  • Rich Collection of examples
    OpenCV provides a large number of example codes and sample applications, which can significantly reduce the learning curve for beginners.

Possible disadvantages of OpenCV

  • Steep Learning Curve
    Due to the vast array of functionalities and the complexity of some of its advanced features, beginners may find it challenging to learn and use effectively.
  • Documentation Gaps
    While the documentation is extensive, it can sometimes be incomplete or outdated, requiring users to rely on community forums or external sources for solutions.
  • Resource Intensive
    Some functions and algorithms in OpenCV can be quite resource-intensive, requiring significant processing power and memory, which can be a limitation for low-end devices.
  • Limited High-Level Abstractions
    OpenCV provides a wealth of low-level functions, but it may lack higher-level abstractions and frameworks, necessitating more hands-on coding and algorithm development.
  • Dependency Management
    Setting up and managing dependencies can be cumbersome, especially when integrating OpenCV with other libraries or on certain operating systems.
  • Backward Compatibility Issues
    With frequent updates and new versions, backward compatibility can sometimes be problematic, potentially breaking existing code when updating.

Unreal Engine features and specs

  • High-Quality Graphics
    Unreal Engine is known for its ability to produce stunning, high-quality graphics and realistic environments, making it a preferred choice for AAA game development and high-fidelity visual projects.
  • Blueprint Visual Scripting
    Unreal Engine offers a visual scripting system called Blueprints, which allows designers to create complex game logic without any programming knowledge, streamlining the development process.
  • Cross-Platform Support
    Unreal Engine provides robust support for multiple platforms, including PC, consoles, mobile devices, and VR/AR headsets, enabling developers to reach a wider audience with minimal hassle.
  • Large and Active Community
    The Unreal Engine community is large and active, offering extensive resources, tutorials, and forums which can be invaluable for troubleshooting and learning new techniques.
  • Regular Updates
    Epic Games frequently updates Unreal Engine, adding new features, improvements, and optimizations to keep developers equipped with the latest technology advancements.
  • Marketplace
    The Unreal Engine Marketplace offers a vast array of assets, ranging from 3D models to plugins, which can significantly speed up the development process by providing ready-to-use resources.

Possible disadvantages of Unreal Engine

  • Steep Learning Curve
    Due to its extensive features and capabilities, Unreal Engine can be challenging for beginners to master, requiring a significant investment of time and effort to learn.
  • High System Requirements
    Developing with Unreal Engine often requires a powerful computer with strong hardware specifications, which can be a barrier for developers with limited resources.
  • Large File Sizes
    Unreal Engine projects can result in large file sizes, which can be cumbersome to manage, particularly in terms of storage and transfer bandwidth.
  • Complexity for Simple Projects
    For smaller or simpler projects, the capabilities of Unreal Engine might be overkill, and using it can unnecessarily complicate development when compared to lighter engines.
  • Royalty Fees
    Unreal Engine imposes a royalty fee of 5% on gross revenue after the first $1 million USD per product per year, which can impact the profitability of commercial projects.
  • Less C++ Flexibility
    While Unreal Engine supports C++, the engine imposes certain constraints and abstractions that can limit the flexibility developers might need for highly customized or optimized code.
