Deconvolution01:20

Deconvolution

676
Deconvolution, also known as inverse filtering, is the process of extracting the impulse response from known input and output signals. This technique is vital in scenarios where the system's characteristics are unknown, and they must be inferred from the observable signals.
Deconvolution involves several mathematical techniques to derive the impulse response. One common approach is polynomial division. In this method, the input and output sequences are treated as coefficients of...

Reconstruction of Signal using Interpolation

829
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

Residuals and Least-Squares Property

The vertical distance between the actual value of y and the estimated value of y. In other words, it measures the vertical distance between the actual data point and the predicted point on the line
If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.
The process of fitting the best-fit...

Reducing Line Loss01:18

Reducing Line Loss

440
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

    • Computer Vision
    • Neuroscience
    • Machine Learning

    Background:

    • Deep neural networks excel at image restoration but can lack stability.
    • Human brain processing shows similar stimuli evoke similar neural signals.
    • Conventional networks don't leverage this neurological property, leading to unstable internal propagation.

    • To incorporate principles of human brain visual processing into deep learning models.
    • To improve the reliability and performance of image restoration techniques.

    Main Methods:

    • Developed a (stacked) non-local auto-encoder exploiting self-similar information in natural images.
    • Constrained differences between hidden representations of non-local similar image blocks during training.
    • Introduced a collaborative stabilization step for rectifying forward propagation in image restoration tasks.

    Main Results:

    • The non-local auto-encoder demonstrated enhanced stability by ensuring similar inputs yield similar network propagation.
    • The collaborative stabilization step further improved the accuracy of image restoration.
    • Extensive experiments in image denoising and super-resolution confirmed the method's effectiveness.

    Conclusions:

    • The proposed non-local auto-encoder offers a stable and effective approach to image restoration.
    • Mimicking human brain's response to similar stimuli enhances deep learning model performance.
    • The method provides a reliable deep model for various image restoration applications.
