Image retrieval is analogous to conventional text-based querying of databases except that both the query and the retrieved data are in the form of images. For example, a query image of a mountain must retrieve images of mountains from a database of images. Such matches are done using features easily extracted from images such as colour, texture, shape and(More)
Machine based Gender classification is one of the challenging problem to the computer science researchers. The effortless ability exhibited by a two year kid for the same needs immense computation power for the computing machines. Many people attempted this problem by using different psychological characteristics such as handwriting, speech recognition,(More)
PURPOSE To compare the cancer detection rate in patients with raised serum prostate-specific antigen (PSA) or abnormal digital rectal examination (DRE) results between the 10-core and the 16-core biopsy techniques in an Indian population. METHODS Between November 2010 and November 2012, 95 men aged >50 years who presented to the Urology Department with(More)
This paper presents an approach and a system to let tutors monitor several important aspects related to online tests, such as learner behavior and test quality. The approach includes the logging of important data related to learner interaction with the system during the execution of online tests and exploits data visualization to highlight information(More)
In all speech communication settings the quality and intelligibility of speech is of utmost importance for ease and accuracy of information exchange. Kalman filter is an adaptive least square error filter that provides an efficient computational recursive solution for estimating a signal in presence of noises. Beamforming is another possible method of(More)
The paper presents a new speech enhancement approach for a single channel speech enhancement in a noise environment. In this method speech is mixed with real-world noises from babble, car and street environments. In this paper we proposed modified Kalman method for effective speech enhancement. The proposed method is compared to the traditional Spectral(More)
