Non-Parametric Estimation of a Single Inflection Point in Noisy Observed Signal
Detection of abrupt changes, including inflection points, in the observed noisy signals is an important and challenging problem in engineering and science. Several methods have been proposed to solve this problem and proved to be successful for specific applications. Yet, there is demand for new and general approaches that are applicable to broader range of applications. The change point detect...
متن کاملDetermination of height of urban buildings based on non-parametric estimation of signal spectrum in SAR data tomography
Nowadays, the TomoSAR technique has been able to overcome the limitations of radar interferometry techniques in separating multiple scatterers of pixels. By extending the principles of virtual aperture in the elevation direction, these techniques pay much attention in the analysis of urban challenging areas. Despite the expectation of interference of the distribution of buildings with different...
متن کاملNon-Parametric Field Estimation using Randomly Deployed, Noisy, Binary Sensors
The reconstruction of a deterministic data field from binary–quantized noisy observations of sensors which are randomly deployed over the field domain is studied. The study focuses on the extremes of lack of deterministic control in the sensor deployment, lack of knowledge of the noise distribution, and lack of sensing precision and reliability. Such adverse conditions are motivated by possible...
متن کاملNon-parametric Sub-pixel Local Point Spread Function Estimation
This work presents an algorithm for the local subpixel estimation of the Point Spread Function (PSF) that models the intrinsic camera blur. For this purpose, the Bernoulli(0.5) random noise calibration pattern introduced in a previous article [1] is used. This leads to a well-posed near-optimal accurate estimation. First the pattern position and its illumination conditions are accurately estima...
متن کاملSingle and Multiple F0 Contour Estimation Through Parametric Spectrogram Modeling of Speech in Noisy Environments
This paper proposes a novel 0 contour estimation algorithm based on a precise parametric description of the voiced parts of speech derived from the power spectrum. The algorithm is able to perform in a wide variety of noisy environments as well as to estimate the 0s of cochannel concurrent speech. The speech spectrum is modeled as a sequence of spectral clusters governed by a common 0 contour e...
