# Choosing Blob Analysis

Blob analysis is not appropriate for every vision application. The following characteristics suggest that an application is suitable for blob analysis:

- Images of two-dimensional objects
- High-contrast images
- Presence/absence detection
- Requirements for scale and rotational invariance

Applications with the following characteristics are probably not suitable for blob analysis:

- Low-contrast images
- Essential features within the scene cannot be represented using just two grey levels
- Requirement for pattern detection
