A New Improved Wavelet Correlogram Method for Image Indexing and Retrieval
نویسنده
چکیده
In this paper, a new algorithm called wavelet correlogram-CCV (W3C) for contentbased image indexing and retrieval is presented. W3C is an extension of wavelet correlogram that utilizes color coherence vectors (CCV) to consider texture information in addition to the shape for gray-level images. Additionally, a new distance measure that is optimized by genetic algorithms is proposed. The retrieval results obtained by the new method on a 1000 non-medical image database demonstrate significant improvements in recall and rank compared to wavelet correlogram and SIMPLIcity methods. Also, simulations on a 1030 medical image database show considerable

Wavelet correlogram: A new approach for image indexing and retrieval
In this paper, a new approach for content-based image indexing and retrieval is presented. The proposed method is based on a combination of multiresolution analysis and color correlation histogram of the image. According to the new algorithm, the wavelet coefficients of the image are computed first using Daubechies3 wavelet. Then, monodimensional color correlogram of the horizontal and vertical...

متن کاملA New Evolutionary Algorithm for Optimizing Content Based Image Indexing Methods
Optimization of content-based image indexing and retrieval (CBIR) algorithms is a complicated and time-consuming task since each time a parameter of the indexing algorithm is changed, all images in the database should be indexed again. In this paper, a novel evolutionary method called evolutionary group algorithm (EGA) is proposed for complicated time-consuming optimization problems such as fin...
متن کاملSpatial Color Indexing and
We deene a new image feature called the color correlogram and use it for image indexing and comparison. This feature distills the spatial correlation of colors and when computed eeciently, turns out to be both eeective and inexpensive for content-based image retrieval. The correlogram is robust in tolerating large changes in appearance and shape caused by changes in viewing position, camera zoo...
متن کاملImage Correlogram in Image Database Indexing and Retrieval
In this paper we present a new approach to image indexing and retrieval based on image correlogram. We show that in comparison with usually used approaches, i.e. image histogram and autocorrelogram, image correlogram gives significantly better results in image retrieval. These results are achievable without increasing computational cost in image indexing or retrieval. In the experimental part o...
