A very low complexity frequency-domain analog speech scrambler having high-quality speech reconstruction is proposed. The scrambler uses frequency-response masking filter banks which have low computational complexity and narrow transition widths. The

Owing to the large amount of speckle noise and ill-defined edges present in echocardiographic images, computer-based boundary detection of the left ventricle has proved to be a challenging problem. In this paper, a Markovian level set method for boun

In emotion classification of speech signals, the popular features employed are statistics of fundamental frequency, energy contour, duration of silence and voice quality. However, the performance of systems employing these features degrades substanti

In this paper, a novel approach to the transcription of polyphonic signals is investigated. The method makes use of top–down analysis algorithm and bottom–up reconstruction of frequency contents of musical signals using a reference database that

As densities and data rates increase, accurate characterization of the read/write process becomes increasingly critical in magnetic/optical recording. In this paper, we propose an advanced synchronous characterization scheme which employs joint synch

In this paper, a novel feature-based image watermarking scheme is proposed. Zernike moments which have invariance properties are adopted in the scheme. In the proposed scheme, feature points are first extracted from host image and several circular pa

A novel robust audio watermarking scheme is proposed in this paper. In the proposed scheme, the host audio signals are segmented into frames. Two consecutive frames are assessed if they are suitable to represent a watermark bit. If so, frequency tran
