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    While the documentation is extensive, it can sometimes be incomplete or outdated, requiring users to rely on community forums or external sources for solutions.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.

    Offers competitive pricing plans, including a free tier for limited use, which can be very cost-effective for individuals and small businesses.
  • Versatility
    Supports various image formats and can be used for different types of images, including photos, illustrations, and more.

Possible disadvantages of Removal.ai

  • Dependency on Internet
    Requires a stable internet connection for processing, which may not be convenient for users with limited or unreliable internet access.
  • Limited Free Tier
    The free tier offers limited credits, which may not be sufficient for heavy users or professional needs.
  • Subscription Model
    To unlock advanced features and higher usage limits, users need to subscribe to a paid plan, which may not be ideal for everyone.
  • Variable Performance
    While generally high-quality, there can be occasional issues with complex images where the AI may not perform optimally.
  • Data Privacy
    As with any cloud-based service, there's a potential risk related to data privacy and security, which might be a concern for some users.

  • Are there any ways to rip (dead) gacha game assets?
    If I had to do this, I'd probably try to find a youtube video of the game that happens to have the character in it, take a screenshot of the character, and then use a tool like https://removal.ai/ to extract the sprite. Source: about 2 years ago
  • Some python scripts to handle bulk product image downloading and processing (specifically from shopify)
    At this point, I will need to process all of the images that have a white background with remove.bg. I processed a few images with both remove.bg and removal.ai. Removal.ai was pretty average, leaving white around some very easy objects with sharp edges. Remove.bg was the winner here. It's more expensive but worth it. Source: about 2 years ago
  • Just a reminder that there is a new 'remove background' extension for a1111
    Nice! I've been using Removel.Ai for months and it works really well. Source: about 2 years ago
  • Is this a good thumbnail and title?
    Try making the image darker or scarier using filters. Your headshot could use those white outlines or a brush effect to separate it from the background. Take a photo of yourself with a really scared look and use the site below to mask the image. It's FREE! I use it all the time for suff. https://removal.ai. Source: over 2 years ago
