Path-space Motion Estimation and Decomposition for Robust Animation Filtering

Renderings of animation sequences with physics-based Monte Carlo light transport simulations are exceedingly costly to generate frame-by-frame, yet much of this computation is highly redundant due to the strong coherence in space, time and among samples. A promising approach pursued in prior work entails subsampling the sequence in space, time, and number of samples, followed by image-based spa...

Path-space Motion Estimation and Decomposition for Robust Animation Filtering SUPPLEMENTARY MATERIAL

We define our decomposition using Heckbert’s [Hec90] light path notation to classify light paths or families of similar light paths. We label the first vertex on the camera sensor E (“eye”), and denote the subsequent scattering vertices based on a classification of the underlying materials. We use the following notation: (D) diffuse, (R) specular (or glossy) reflection, (T) specular (or glossy)...

Empirical Mode Decomposition based Adaptive Filtering for Orthogonal Frequency Division Multiplexing Channel Estimation

This paper presents an empirical mode decomposition (EMD) based adaptive filter (AF) for channel estimation in OFDM system.  In this method, length of channel impulse response (CIR) is first approximated using Akaike information criterion (AIC). Then, CIR is estimated using adaptive filter with EMD decomposed IMF of the received OFDM symbol. The correlation and kurtosis measures are used to sel...

Motion Estimation and Motion - Compensated Filtering

This paper is concerned with methods to estimate 2-D motion in time-varying images for application to motion-compensated ltering. The approach is based on the minimization of objective functions that can be interpreted as energies of suitable Gibbs-Markov random elds. A exible class of cost functions is described that can be applied in a wide variety of speciic applications , including the esti...

Robust Estimation for Motion Parameters

The performance of least squares method ca'n be improved by changing the error metric so that points which lie far from the bulk of data do not influence the final value—that is to reject the outliers. In this paper, the combination of two robust estimators are used to obtain motion parameters of a camera from matched image features. Results obtained show that the robust estimator has the abili...
