Ascii2D

Classes

Ascii2D

Bases: BaseSearchEngine[Ascii2DResponse]

API client for the Ascii2D image search engine.

Ascii2D provides two search modes
  1. Color search: Finds images with similar color combinations (default mode)
  2. Feature search: Finds images with similar visual features (bovw mode)

Attributes:

Name Type Description
base_url str

The base URL for Ascii2D searches.
bovw bool

A flag to enable feature search mode.
Note
  • Color search (bovw=False) is recommended for finding visually similar images
  • Feature search (bovw=True) is better for:
    • Cropped images
    • Rotated images
    • Images with different color schemes
  • Feature search may be less accurate with heavily modified images
