Voice Activity Detection Using Higher Order Statistics
A robust and effective voice activity detection (VAD) algorithm is proposed for improving speech recognition performance in noisy environments. The approach is based on filtering the input channel to avoid high energy noisy components and then the determination of the speech/non-speech bispectra by means of third order autocumulants. This algorithm differs from many others in the way the decisi...
متن کاملDevelopment of an automated detection system for microcalcifications on mammograms by using the higher-order autocorrelation features
The purpose of this work is to develop a new pattern recognition method using the higher-order autocorrelation features (HOAFs), and to apply this to our microcalcification detection system on mammographic images. Microcalcification is a typical sign of breast cancer and tends to show up as very subtle shadows. We developed a triplering filter for detecting microcalcifications, and the prototyp...
متن کاملWavelet Based Microcalcifications Detection in Digitized Mammograms
Detection of microcalcifications in mammograms has received much attention from researchers and public health practitioners in these last years. The challenge is to quickly and accurately overcome the development of breast cancer which affects more and more women through the world. Microcalcifications appear in a mammogram as fine, granular clusters, which are often difficult to identify in a r...
متن کاملDetection and Diagnosis of System Nonlinearities Using Higher Order Statistics
This paper is concerned with the statistical analysis of closed loop data for diagnosing the causes of poor control loop performance. Higher Order Statistical (HOS) techniques have been developed over the last two decades, but until now have not been applied to the area of process monitoring. The main contribution of this work is to utilize the higher order statistical tools such as cumulants a...
متن کاملBlind Detection of Digital Photomontage using Higher Order Statistics
The advent of the modern digital technology has not only brought about the prevalent use of digital images in our daily activities but also the ease of creating image forgery such as digital photomontages using publicly accessible and userfriendly image processing tools such as Adobe Photoshop. Among all operations involved in image photomontage, image splicing can be considered the most fundam...
