Introduction
Need for Image Retreival System Different Approaches
Query-by-Example(QBE) Query-by-Concept(QBC)

Monotonic Approach
Organizes the image in Heirarchial Structure

ASIA Technique
Annotation is done by high level concepts such as ‘car’, ‘water’ etc.
Datbase images are matched based on the concept.

Experimental Studies

Conclusion
Monotonic approach annotates the images based on a model. The model does not differentiate the real world objects.
AISA approach can annotate the images which are complex. It does the matching offline and is much faster in retrieving the image.
