriately annotated and categorized for any use case. Image annotation is crucial for numerous applications, along with robotic imagination and prescient, computer vision, facial popularity, and devices getting to know-based photograph interpretation structures. In this blog, we will go deep into image annotation, from its basic understanding to the steps taken for it. We will further dig into its types, use cases, Macgence’s workflow for data annotation services, and Macgence as your good choice for data services.
What Is Image Annotation?
Image annotation is labeling an image, strategically involving human-powered work and, sometimes, computer-assisted help. It is essential in creating computer vision models for tasks like image segmentation, image classification, and object detection. Image annotation can range from annotating every group of pixels within an image to one label for an entire image, and it comes under data annotation services.
Successful image and data annotation projects involving computer vision are built on high-quality annotation. The type of annotation needed will depend on the use case the project is designed for.
Steps in Image Annotation
Step 1: Collecting Images
It collects the images for annotation and organizes them into folders with the help of data annotation services.
Step 2: Labeling Images
Each label identifies the activities and objects contained in the images.
Step 3: Verifying Accuracy
The labels are then verified for accuracy.
Step 4: Uploading Data
The team uploads the data to a database for use in ML models.
Types of Image Annotation for Computer Vision
2D Bounding Boxes
It defines the boundaries of objects in a two-dimensional space using graphic representations. The boxes are usually used in computer vision and ML applications for separating areas of interest for objects.
Object Detection
This involves detecting semantic objects about a particular class (humans, buildings, or cars) concerning digital images and videos.
Key Point Annotation
By connecting multiple dots, the image annotation services recognize facial gestures, human poses, expressions, emotions, body language, and sentiments.
Polygon Annotation
This involves marking and drawing shapes on a digital image. It allows marking objects within an image based on their position and orientation. It consists of labeling images of irregular dimensions.
3D Cuboid Annotation
This is used for detecting and recognizing 3D objects in images. It helps machines determine the depth of vehicles, people, buildings, and other objects.
Semantic Segmentation
Data annotators use a semantic segmentation technique to segment images. They semantically segment an image dataset to locate all categories and classes.
Image Classification
Images or objects are classified within images per custom multi-level taxonomies like land use, crops, etc. It converts image data into image insights for AI and ML models.
Skeletal Annotation
This is used to highlight body movement and alignment. Data annotation annotators connect lines on the human body through this technique. They connect them with dots at points of articulation.

Our image annotation workflow
- Analyzing Requirements
When receiving a service query, our data annotation experts understand the clients’ annotation requirements and define the scope of work.
- Preparing Image Dataset
We receive image datasets from clients and prepare them for data annotation. We weed out irrelevant, blurred, or obscured images from the dataset.
- Specifying Objects
Once we prepare the image dataset, we specify different objects and elements in the images that need annotation.
- Assigning Image Labels
We assign labels/tags to images, following different image annotation services- bounding boxes, key points, lines & splines, etc.
- Exporting Images & Quality Checking
After labeling the images precisely, we export the images. Further, this data goes through multiple quality checks to ensure high accuracy in the labeling process.
- Delivering Project
After thoroughly checking the annotated dataset, our image annotation services deliver the final output to the clients in the specified format (ideal for training datasets).

FAQ’s
Ans: – In ML and deep learning, image annotation is the process of labeling or classifying an image using text, annotation tools, or both to show the data features you want your model to recognize. When you annotate an image, you are adding metadata to a dataset.
Ans: – For AI-based applications and ML models to function correctly and understand elements the same as humans, image annotation is fundamental. For example, image annotation helps an autonomous car differentiate between a mailbox, pedestrian, red light, people, trees, etc., to make appropriate driving decisions. Hence, image tagging enables the recognition system to process millions of images and precisely understand different objects in a frame.
Ans: – Data labeling is commonly used in sentiment analysis, text classification, and categorization applications. Data annotation, which provides richer context, is often employed in computer vision tasks like object detection, image segmentation, and autonomous driving systems.
