CVAT Annotation


Machine learning model structuring and processing is not as easy as it may sound. Without the availability of required data, it is difficult to imagine the accuracy of results. At the core of several AI programs wherein complex computations are done, machine learning algorithms also enable the systematic rendering of learning tasks.

As much as the quality of data is central to an algorithm, following the stages of applying the data for performance decides the accuracy of prediction. Whether the data is limited or available in ample amounts, imagining data annotation manually isn’t a practical solution when business demands are changing rapidly. Computer vision tasks, particularly, demand massive data pools for providing results that power the AI implementation in autonomous vehicles or advanced on-premise security systems. Therefore, manual data annotation usually is out of the question.

How big computer vision annotation demand can get?

Deep learning can make matters for data utilization colossal. Before moving to any computer vision annotation tasks, it is vital to get a good understanding of the tool. Prominent industries which are making use of computer vision in generosity are manufacturing, construction, retail, agriculture, and transportation. Computer vision annotations are image-based and done for videos.


To find how big computer vision tasks can get can be ideally elaborated through the ADAS technology in autonomous vehicles. Most autonomous vehicles are equipped with machine learning algorithms and deep learning structures, integrated to perform complex utilization of data at high velocity and Institute localization for the vehicle. Computer vision is a major thread holder in the simultaneous processing of massive data for the vehicle in the environment. The data utilization can mount to millions of images for data labeling. For such high-caliber tasks, considering appropriate annotation tools like CVAT halves the burden.

It supports annotation for object detection, image classification and segmentation tasks, along with annotation of videos as well.

Working with CVAT

Most computer vision tasks involve the annotation of heavy images and videos, thus arranging the server space is essential. The next step is to run CVAT on local machines to perform annotations. Tools like CVAT tools are easy to install via cloud host and run installation on the local machine. Before installation, analyzing the storage space requirement is vital too. When human-in-the-loop workforce solutions start operating the tool, CVAT proves highly scalable. The usage of tools is simple and hassle-free, hence, post-installation, the workforce can easily be trained to use CVAT. Tasks for annotation can be divided among the workforce and the single instance of CVAT running should be enough for annotation.

When the CVAT installation is complete, it offers hassle-free general usage for annotation of images and videos. The tool also supports uploading and annotation of multiple file formats.

Here are some steps to better explain the annotation process set up:

1- Non-admin accounts can log in to the account once the installation is successfully done.

2- After logging in, start working on the pre-existing computer vision annotation tasks. Else, create a new task with the New Task option.

3- Once a new task is created, account users will see the task every time they log in.

4- Start labeling as per the given options, read the usage instructions for the in-built tools handy.

5- After annotation, export the data in the required format; there are multiple formats available to select from.

If we take a business case instance for using CVAT, a labeling firm annotated sports images with predefined categories within days using the tool. Any discrepancies in labeling were fixed in second-tier quality checks while the in-built options provided multi-faceted support to finish tasks as swiftly as possible. Elaborating further on the case, CVAT was used in annotation of about 5000 images for a brand operating in the fashion segment by human-in-the-loop workforce solutions provider Cogito Tech LLC. Annotation was carried out by a skilled team of annotators. The annotation was easy with in-built options to drag shapes and mark images in free form. CVAT supports bounding box, semantic segmentation and video annotations.

For CVAT to work without hiccups, the right way of installation can help your project cross the finishing line without stressing.

End Note:

CVAT is a versatile tool and should be ideal for all types of computer vision annotations. Checking on the storage requisites is recommended before initiating tasks. Also, cross-check the quality of annotated files in every instance before finally downloading the files. It suffices for all your computer vision annotation needs. The training data created for the machine learning model is also suitable for further manipulations. As much as it helps in images annotation, for videos too, CVAT works as appropriately. Don’t wait or hover around to help you through your computer vision models, simply go for the tool and experience the ease of usage. Originally published atManaging Computer Vision Tasks with CVAT
