Comparative Analysis of Filters for Cancellation of Power-line-interference of ECG Signal [PDF]
International Journal Bioautomation, 2019 Filtering noises/artifacts from the electrocardiogram (ECG) can sustain the efficient clinical decision making. Comparative analysis of several filtering techniques is proposed: two adaptive noise cancellation techniques, Least Mean Square (LMS ...

Pertanika Journal of Science and Technology, 2022 Audio steganography is implemented based on three main features: capacity, robustness, and imperceptibility, but simultaneously implementing them is still a challenge. Embedding data at the Least Significant Bit (LSB) of the audio sample is one of the most implemented audio steganography methods because the method will give high capacity and ...

An Effective Computational Ghost Imaging Based on Noise Estimation and Elimination
IEEE Access, 2020 To improve the quality of ghost image, we propose an efficient computational ghost imaging method in this article. The primary idea is to estimate the noise value of the ghost image by analyzing and eliminating the source of the noise. The innovativeness

Image Compression using Orthogonal Wavelets Viewed from Peak Signal to Noise Ratio and Computation Time [PDF]
International Journal of Computer Applications, 2012 Uncompressed image data requires considerable storage capacity and transmission bandwidth. Despite rapid progress in mass-storage density, processor speeds, and digital communication system performance, demand for data storage capacity and data transmission bandwidth continues to outstrip the capabilities of available technologies.

Use of data permutation to reduce the peak-to-average power ratio of an OFDM signal
, 2002 A set of fixed permutations is used in this paper to reduce the peak-to-average power ratio (PAR) of an orthogonal frequency division multiplexing (OFDM) signal. For this technique, K - 1 interleavers are used to produce K - 1 permuted sequences from the
