Computer Vision Annotation Services

How to Outsource Computer Vision Annotation Services

The area of computer science known as computer vision focuses on the development of digital systems that are capable of processing, analyzing, and making sense of visual data, such as images or videos, in the same manner that humans do. The teaching of computers to process and comprehend an image down to the pixel level is the foundation of computer vision. Technically, special software algorithms attempt to retrieve visual information, manipulate it, and interpret the results.

Teams of human annotators make extensive annotations of images for image annotation projects. The ML annotation specialists need to be well-versed in the project’s requirements and skilled at making precise annotations.

Computer vision annotation is used in many different businesses and industries. Here are just a few use cases:


Autonomous Vehicles

The ML models for autonomous vehicles make use of videos that have been labeled to comprehend the surrounding environment. It is mostly used to identify things on the street and other cars in the area of the car.


Medical Imaging

Medical science is becoming more and more dependent on machine learning. Videos are used in many diagnoses. Annotation is required to use this data for ML models to diagnose. Videos can be annotated and ML models trained to speed up this process.



ML models can identify humans or objects in each frame and keep track of them and their movement in subsequent frames thanks to a precisely annotated video dataset.

Facial Recognition

Machines can recognize and identify specific facial markers by using landmark annotation. Dots on a face are used to identify facial characteristics like the shape of the eyes.

Computer Vision Annotation Services We Provide

When data annotation and video annotation service solutions are implemented correctly, they can offer many benefits to businesses. Some of the services we offer at include:

Bounding boxes

One of the most common and straightforward image or video annotation methods used to train computer vision models is bounding boxes. Object classification and localization models can be trained with the right amount of data and precise annotations by drawing boxes around objects of interest in the image.

Video transcription

Using automatic speech recognition technology, we can transcribe your video files. This helps with storage space in a big way as video files are much larger than text files.

Semantic Segmentation

Every pixel in an image is labeled using semantic segmentation, also known as pixel-level labeling, so that your computer vision algorithm can recognize the segments. Full semantic segmentation, in contrast to polygonal segmentation, which is only used to find a specific object of interest, gives a complete understanding of every pixel of the scene in an image and can be useful when there are few sources of data.

Lines and Splines

Lines and splines can be used for a lot of different things, but the most common use for them is to teach machines to recognize lanes and boundaries. Annotators simply draw lines along the boundaries that you want your machine to learn, as their name suggests. Warehouse robots can be trained to accurately place boxes in a row or items on a conveyor belt using lines and splines. Autonomous vehicles are the most prevalent use of lines and splines annotation. Autonomous vehicles can be trained to understand boundaries and stay in one lane without veering by marking sidewalks and road lanes.

Polygonal Segmentation

When working with objects that have irregular shapes, the perfect solution is to use polygonal segmentation annotation. Polygons are more precise when it comes to localization and reduce confusion when training your computer vision models, in contrast to boxes, which can capture a lot of unnecessary objects and noises around the target.


Relation extraction

As a vital part of NPL, this is the process of predicting attributes and relations for entities in a sentence. This task is key to building relation knowledge graphs and is very important to structured search, sentiment analysis, question answering, and summarization applications.

3D cuboids

This is a 3D image annotation method for giving two-dimensional bounding boxes a 3D point cloud annotation dimension. In cuboid annotation, the object's approximate depth is added to its usual length and width, revealing its stature, revolution, profundity, and relative position. The construction of ground truth datasets is made possible by the use of 3D labeling cuboid annotation, which transforms two-dimensional videos and images captured by the camera into fully enacted 3D boxes.

Key-Point and Landmark

Dot annotation, also known as key-point and landmark annotation, generates dots or points throughout a picture. Other names for it include pose estimation and dot annotation. Dots are used to cover objects in an image. This helps AI models and computer vision machines measure the object's dimension and other features so they can use them again when the same object appears. Media can be identified in this manner.

Data Labeling For Other Types Of Machine Learning

Labeling and annotation services can be applied to many different types of machine learning processes. Let’s look at a few of the services we offer for other types of machine learning:

NLP (Natural Language Processing )

The term “natural language processing” (NLP) refers to the subfield of computer science known as “artificial intelligence” (AI), which focuses on making computers capable of comprehending written and spoken language in a manner that is comparable to that of humans.

Computational linguistics, which is the rule-based modeling of human language, is combined with models from statistical, machine learning, and deep learning in NLP. This service allows computers to process human language in the form of text or voice data and “understand” its full meaning, including the speaker’s or writer’s intention and sentiment.

Speech Annotation

The process of labeling and adding metadata to audio datasets is known as speech annotation services. It is a subset of data labeling that is used to train additional NLP models like virtual assistants, chatbots, real-time translation, and other voice recognition systems.

It is necessary to train ML annotation models to differentiate between audio and speech patterns for them to accurately respond to human speech. Audio annotation, like all other types of annotation, such as text and image annotation, requires human judgment to accurately label and tag audio data. For the artificial intelligence (AI) model to successfully link the input data and perform tasks or react accordingly, additional factors like semantic, morphological, phonetic, and discourse data must be identified.

Machine Learning Data Classification

Classification is a supervised method of machine learning in which the model attempts to determine the appropriate label for a given set of input data. The model is fully trained using the training data during classification, and then it is tested on test data before being used to predict new, unseen data. An algorithm can, for instance, learn to determine whether an email is spam or not.
