SPEECH ENHANCEMENT USING PARTICLE FILTERS:A CRITICAL REVIEW
Journal Title: Indian Journal of Computer Science and Engineering - Year 2015, Vol 6, Issue 3
Abstract
Speech Enhancement refers to improvement in quality of a degraded speech signal in broad sense, however the aim is not only improvement of intelligibility but also overall quality, widely applied in de-reverberation, voice recognition systems, data matching in investigative fields and recovery of missing information i.e speech reconstruction. This paper presents a literature review of speech enhancement techniques, of all the methods available to us today ,we particularly concentrate on adaptive filtering method, due to successive implementation of Kalman filter in recent years and current research that has been carried on over particle filter this paper reviews the comparisons of the two. It has been observed that particle filters outperforms Kalman filters when it comes to non-linear ,non Gaussian noise removal.though the limitation is number of particle in particle filter.

COMPUTER SIMULATION OF BLOOD FLOW IN ARTERIES AFFECTED BY MULTIPLE ANEURYSM
The aim of this study is a numerical simulation of hemodynamics in blood vessels with multiple fusiform aneurysms. Dilation of 0.25 is considered. Using computational fluid dynamics, hemodynamic factors such as velocity...
Color Image Enhancement Techniques: A Critical Review
Image enhancement is one of the key issues in high quality pictures such as digital camera and HDTV. Since Image clarity is very easily affected by lighting, weather, or equipment that has been used to capture the image....
AN IMPROVEMENT IN LARSA AND ITS IMPLEMENTATION ON ALLOCATION OF SEATS TO CATEGORIES IN AN ORGANIZATION
In this paper, we propose modifications to LaRSA - a fast exact algorithm for the allocation of seat for the EU Parliament. This improvement shall reduce its run time by a considerable amount. Further, we apply this modi...
DETECTION AND CLASSIFICATION OF TUMORS IN CT IMAGES
Image segmentation is the process of partitioning a digital image into multiple segments or set of pixels. The objective of image segmentation is to group pixels into a prominent image region. In this paper, segmentation...
