....In addition to its attribute values, every data point also has a class value between 0 and 9. COREL: This data set contains 31,438 data points with 179 attributes, where each point represents a color image using five image features: the first one is a 64 attribute color coherence vector [19] in the HSV color space; the second one is a 9 attribute color moments [18] extracted from the L a b color space; the third one is a 10 attribute wavelet based texture descriptor [22] the fourth one is a 64attribute edge coherence histogram [6] and the fifth one is a 32 attribute Fourier shape ....

....as well as the evaluation is non trivial. Because the images are in favor of the color feature, we compare the performance of the thesaurus based histogram model with the traditional color histogram proposed by Swain and Ballard [6] and the color coherent vector (CCV) proposed by Pass and Zabih [5], as well as the histogram model [3] in the keyblock framework. To generate the keyblocks, we selected 621 images as the training set. Three block sizes, 2 2, 4 4 and 8 8, are used. For each block size, experiments have been performed to generate the codebooks of three different sizes ....

....have been applied, that represent the histogram by moments [134, 74] or clusters [101] However, the histogram disregards the spatial constellation of the color. Thus very dissimilar images are considered similar. Various solutions to include positional information have been considered: [92, 132] both use the histogram technique and refine the histogram to include the absolute location of the pixel, or some kind of homogeneity information into the histogram. These techniques can work automatically as no preprocessing, like a segmentation, is required. However, incorporating the absolute ....

....used to index images in large image databases. Color histograms, however, do not contain spatial information about the colors. Thus, color histograms are inappropriate for image copy detection. Several methods have been proposed to remedy the shortcomings of color histograms. Pass and Zabih [9, 10] developed the color coherence vector (CCV) method, which partitions each color into a coherent and an incoherent portion. Hsu et al. 4] selected a set of dominant colors from an image and partitioned the image into rectangular regions, each containing one color. Smith and Chang [11] employed ....

....image databases are demanded to provide open access to relevant information and products. Thus, content based image retrieval (CBIR) has become an active research area. A variety of techniques have been developed. In particular, content based image retrieval using lowlevel features such as color [41, 36, 26], texture [21, 35, 34, 40, 20] shape [42, 22, 14, 23, 24, 15, 10, 17, 46, 47, 33, 43, 32] and others [30, 38, 2, 16, 7] extracted from the images has been well studied. Various image querying systems including QBIC [11] VisualSeek [36] PhotoBook [27] and Virage [5] have been built based on the ....

In the second place, from the various image representations that have been proposed for content based retrieval [29], 48] 43] 24] 30] 49] 39] 44] we have selected joint histograms [30] These are simple estimations of multivariate distributions that combine color and scene structure information, and have shown to signi cantly improve color only image retrieval.

The nal point consists in the de nition of the similarity measure.

....RETRIEVELIST. The precision and recall figures were then plotted to demonstrate the performance of SceneryAnalyzer. In Subsection 5. 2, performance with the COREL database will be used to compare SceneryAnalyzer with the keyblock model [17] traditional color histogram [43] color coherent vector [27], and wavelet (Haar and Daubechies) texture techniques [37, 41] All these methods accept only queries by example. The process of selecting query sets and calculating the precision recall for these methods can be illustrated with a typital case, where the sky feature is queried using the keyblock ....
