With the introduction of information theory in the middle of the 20th century, the concept of noise came to be contrasted with signal. The exhibition Noise to Signal mainly consists of two projects that highlight the relative nature of these terms.

Application of energy difference spectrum of singular value in signal noise reductio
In view of problem that the order of effective rank of matrix reconstruction is difficult to determine in singular value decomposition for noise reduction, a novel signal noise reduction method based on energy difference spectrum of singular value was ...

An Effective Computational Ghost Imaging Based on Noise Estimation and Elimination
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

Use of data permutation to reduce the peak-to-average power ratio of an OFDM signal
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

Efficient method for DCT-domain image arbitrary downsampling
A novel approach to resize Images with m/n resizing ratio in the DCT domain,was proposed which expoits the relationship of DCT coefficients between m 2input blocks and n 2output blocks.Experimental results confirm that the scheme performs about 0.5dB ...

KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Time-Domain Sparsity-Based Bearing Fault Diagnosis Methods Using Pulse Signal-to-Noise Ratio [PDF]
A fast and automated technique is crucial for bearing faults diagnosis during operation. To circumvent the intricacies of signal spectrum analysis, a diagnostic method named the pulse signal-to-noise ratio (PSNR) test is proposed by exploiting the time ...

PSNR Improvement Using Different Prediction Coding
Differential Pulse Code Modulation (DPCM) is one of the predictive coding techniques. The number of previous pixels employed in the estimate operation is referred to as the order of the predictor. Predictor using one pixel for estimation is called “first
