A new variable step LMS algorithm for transform domain
TL;DR: The proposed new variable step LMS algorithm has the advantage of a variable step-size and the decorrelation of the input signal for increased speed of convergence and is compared with other time domain and transform domain implementations.
Proceedings Article
Evaluation of potentials for local transform domain filters with varying parameters
TL;DR: Monte Carlo simulations of a set of local transform domain filters are performed to evaluate how much the selection of filter parameters affect the filter performance and how far their performances are from that of the ideal Wiener filter.
Proceedings ArticleDOI
Depth map occlusion filling and scene reconstruction using modified exemplar-based inpainting

TL;DR: This paper presents an efficient hole filling and damaged region restoration method that improves the quality of the depth maps obtained with the Microsoft Kinect device by exploiting the correlation between color and depth values in local image neighborhoods.
Proceedings ArticleDOI
LMS adaptive filter with optimum step-size for tracking time-varying channels
TL;DR: An algorithm which adaptively adjust the step-size of the LMS toward its optimum value, such that the steady-state MSE is minimized.
