If you want to go further in your projects, annotate larger volumes or benefit from a workforce that speaks more than 17 languages, meet isahit's team and discover their different labelling solutions !

Video annotation allows intelligent systems to recognize and identify objects, patterns, and more, based on the labeled data provided to them. 

What is video annotation for machine learning?

Video annotation for computer vision and AI learning is absolutely necessary. An instance it can be used is for training a self-driving car. From training autonomous vehicles to detecting roadblocks, pedestrians, and obstacles are good at determining poses and activities, video tagging has a role to play in training almost any vehicle model. This is perceptual AI. Machine learning and computer vision models can learn using the labeled datasets, eventually used to train the algorithms.

How does video annotation outsourcing work?

Just like image annotation, video annotation is used to build AI and machine learning models to be able to recognize real-world objects. But unlike images, its static counterpart, collecting video data can be much more complex. One way that you can ensure the quality of datasets is human-assisted data-labeling. It is always best to outsource this task to professionals who specialize in video annotation. With a human involved, practical insights can be quickly generated, leading to greater efficiency 

Types of video annotation services

1. Semantic segmentation:

If you want to develop more targeted and accurate computer vision AIs, you might consider semantic segmentation, which is about classifying images at the pixel level.

2. Polygon annotation:

This technique is best used for verticals that require a flatter approach to labeling features. It is used to annotate pipelines, roads, railways and datasets regarding road markings, lanes etc

3. Bounding boxes:

Arguably the most reliable video tagging technique, Bounding Box annotation is all about the idea of imaginary rectangles for detecting objects.

- 2D bounding boxes:

This basically involves creating rectangular boxes for object identification, categorization and labeling. When doing this, annotators need to manually draw boxes around the object in focus.

-3D bounding boxes:

This is quite similar to 2D bounding boxes. In this type of video annotation is applied to get a more realistic 3D visualization of a specific item. With 3D bounding boxes, you get more accurate results as it can also help you define the breadth, length, and depth of the object, even when it is in motion.

4. Landmark annotation:

This is often used to identify even the least visible of shapes, postures, or objects. This method involves creating dots all through an image and then linking them to create a skeleton of the object across each frame, key point, and landmark. This method is most suitable for detecting facial features, postures, face recognition, etc.

What is video annotation? 

Video annotation is a process of training the computer to recognize objects. It forms part of the wider Artificial Intelligence field of Computer Vision. It teaches the computer to imitate the perspective traits of the human eye. Video annotation may include comments, shapes or drawings placed on or over a video frame.


What is a video annotation tool? 

A video annotation tool is a text or drawing tool that helps you to add information to a text, an image, database, or any other piece of content. An annotation tool performs a lot of other functions. It can be applied to other formats as PowerPoint Presentation to annotate the selected content of interest. Annotating complicated and sophisticated videos with high levels of accuracy, precision, and context is the main aim of a video annotation tool. They are important because it allows you to easily define the frames per second according to your peculiar needs.

How to know the best video annotation tool to choose

It is imperative to have a step-by-step guide when choosing the best video annotation tool.


a) Know your need

Prior to choosing the best video annotation tool to suit your needs, you must have clarity. What do you seek to achieve? You must know why you are annotating your video data? You must identify if it is for a long or short-term project. Being knowledgeable of this will help you choose the appropriate video annotation tool. Hence, if it is a long-term project, it will be appropriate to purchase a studious and dedicated tool. However, if it is only for a short-term project, then probably outsourcing will be a better alternative.


b) Identify your selection criteria

As already mentioned, if it is for a short-term project, then outsourcing is more economical. So, when it comes to outsourcing the service, there are certain technical aspects to be taken into consideration. A video annotation tool must be chosen:

I.  Based on application

II.Based on efficiency

III.Based on formatting

IV.Based on functionality

Having said this, it is important to also consider the price, the functionality, the quality, and efficiency of an annotation tool before purchasing.


c) Evaluate and re-evaluate

After identifying your selection criteria, the next important thing is to thoroughly search and evaluate vendors on the market that can supply your needs. In doing so, it is important to ensure that the selected vendor provides you with flexibility and post-purchase services that will align to your specific needs.
