  • 1. A User-Oriented Image Retrieval System Basedon Interactive Genetic AlgorithmABSTRACT:Digital image libraries and other multimedia databases have been dramatically expandedin recent years. In order to effectively and precisely retrieve the desired images from alarge image database, the development of a content-based image retrieval (CBIR) systemhas become an important research issue. However, most of the proposed approachesemphasize on finding the best representation for different image features. Furthermore,very few of the representative works well consider the user’s subjectivity and preferencesin the retrieval process. In this paper, a user-oriented mechanism for CBIR method basedon an interactive genetic algorithm (IGA) is proposed. Color attributes like the meanvalue, the standard deviation, and the image bitmap of a color image are used as thefeatures for retrieval. In addition, the entropy based on the gray level co-occurrencematrix and the edge histogram of an image is also considered as the texture features.Furthermore, to reduce the gap between the retrieval results and the users’ expectation,the IGA is employed to help the users identify the images that are most satisfied to theusers’ need. Experimental results and comparisons demonstrate the feasibility of theproposed approach.Existing System:• In the existing system the CBIR method faced a lot of disadvantage in case of theimage retrival.• The following are the main disadvantage faced in case of the medical field -Medical image description is an important problem in content-based medicalimage retrieval.

  • 2. is proposed according to the main sources to get semantic features currently.Hence we propose the new algorithm to over come the existing system.• In existing system ,Images were first annotated with text and then searched usinga text-based approach from traditional database management systems.Proposed System:• In case of the proposed system we use the following method to improve theefficiency. They are as follows.• We implemented our models in a CBIR system for a specific application domain,the retrieval of coats of arms. We implemented altogether 19 features, including acolor histogram, symmetry features.• Content-based image retrieval, uses the visual contents of an image such as color,shape, texture, and spatial layout to represent and index the imageHardware Requirements• SYSTEM : Pentium IV 2.4 GHz• HARD DISK : 40 GBwww.nanocdac.com www.nsrcnano.com branches: hyderabad nagpur

The nameof the model comes from the initials of the three additive primary colors, red, green, andblue. The main purpose of the RGB color model is for the sensing, representation, anddisplay of images in electronic systems, such as conventional photography.www.nanocdac.com www.nsrcnano.com branches: hyderabad nagpur
  • 4. In this module the RGB Projections is used to find the size of the image vertically andhorizontally.2) Image Utility:Whenever minimizing the error of classification is interesting for CBIR, thiscriterion does not completely reflect the user satisfaction. Other utility criteria Closer tothis, such as precision, should provide more efficient selections.3) Comparable Image:In this module a reselection technique to speed up the selection process, whichleads to a computational complexity negligible compared to the size of the database forthe whole active learning process. All these components are integrated in our retrievalsystem, called RETIN and the user gives new labels for images, and they are compared tothe current classification. If the user mostly gives relevant labels, the system shouldpropose new images for labeling around a higher rank to get more irrelevant labels.4) Similarity measure:The results in terms of mean average precision according to the training set size(we omit the KFD which gives results very close to inductive SVMs) for both ANN andCorel databases. One can see that the classification-based methods give the best results,showing the power of statistical methods over geometrical approaches, like the onereported here (similarity refinement method).5) Result:www.nanocdac.com www.nsrcnano.com branches: hyderabad nagpur
  • 5. Finally, the image will take the relevant image what the user search. One can seethat we have selected concepts of different levels of complexities. The performances gofrom few percentages of Mean average precision to 89%. The concepts that are the mostdifficult to retrieve are very small and/or have a much diversified visual content. Themethod which aims at minimizing the error of generalization is the less efficient activelearning method. The most efficient method is the precision- oriented method.• Graph:This module is used to determine relationships between the two Images. The precisionand recall values are measured by simulating retrieval scenario. For each simulation, animage category is randomly chosen. Next, 100 images are selected using active learningand labeled according to the chosen category. These labeled images are used to train aclassifier, which returns a ranking of the database. The average precision is thencomputed using the ranking. These simulations are repeated 1000 times, and all valuesare averaged to get the Mean average precision. Next, we repeat ten times thesesimulations to get the mean and the standard deviation of the MAPInput/Output:The image will take the relevant image what the user search. one can see that we haveselected concepts of different levels of complexities. The performances go from fewpercentages of Mean average precision to 89%.
