Content-Based Image Retrieval (CBIR) systems employ color as primary feature with texture and shape as secondary features. In this project a simple, image retrieval system will be implemented

Texture Features Pros Cons
Steerable Pyramid Support any number of orientation Subband undecimated hence more
computation and storage
Contourlet Transform Lower Subband decimated Number of orientation supported needs
to be power of 2
Gabor Wavelet Transform Achieve highest retrieval result Result in over-complete representation
of image.
Computationally intentive
Complex Directional Filter Bank Competative retrival result Computationally intentive

4. Problem definition
• Traditional methods of image retrieval are based on associated
metadata such as keywords and text.
• The traditional metadata based image retrieval may suffer from
several critical problems, such as, the lack of appropriate metadata
associated with images, incorrect metadata.
• Limitation of characters in the keywords to express the visual content
of the image.

5. Problem Solution
1) Instead of manual typing keywords its better and efficient to search
with images in a large database as keywords may not capture every
details which is plus point for image based search .
2) Thus we will build a system that can filter images based on their color
and texture .
3) For color retrival we are using HSV with CCV and for texture GLCM
algorithms.

10. Performance measurement
parameter:
• To evaluate the retrieval efficiency of the proposed system, we use the
performance measurefor color is histogram euclidean distance
,histogram intersection distance .
• For texture parameters are constrast,homogeneity,energy & corelation.
• Precision= Number of relevant images retrieved / Total number of
images retrieved
• Recall= Number of relevant images retrieved / Total number of relevant
images

11. Applications of CBIR:
1) Art Collections Example: - Fine Arts Museum of San Francisco
2) Medical Image Databases Example:-CT, MRI, Ultrasound,
3) Scientific Databases Example:-Earth Sciences
4) General Image Collections for Licensing
5) Architectural and engineering design
6) Fashion and publishing

12. Future Scope:
1) Increasing retrieval performance.
2) Fine-tuning may be done adding some shape and structure
3) Finger print recognition, retina identification, object detection, etc for
large image databases.
4) There is a scope for time optimization also.
5) Extend this in web based applications.
