In this paper, we present a parallel algorithm for edge detection based on Infinite Impulse Response filter (IIR filter). In particular, the Infinite size Symmetric Exponential Filter (ISEF) that is an optimal IIR filter and computationally efficient smoothing filter is studied. The proposed algorithm exploits efficiently all aspects of potential parallelism (spatial parallelism, temporal paral...

Temporal difference (TD) algorithms are attractive for reinforcement learning due to their ease-of-implementation and use of “bootstrapped” return estimates to make efficient use of sampled data. In particular, TD(λ) methods comprise a family of reinforcement learning algorithms that often yield fast convergence by averaging multiple estimators of the expected return. However, TD(λ) chooses a v...

In this work, we consider the adaptive Wiener filtering of noisy images and image sequences. We begin by using an adaptive weighted averaging (AWA) approach to estimate the second-order statistics required by the Wiener filter. Experimentally, the resulting Wiener filter is improved by about 1dB in the sense of peak-to-peak SNR (PSNR). Also, the subjective improvement is significant in that the...

The trilateral filter is a nonlinear filter which performs averaging without concentrating on smoothing edges. Selection of the filter parameters is an important issue. A spatial nonlinear filter has been implemented based on local neighborhood about a pixel ) , ( y x f to reduce Gaussian and Impulse noise in images. Our approach is to remove universal noise automatically from synthetic images ...

Argon laser induced event related responses to pricking pain (first pain) were recorded. The different recording parameters (recording site, filter setting, averaging technique), quantification parameters (amplitude, power) and variability between successive recordings were studied. The single responses were large, and averaging of 16-32 single trials was sufficient to obtain reliable averaged ...

Fossil fuel carbon dioxide (CO2ff), the main driver of global warming and climate change, is often co-emitted with nitrogen oxides (NOx) precursors to ground-level ozone from anthropogenic sources like power plants or vehicles. In urban suburban areas, satellite-based NO2 can be used as a proxy track emissions CO2ff. Because NO2's shorter lifetime, plumes are more distinguishable backgrounds se...

The purpose of this study is to establish the technique for estimating optical flow with high accuracy and robustness using gradient-based method with local optimization. To obtain high accuracy, we should understand error sources and how to reduce the errors. We proposed error reduction techniques for gradient measurement error which are a spatiotemporal median filter to reduce sensor noise an...

We present a particle filter construction for a system that exhibits time-scale separation. The separation of time-scales allows two simplifications that we exploit: i) The use of the averaging principle for the dimensional reduction of the system needed to solve for each particle and ii) the factorization of the transition probability which allows the Rao-Blackwellization of the filtering step...

in this paper the substantiation of the method of full averaging for fuzzy differential inclusions is considered. these results generalize the results of [17, 20] for differential inclusions with hukuhara derivative and of [18] for fuzzy differential equations.
