چکیده

In this correspondence, we present new results on the reconstruction of two-dimensional signals from zero crossing or threshold crossing information. Specifically, we develop new theoretical results which state conditions under which two-dimensional bandlimited signals are uniquely specified to within a scale factor with this information. Unlike previous results in this area, our new results do not constrain the signals to be periodic or bandpass.

Reconstruction of Two-dimensional Signals from Threshold Crossings *

In this paper, we present new results on the reconstruction of two-dimensional signals from zero crossing or threshold crossing information. These results follow from our previous work on the reconstruction of twodimensional signals from one bit of Fourier transform phase. Experimental results illustrating image reconstruction from threshold crossings are included.

Hermite polynomials for signal reconstruction from zero-crossings. 1. One-dimensional signals - Communications, Speech and Vision, IEE Proceedings I

Generalised Hermite polynomials are employed for the reconstruction of an unknown signal from a knowledge of its zero-crossings, under certain conditions on its spatial/spectral width, but dispensing with the assumption of bandlimitedness. A computational implementation of the proposed method is given for one-variable (or one-dimensional) signals, featuring an application of simulated annealing...

Image Reconstruction from Zero-Crossings

In the computational theory of human vision, developed by D. Marr and his school, zero-crossings detection is proposed as one of the first stages of human visual information processing. The justif ication of this theory reguires that the zero crossings are rich in information about the original image. In a paper, T. Poggio, H.K. Nishihara and K.R.K. Nielsen stated that a successful extension of...

Signal Reconstruction from Zero-Crossings

We present a method for recovering (to within a constant factor) periodic , octave band-limited signals given the times of the zero-crossings. Recovery involves taking the singular-value decomposition of a size N2M matrix, where N is the number of zero-crossings within one period and M is product of the octave bandwidth and the period length. We also discuss approximate approaches which can be ...

EMG-based wrist gesture recognition using a convolutional neural network

Background: Deep learning has revolutionized artificial intelligence and has transformed many fields. It allows processing high-dimensional data (such as signals or images) without the need for feature engineering. The aim of this research is to develop a deep learning-based system to decode motor intent from electromyogram (EMG) signals. Methods: A myoelectric system based on convolutional ne...
