Possible disadvantages of Computer Vision Annotation Tool (CVAT)

• Installation Complexity
  Setting up CVAT can be complex, requiring knowledge of Docker and command-line operations, which may be challenging for non-technical users.
• Resource Intensive
  CVAT can be demanding on system resources, particularly when handling large datasets, which may affect performance on less powerful machines.
• Limited Offline Functionality
  As a largely web-based application, CVAT has limited offline capabilities, which can be a constraint in environments with unreliable internet access.
• Learning Curve
  Despite its user-friendly interface, mastering all features of CVAT can take time, particularly for users who are new to annotation tools or advanced functionalities.
• Scalability Challenges
  While CVAT supports multiple users, scaling it for very large teams or extremely large projects may require additional infrastructure and management.

Possible disadvantages of VGG Image Annotator (VIA)

• Limited Performance for Large Datasets
  When dealing with large datasets, VIA can become slow or unresponsive due to its reliance on browser-based operation which hampers performance scalability.
• Basic Interface
  The interface is quite simplistic and may lack the advanced features or aesthetics found in more sophisticated, dedicated annotation software.
• Lack of Automation for Advanced Needs
  While it supports basic automatic annotation, it is not as advanced or robust for complex tasks, which might require more manual input or additional tools.
• Limited Support
  Being an open-source project, it may not offer the same level of professional customer support or regular updates as commercial tools.
