For optimal results, use images with white background and black symbols. Images with dark backgrounds will be automatically inverted, but may reduce detection precision.

Help & Instructions
How Symbol Detection Works
Application Flow
  1. Upload an image with symbols (ideally black symbols on white background)
  2. Adjust detection parameters if needed (see explanation below)
  3. Click "Process Image" to detect and group similar symbols
  4. Select symbol groups and assign replacement characters. Click on each group to view all symbols and exclude any that don't belong by using the checkboxes.
  5. Click "Apply Replacements" to generate the result image
  6. Download the final image with symbols replaced by text
Detection Parameters Explained
  • Symbol Dimensions: Define the size range (in pixels) for symbols to detect. Adjust these values based on your image resolution and symbol sizes.
  • Target Number of Groups: Estimate how many different unique symbol types exist in your image. This helps the clustering algorithm.
  • Clustering Sensitivity: Controls how similar symbols must be to be grouped together.
    • Higher sensitivity → More groups, more precise but might split similar symbols
    • Lower sensitivity → Fewer groups, more tolerant of symbol variations
Tips for Best Results
  • Use high-contrast images with clear symbols
  • For runes and symbols, using images with black symbols on white backgrounds works best
  • If symbols aren't detected, try adjusting the min/max width and height parameters
  • For symbols that are grouped incorrectly, adjust clustering sensitivity
  • Use the "Regroup Excluded Symbols" feature to better organize similar symbols
  • Click on symbol groups to select/deselect them for replacement
