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..
hai i’m jobin george , doing Ms..i m doin ma project onm CBIR..i hope all these article will help me a lot..i would like to know more about feature extraction and segmentation issues..can any one help me out??
Hola,
I’m working on CBIR, for color analysis part, I have used the following :
Image colour histogram extraction: getPatchHist.m
Histogram comparison using the Bhattacharyya coefficient: compareHists.m
from following URL: http://elm.eeng.dcu.ie/~oconaire/source/
I had to do some changes into my code, getPatchHist, i had to put 2 instead of 16 for the value of the BINS to make my system work, is that correct,
I undrestand that in compareHist.m , the normalization has been used to calculate the similarity, but I need to elaborate and explain more, what else shall I put there?
Thanks in advance,,,
,
ada yang punya tentang content based image retrieval tidak?
kalau ada saya minta jurnal or referensi tentang CBIR dan kalau ada contoh programnya dengan java.
thank’s before……
One of working CBIR system is ges beta. First Lithuanian content-based search system. ges.projektas.lt

Hey can I wanna do project on CBIR based on color. can any1 suggest me which Algoritm and what type of images and what particular features of images to extract the images should i use n wher ll i find it
HI
I am a student studying in PESIT college, Bangalore.
Me and my friends r doing our end sem project on CBIR.
I would really appreciate if u could send me any code related to cbir ,as we have to show it next week.
Thank you
hi,
i am a final yr btech student..
while working with the complete cbir project provided
above it worked well for uncompressed images..but it doesnt
work for compressed images..why is that so?pls help me…can the code be modified such that it can work for compressed images also?
pls give me an idea how to work this code for jpg or smaller images(160*160) in BMP format…i have to show it next week..
pls help me out ..
I am doing a project work on computer aided medical diagnosis system. I know it involves CBIR. Please I need your help. I don’t know how to get started.
Ani.
I want to choose a subject for PhD for medical images , can I use CBIR in this field and what you suggest about this .
Thank you in advance
Best regards
yousif
Dear madam,
I want to do phd in image processing. Can I take CBIR for it. can u suggest about this. Thank u
Salam
please can you help me in HOW can I saving my image data like image color histogram or any scalar value (like the color standard deviation , mean etc.) in a database file in order to use one of Similarity measure to retrieve the closest image to query image ..
thanks
