A NEW ITERATIVE SPEECH ENHANCEMENT SCHEME BASED ON KALMAN FILTERING



ABSTRACT

A new iterative speech enhancement scheme that can be seen as an approximation to the Expectation-Maximization (EM) algorithm is proposed. The algorithm employs a Kalman filter that models the excitation source as a spectrally white process with a rapidly time-varying variance, which calls for a high temporal resolution estimation of this variance.

An Empirical Study of Test Case Filtering Techniques Based on
Exercising Information Flows-IEEE TRANSACTIONS ON SOFTWARE ENGINEERING, VOL. 33, NO. 7
Abstract—
Some software defects trigger failures only when certain local or non local program interactions occur. Such interactions are modeled by the closely related concepts of information flows, program dependences, and program slices. The latter concepts underlie a 78variety of proposed test data adequacy criteria, and they form a potentially important basis for filtering existing t ....etc

ABSTRACT
Classical linear image restoration techniques assume that the linear shift invariant blur, also known as the point - spread function (PSF), is known prior to restoration. In many practical situations, however, the PSF is unknown and the problem of image restoration involves the simultaneous identification of the true image and PSF from the degraded observation. Such a process is referred to as blind deconvolution. This paper presents ....etc

IMAGE ENHANCEMENT TECHNIQUES

SUBMITTED BY
INTRODUCTION
Image enhancement widely used in computer graphics.
It is the sub areas of image processing.
The principle objectives of image enhancement techniques is to process an image so that the result is more

suitable than the original image for a specific application .
METHODS FOR IMAGE ENHANCEMENT
Image enhancement techniques can be divided into two broad categories:

1.Spatial domain methods .
2 Frequency domain methods.
SPATIAL DOMAIN METHODS ....etc

IMAGE ENHANCEMENT TECHNIQUES USING FREQUENCY DOMAIN FILTERING


Image Enhancement?
It is the process of making an image more pleasable than the original image.

Why needed?
Noise introduced in to the image, out-of focus , atmospheric conditions, latency of imaging hardware.

Applications

Medical imaging.
Satellite imaging.
Material testing in industries.
Fingerprint identification.
Printing and publishing industry.

Conclusion

Thus, image enhancement techniques in frequency domain improves the ....etc

Abstract
Extracting minutiae from fingerprint images is one of the most important steps in automatic fingerprint identification and classification. Minutiae are local discontinuities in the fingerprint pattern, mainly terminations and bifurcations. In this work we propose two methods for fingerprint image enhancement. The first one is carried out using local hist ....etc
