Top 3 Services to Outsource Your Video Labeling Project To

May 17, 2022

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.
