Histogram search characterizes an image by its color distribution. It represents a popular mean of feature representation in computer vision. In This paper, we developed an efficient algorithm for image searching based on matching of Histogram using fuzzy sets. We used Fuzzy Sets in This paper for performing Image searching efficiently. We investigated histogram search methods in two different ...

In this paper, an improved reversible data hiding scheme is proposed . In the method proposed by us , it apply expansion embedding , which will adaptively takes care of local specifities of image content. In our method , it classify pixels based on their predicted value and pixels prediction errors. By applying expansion embedding to the pixels prediction errors and by considering their immedia...

The conventional color histogram retrieval method is prone to lo se the spatial information of colors. This paper proposes a novel color histogram approach for image retrieval. The histogram is built over groups of circular rings over the image. It keeps the advantages of the robust to the image rotation and scaling of the traditional histogram and incorporates the spatial information of pixels...

Most of the natural textures are non-homogenous and stochastic by nature. In many cases these textures are also directional. In this paper we present a method for the retrieval of the non-homogenous directional textures. This method is directional histogram and it represents the directional distribution of the texture. The histogram can be formed using either directional filtering method or Hou...

We propose a new Monte Carlo technique in which the de-generacy of energy states is obtained with a Markovian process analogous to that of Metropolis used currently in canonical simulations. The obtained histograms are much broader than those of the canonical histogram technique studied by Ferrenberg and Swendsen. Thus we can reliably reconstruct ther-modynamic functions over a much larger temp...

Histogram Equalization is a contrast enhancement technique in the image processing which uses the histogram of image. However histogram equalization is not the best method for contrast enhancement because the mean brightness of the output image is significantly different from the input image. There are several extensions of histogram equalization has been proposed to overcome the brightness pre...

This study aims to increase the retrieval efficiency of proposed image retrieval system on the basis of color content. A new idea of feature extraction based on color perception histogram is proposed. First, the color histogram is constructed for HSV image. Secondly, the true color and grey color components are identified based on hue and intensity. The weight for true and grey color components...
