3. Abstract
 Content-Based Image Retrieval (CBIR) has become one of the most active areas in
research in the past few decades. Since, the numbers of digital images are hugely
available and are growing.
 Hence, one of the fields that may profit more from CBIR is medical area, where
generation of digital images is huge. Surgeon can query image databases to detect
tumours and malformations in X-rays or Magnetic Resonance Images (MRI) based on
the image content.
 Extensive research has been done to develop methods to ensure that queries become
faster and more effective but several problems related to semantic meaning of image
content along with retrieval efficiency in large databases are yet to be solved.
 Retrieval of images based not on keywords or annotations but based on futures
extracted directly from the image data.

4.  Searching a large database for images that match a query.
 The term CBIR was coined by T. Kato in 1992, to describe
experiments into automatic retrieval of images from a
database, based on the colors and shapes present.
 Why CBIR??????
 What kinds of queries?
 Applications of CBIR
Content-based Image Retrieval (CBIR)

5. Applications
 In Biomedical
 In crime anticipation
 In military
 In architectural and manufacturing
 In fashion and interior design
 In geographical and remote sensing systems
 In cultural heritage
 In education and training
 In World Wide Web searching

6. What is a Query?
 an image you already have
How did you get it?
 a rough sketch you draw
How might you draw it?
 a symbolic description of what you want
What’s an example?

7. How to search images?????
• Color • Shape
Color is one of well known
element of an image for
identifies the proportion of pixels
within an image holding specific
values (that humans express as
colors).
Shape does not refer to the
shape of an image but to the
shape of a particular region
that is being sought out.

8.  Texture
Texture measures look for visual patterns in images and how they
are spatially defined. Texture is a difficult concept to represent.

9. Literature Review

10. Literature Review

11. Literature Review

12. Problem Formulation
1. Need for an efficient image retrieval system.
2. Semantic gap: Mismatch between user requirements and
capabilities of CBIR system.
3. Perception subjectivity: User interpretation and understanding
of images tend to be uncertain.

13. Objectives
1. To improve the performance of cbir system to achieve better
accuracy.
2. To implement various features of images for cbir listed below:
1. Contrast
2. Mean and Standard deviation.
3. Entropy
4. Energy
3. Applying Similarity measures.

14. Proposed Work

15. Result

16. Chest as query image (p=0.95, r=0.2, acc=79.75%)
Query Image Retrieved Images

17. Knee as Query Image (p=1, r=0.21, acc=80.25%)
Query Image Retrieved Images

18. Brain as query image (p=1, r=.2, acc=80.25%)
Query Image Retrieved Images

19. Precision, Recall and Accuracy
Test Image Precision Recall Accuracy (%)
Knee 1 0.50 88
Brain 0.96 0.48 87
Chest 0.66 0.33 79

20. Conclusion
 The proposed method is simple and fast in retrieval.
 The average precision evaluated for the proposed
approach is up to 87.3%.

21. Future Scope
 Reduce the query execution time.
 Updating fuzzy rule base weights.
 To apply Neural-Network to further Improve the quality
of results
