A variety of approaches to achieve automatic grading of brain tumors has surfaced in the recent past. In this paper, we propose a technique for automatic classification of brain tumor based on multi-level 3D wavelet analysis. A wavelet analysis is capable of performing multiresolution analysis under different environments i.e. it is rotation and direction invariant. The brain tumor MR images are decomposed...
Emotion detection from speech has been realized to provide benefits for more natural human-machine interaction. To detect the emotion from speech signal, an abundantly long continuous speech segment is needed. This paper proposed a navel approach for emotion detection based on relative amplitude of speech signal. Relative amplitude reduces bias of glottis mutation of speech wave amplitude and obtains...
