This paper studies a new technique that characterizes a speaker by the difference between the speaker and a cohort of background speakers in the form of feature-space maximum a posteriori linear regression (fMAPLR). The fMAPLR is a linear regression function that projects speaker dependent features to speaker independent ones, also known as an affine transform. It consists of two sets of parameters,...
In this paper, a voice conversion system that converts spoken vowels into singing vowels is proposed. Given the spoken vowels and their musical score, the system generates singing vowels. The system modifies the speech parameters of Fundamental frequency (F0), duration and spectral properties to produce singing voice. F0 contour is obtained using F0 fluctuation information from training singing voice...
In order to improve the invisibility and the robustness of semi-fragile watermarking, the paper first brings up the idea which embedding watermark based on the attackspsila characteristic, brings forward the region segmentation operator and the double-step embedding method. The paper puts forward the characteristic and its representation in DWT transform domain based on visual features model, and...
An image classification method based on wavelet transform was brought up, and it adopted the human visual features model and analyzed the image parameter characteristics in smooth and texture regions. It put up optimum carrier image selecting method of original image to be hidden while analyzing the differences between the carrier and being hidden image. On the premise of setting a threshold, it made...
