The foundations for biometrics or identification systems were laid long ago. Today these developments have contributed to the identification of people, access to private sites and all places that need security and order with the help of computerized
This paper proposes to give review on algorithms which helps to match human face on Aadhar card with their current image using Content based Image Retrieval CBIR .The concert of Content Based Image Retrieval CBIR system is depends on competent featur
Due to internet explosion there has been considerable rise in transmission of data such as tex, images, text, videos, etc over internet. Here security is required for transmission of data over internet so that data is secure from sender to receiver.
Image Denoising is an important pre processing task which is used before further processing of image. The purpose of denoising is to remove the noise while retaining the edges and other detailed features. This noise gets introduced during the process

CONTENT-BASED IMAGE RETRIEVAL “A picture speaks more than a thousand words !!” Presented By: D.SRIKANTH V.M.SRI KRISHNA G.SRIRAM B.ABHILASH
INTRODUCTION

INTRODUCTION
Image Retrieval system for retrieving images from large database of digital images
Common method of image retrieval utilizes metadata / keywords
Manual image annotation is time ti me consuming
Locating desired image from small database is possible, where as in large database more effective techniques are needed
3
EXISTING SYSTEM
QBIC supports users to retrieve image by colour, shape and texture
QBIC provides several query methods
Simple Query
Mutli-Feature Query
Mutli-Pass Query
4
EXISTING SYSTEM
Photo Book system supports users to retrieve image by colour, shape and texture
Photo Book provides set of matching algorithms, divergence, vector space angle, histogram and Fourier peak
5
PROPOSED SYSTEM
Currently most widely used image search engine is GOOGLE. It provides its users with textual annotation. Not many images are annotated with proper description so many relevant images go unmatched
Quadratic Distance yield metric distance IRM is non-metric and gives result that are not optimal
6
PROPOSED SYSTEM
Our proposed system uses modified IRM and colour feature which overcomes above mentioned disadvantages
We also provide an interface where user can give query images as input, automatically extracts the colour feature and compared with the images in database, retrieve the matching image 7
Update the database according to the users request.
Classify the images for efficient searching.
12
USER MODULE
Upload the query images.
13
SEARCHING MODULE
Searching based on a given image.
Integrate the search with the existing application.
Combine querying techniques with content independent metadata.
14
IMAGE FEATURES
•
•
Texture (Laws, Gabor filters, local binary partition) Color (histograms, grid layout, wavelets)
•
Shape (first segment the image, then use statistical or structural shape similarity measures)
•
Objects and their Relationships
