The modeling of multimedia and especially the semantic gap between the visual features and semantic concepts become an important domain due to the quantity of visual digital content, which speedily grows. In this paper, the analysis and semantic annotation of images are studied. The development of methods for colour image annotations based on learning represents the main contribution of the paper...
In order to improve the average recall rate and the average precision rate of image retrieval, an improved fusion algorithm of the weighted features is presented. Firstly,the shape features of images are extracted by using the moment invariant method based on 7 central moments. Meanwhile,the texture features of images are calculated by using the Gray-level Co-occurrence matrix. Then the elements of...
Representing bivariate scalar maps is a common but difficult visualization problem. One solution has been to use two dimensional color schemes, but the results are often hard to interpret and inaccurately read. An alternative is to use a color sequence for one variable and a texture sequence for another. This has been used, for example, in geology, but much less studied than the two dimensional color...
