Journal ArticleDOI
Feature-bit-plane matching technique for estimation of motion vectors
TL;DR: In this paper, a fast block matching algorithm based on a feature bit-plane matching scheme was proposed, in which two types of transformed planes characterising the spatial distribution of pixel intensities of a frame are employed.
Proceedings ArticleDOI
An iterative procedure for matrix inversion in weighted least-square design of FIR filters
TL;DR: In this article, a new iterative procedure is developed for the inversion of the matrices involved in the design of an FIR filter, by expanding the inverse of a matrix as a convergent series, an updating formula for evaluating the inverse for each iteration is obtained.
Proceedings ArticleDOI
A low-complexity MMSE Bayesian estimator for suppression of speckle in SAR images
Rafat Damseh,M. Omair Ahmad +1 more
TL;DR: The experimental results demonstrate the effectiveness of the proposed despeckling scheme in providing a significant reduction in the speckle noise at a very low computational cost and simultaneously preserving the image details.
Proceedings ArticleDOI
Srnmfrb: A Deep Light-Weight Super Resolution Network Using Multi-Receptive Field Feature Generation Residual Blocks
TL;DR: The experimental results demonstrate the superiority of the super resolution network using the proposed residual block over the state-of-the-art light-weight super resolution networks in terms of objective and subjective metrics.
Proceedings ArticleDOI
A detection method of nasalised vowels based on an acoustic parameter derived from phase spectrum
TL;DR: The proposed method even with a simple classifier is superior in performance in comparison to that of the methods using Mel-frequency cepstral coefficients as a feature and Hidden Markov Modeling or Support Vector Machine as a classifier.
