Content based Image Retrieval using Combination between Moment and DCT Methods
نویسندگان
چکیده
In this paper a content based image retrieval CBIR is introduced, a color is one of the important features in image processing and CBIR so the Discrete Cosine Transform (DCT) and Color Moment(CM) used to extract features of a query image to compare with image feature in database, the two methods DCT and Color Moment have best result when apply the program by using WANG database images and test 100 image from the database 10 image from each class, the average retrieval of precision of combination DCT and moment with constant weights was 89.3% and the best results were obtained from making the weights variable was 90.7%. and the best results were obtained from dinosaurs , elephants, flowers classes. General Terms Image retrieval , combination algorithms , Content Based Image Retrieval .

Image retrieval using the combination of text-based and content-based algorithms
Image retrieval is an important research field which has received great attention in the last decades. In this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. For text-based features, keywords and for content-based features, color and texture features have been used. Query in this system contains some keywords and an input...
متن کاملQuery based Image Retrieval using Kekre’s, DCT and Hybrid wavelet Transform over 1 and 2 Moment
In order to improve the accuracy and efficiency of the image retrieval systems vast research is going on in the direction of Content Based Image Retrieval instead of text based search of images which has got many constraints and drawbacks in the retrieval process. In this paper, we describe the novel techniques to retrieve similar images from large volume of databases based on contents. Feature...
متن کاملA Novel Method for Content Base Image Retrieval Using Combination of Local and Global Features
Content-based image retrieval (CBIR) has been an active research topic in the last decade. In this paper we proposed an image retrieval method using global and local features. Firstly, for local features extraction, SURF algorithm produces a set of interest points for each image and a set of 64-dimensional descriptors for each interest points and then to use Bag of Visual Words model, a cluster...

متن کاملA New Descriptor based on 2D DCT for Image Retrieval
Content-based image retrieval relies on feature comparison between images. So the selection of feature vector is important. As many images are compressed by transforms, constructing the feature vector directly in transform domain is a very popular topic. We propose a new feature vector in DCT domain. Our method selects part of DCT coefficients inside each block to construct AC-Pattern and use D...
