Recently, several researchers have proposed using spatio-temporal filters for image motion analysis. For example, the optical flow field can be calculated from the output of a set of spatio-temporal filters. Some of the most popular spatio-temporal filters are the space-time Gabor filters, obtained by convolving a time varying image with a space-time Gabor function. Based on the cellular neural...

Colonoscopy is a popular procedure which used to detect an abnormality. Early diagnosis can help heal many patients. The purpose of this paper removing/reducing some artifacts improve the visual quality colonoscopy videos provide better information for physicians. This work complements series consisting three previously published papers. In paper, optic flow motion compensation, where number co...

To circumvent the problem of low signal-to-noise ratio (SNR) in event-related fMRI data, the fMRI experiment is typically designed to consist of repeated presentations of the stimulus and measurements of the response, allowing for subsequent averaging of the resulting data. Due to factors such as time limitation, subject motion, habituation, and fatigue, practical constraints on the number of r...

Edge preserved smoothing techniques has gained importance for the purpose of image denoising. A good edge preserved filtering is given by nonlocal-means filter than any linear model based approaches.The contributions are in two fold. First, this paper explores a refined approach of nonlocal-means filter by using robust estimation function rather than the usual exponential function for its weigh...

The article describes the developed software that made it possible to process a large amount of data from observations movement and parameters aquatic environment in Sea Azov, which was obtained during expeditionary research using ADCP hydrophysical probe, filtration procedure. filtering procedure significantly reduces spread amplitude fluctuations, which, turn, makes more adequately evaluate i...

The bilateral filter is a useful nonlinear filter which without smoothing edges, it does spatial averaging. In the literature, the effectiveness of this method for image denoising is shown. In this paper, an extension of this method is proposed which is based on complex wavelet transform. In fact, the bilateral filtering is applied to the low-frequency (approximation) subbands of the decomposed...

Inter-picture prediction in HEVC can be seen as a steady improvement and generalization of all parts known from previous video coding standards, e.g. H.264/AVC. The motion vector prediction was enhanced with advanced motion vector prediction based on motion vector competition. An inter-prediction block merging technique significantly simplified the block-wise motion data signaling by inferring ...
