The local feature descriptors have received more attention due to the effectiveness in the field of face recognition. The existing LTrP method works based on the first order derivatives along horizontal and vertical directions. This LVP method demonstrates the relation between the center pixel and its neighbor pixels. The feature vector gets increased and the recognition rate gets reduced due to the...
Speech is one of the most promising models through which various human emotions such as happiness, anger, sadness, and normal state can be determined, apart from facial expressions. Researchers have proved that acoustic parameters of a speech signal such as energy, pitch, Mel frequency Cepstral Coefficient (MFCC) are vital in determining the emotion state of a person. There is an increasing need for...
In this paper, noise variance is estimated from the noisy spectrum using the proposed noise estimation algorithm. In addition, the speech signal is enhanced by the modified modulation magnitude estimation (MMME)-based spectral subtraction algorithm. Chi-square distribution-based noise estimation algorithm is proposed in this work. During the speech presence period, the noise variance is estimated...
Wimax is an broadband wireless technology based on IEEE 802.16. It is very helpful and cheaper than other possible solutions. It is purely based on the 4G technology for the upcoming generation. In wireless technology the major problem is speed, Quality of Service, data rates in order to overcome that they going for some valuable technology. In this paper we consider WIMAX and WLAN for controlling...
Speech enhancement techniques are widely used to enhance the quality and intelligibility of the speech signal in the noisy environment. Conventional noise reduction methods introduce more residual noise and speech distortion. The existing algorithms fail when there are abrupt changes in the noise level. To overcome the shortcomings of the conventional methods, improved noise tracking algorithm is...
Palmprint recognition using Biometrics is one of the emerging technologies, which recognizes a person based on the principle lines, wrinkles and ridges on the surface of the palm. These line structures are stable and remain unchanged throughout the life of an individual. More importantly, no two palm prints from different individuals are the same, and normally people do not feel uneasy to have their...
A novel method for fingerprint recognition, using SVM has been proposed in this paper wherein large sample size problem is reduced to small sample size problem using support vectors. Support Vector Machines (SVMs) have been recently proposed as a new classifier for pattern recognition. This paper presents an effective method for fingerprint classification using data mining approach. Initially, it...
The process of repairing the damaged area or to remove the specific areas in a video is known as video inpainting. To deal with this kind of problems, not only a robust image inpainting algorithm is used, but also a technique of structure generation is used to fill-in the missing parts of a video sequence taken from a static camera. Most of the automatic techniques of video inpainting are computationally...
