CBIR is about developing an image search engine, not only by using the text annotated to the image by an end user (as traditional image search engines), but also using the visual contents available into the images itselves.
Initially, CBIR system should has a database, containing several images to be searched. Then, it should derive the feature vectors of these images, and stores them into a data structure like on of the “Tree Data Structures” (these structures will improve searching efficiancy).
A CBIR system gets a query from user, whether an image or the specification of the desired image. Then, it searchs the whole database in order to find the most similar images to the input or desired image.
The main issues in improving CBIR systems are:
- Which features should be derived to describe the images better within database
- Which data structure should be used to store the feature vectors
- Which learning algorithms should be used in order to make the CBIR wiser
- How to participate the user’s feedback in order to improve the searching result
- …

My final thesis is about improving a CBIR system by menas of learning algorithms. So I will write about it in detail here.
I am currently working on these issues:
- Color and texture feature derivation
- Image blocking (related to the previous one)
- Color Indexing
very interesting.

Sir
I am Vijina.V.P, doing Mtech in “computer vision and image processing” from Amtia University,India.My project work is in “Content Based Image Retrieval”.I am thinking about how to improve the performance of existing CBIR systems.Can you suggest some points so that i can work on that?
Thanking You

Then, mentioned problem is an extensive issue, but the popular methods are
- using user’s relevant feedback to improve your search result
- using better Feature extarction methods (like Histogram Improvement)
- improve the indexing mechanisms
- decreasing the size of feature vector
and so on.
I have to improve my CBIR, so I will write about it during my project completion.

Hi Madam,
I am a student of BITS Pilani, and am currently doing a project on Content Based Image Retrieval. Your help in this regard will be highly appreciated. Please give me your email address if possible. Send me a mail on kg.coolhead@gmail.com
The project is still in its nascent stages. The primary problem i have been facing is what criteria to choose for the images. I thought about color and texture, but using them implies that i have to deal with a complete matrix for each image seperately slowing down the search considerably. If these properties are considered globally then the results will be highly hampered.
Please help me out / Contact me through mail if possible
Thanks a lot

hai, i’m ana..
i’m doing thesis on” CBIR system focusing shape similarity”
can you suggest any idea on my thesis?
Hey can I wanna do project on CBIR based on color. can any1 suggest me which Algoritm should i use n wher ll i find it..
