In this paper the problem of no-reference measurement of the contrast of image elements (objects and background) for complex multi-element images is considered. A generalized description of the weighted contrast of the image elements was proposed. New definitions for the weighted contrast of the image elements are proposed. A comparison of the proposed and known definitions of weighted contrast was...
The problem of image contrast enhancement was considered. The histogram-based method for image contrast enhancement in automatic mode on the basis of the contrast distribution function at the boundaries of image elements (objects and background) for the different definitions of contrast kernels is proposed. A comparison of the proposed and known histogram-based methods of image contrast enhancement...
The problem of no-reference measurement of image contrast is considered. The method of no-reference quantitative assessments of image contrast using different contrast kernels is proposed. A comparison of the proposed and known histogram-based methods of image contrast measurement of was carried out. Examples to illustrate the effectiveness of proposed method are given.
Understanding how populations of artificial neurons in neuron models encode and decode signals, is a primary task in control problems. Since the neurons use spiky signals, it is first necessary to understand what these signals mean in terms of carrying a sensory input. Also, to apply the concepts in control theory, we prefer analog form of these signals. In this work, we try to find an optimal filter...
In this paper some measures of similarity of speech signals fragments, which are used for their recognition, the results of their comparison and efficiency of application are considered.
In this paper the features of use continuous and discrete wavelet transforms for processing and analysis of experimental signals of rail fault detection are considered.
