Whether you are working on computer vision projects or dealing with machine learning systems, AI video annotation tools are part of the standard practice.
Video annotation tools, as their name suggests, are specialized tools that help users add additional info to a video. This addition of information is known as ‘annotation’, and users can annotate a video either during the recording session or before/after they have recorded the video.
The right video annotation tools can empower you to annotate your video in minutes. They contribute a great deal to improving the algorithm by giving it more context. Besides that, they increase the efficiency of visual learning.
If done correctly, annotating a video can boost engagement by making your videos more interactive and smartly segmenting them so one can retrieve them without wasting any time.
Moreover, annotating your videos, i.e., adding visual cues like captions, notes, etc., to your videos can enrich your audience’s viewing experience. While numerous video annotation tools are available in the market today, not all of them are as capable as they claim to be.
In this article, we have curated some of the top video annotation tools to enhance your visual data and eliminate any confusion. Read on to find out.
What Is a Video Annotation Tool?
Video annotation is the process where a user labels or tags video clips to make it possible to train computer vision models or detect objects. As mentioned earlier, video annotation tools are tools that help annotators annotate a video with ease.
Proper annotation on videos can give birth to an accurate reference database. With such a database at their disposal, AI-powered systems will be capable of identifying objects like cars, humans, animals, etc., way more quickly and precisely.
Key Features to Look Out for a While Choosing a Video Annotation Tool
Before choosing a video annotation tool, you should ensure the presence of these must-have features:
#1. Multiple Annotation Types
Your video annotation tool should support various annotation types, such as bounding boxes, semantic segmentation, rapid annotation, polygon annotation, key point annotation, etc.
#2. User-Friendly UI and Ease of Access
The tool should have a simplistic, intuitive UI that is easy to navigate. If users have to spend ages getting familiar with a tool, it isn’t the one.
#3. Easy Sharing
A good video annotation tool must allow users to share their videos with their team and make timestamped notes on them in real-time. This ensures each team member stays on the same page and produces the best possible result.
The tool should easily integrate with other platforms and tools. This lets the software go beyond its limits and increase its efficiency.
#5. Dynamic Classifications
An ideal video annotation tool should let you categorize frames and events. Such action-based or event-based classifications help annotators describe what an object is doing over a set number of frames.
