We describe in this paper the different approaches tested for the Photo Annotation task for CLEF 2011. We experimented state of the art techniques, by proposing late fusions of several classifiers trained on several features extracted from the images. The classifiers are SVMs and the late fusion is a simple addition of classification probabilities coming from the SVMs. The results obtained plac...

Most existing digital watermarking algorithms, which are based on the Discrete Wavelet Transform, are not robust to geometric distortions, even if for some special distortions, such as multiples of 90◦ rotation of integers and image flipping, which change the location of pixels but have no effect on the value of the image. Therefore, to solve the problem, according to Haar wavelet transform the...

SIFT Feature with Relevance Feedback for Image Retrieval Written by Administrator Wednesday, 16 March 2011 08:52 Last Updated Monday, 21 March 2011 07:32 In this paper, we used the Scale Invariant Feature Transform (SIFT) feature for image retrieval. SIFT descriptors are invariant to image scaling, transformation,rotation and partially invariant to illumination changes and affine, gives the loc...

A method for automatic building extraction from high resolution satellite image is given. First, the image is segmented by using the split and merge segmentation. Then the segmented image is filtered by applying different filters. After filtering the output raster image is converted into vector image and then the buildings are extracted on the basis of area from the vector image. Finally, the c...

ImageCLEF’s Wikipedia Image Retrieval task provides a testbed for the system-oriented evaluation of multimedia and multilingual information retrieval from a collection of Wikipedia images. The aim is to investigate retrieval approaches in the context of a large and heterogeneous collection of images (similar to those encountered on the Web) that are searched for by users with diverse informatio...

abstractin this article, iranian society in the 80s is analyzed in terms of its prevailing insights using the theory of reflection in the sociology of cinema. this theory, which considers art as a mirror for society, permits researcher to study the predominant perceptions of the period under investigation. this is done through assessment of the image of hero shown in its cinema. moreover, the g...

Lee Non-blind image deconvolution is a process that obtains a sharp latent image from a blurred image when a point spread function (PSF) is known. However, ringing and noise amplification are inevitable artifacts in image deconvolution since p...

The ‘Abb®sid caliphs al-Ma’m‚n and al-Mu‘ta◊im, who between them reigned from 198 to 227 A.H. (813-842 A.D.) are best-known to historians of philosophy for two things. First, they supported a massive translation project that had already begun in the previous century with al-Ma’m‚n’s grandfather, al-Man◊‚r. The result was that many of the most important works of Greek philosophy and science were...
