The invention relates to a system and method for detecting, locating and identifying objects located above ground or below ground in an area of interest, comprising an airborne vehicle which circumscribes the area of interest and which includes a built-in radar having an antenna with a respective transmitter and receiver, signal-processing means, data-storage means and graphical interface by: Automatic road extraction from remote-sensing imagery plays an important role in many applications. However, accurate and efficient extraction from very high-resolution (VHR) images remains difficult because of, for example, increased data size and superfluous details, the spatial and spectral diversity of road targets, disturbances (e.g., vehicles, shadows of trees, and buildings), the Author: Li Chen, Qing Zhu, Xiao Xie, Han Hu, Haowei Zeng.
surements, though, are done and recorded in discrete time. Thus the SOI time series, as well as most climatic and other geophysical time series, are available in dis-crete time. Analysis in the Time Domain Versus the Spectral Domain  Two basic approaches to time series analysis are associated with the time domain or the spectral domain.

Hyperspectral Imaging: Techniques for Spectral Detection and Classification is an outgrowth of the research conducted over the years in the Remote Sensing Signal and Image Processing Laboratory (RSSIPL) at the University of Maryland, Baltimore County.
It explores applications of statistical signal processing to hyperspectral imaging and further develops non-literal (spectral) techniques for subpixel detection Cited by: We propose a method of identifying bio-signature spectral lines in light of known extrasolar planets based on Fourier spectroscopy in the infrared, using an off-center part of a Fourier.
A Novel Method of Detecting Lines on a Noisy Image Daniel Lin A thesis submitted in partial fulﬁllment for the method of detecting lines In this section, we give a formal problem deﬁnition, provide the theory of line detection, and present the existing method for line detection.

Raj, M. Senthil Vadivu. Variants of this method have previously been used to search for stellar, brown dwarf, and even planetary companions. We show that the direct spectral detection method can detect companions as late as M-type orbiting A0 or earlier primary stars in a single epoch on small-aperture telescopes.

Boitsov. Along with finite differences and finite elements, spectral methods are one of the three main methodologies for solving partial differential equations on computers. This book provides a detailed prese. The comparable amplitude of the event with the background noise, even when the data are bandpassed between 5 and 55 Hz, causes the STA/LTA method to fail in detecting this event.
However, the elevated spectral content of the event with respect to that of the background noise makes the PSD method succeed in detecting this weak by: Spectrogram Enhancement By Edge Detection Approach Applied To Bioacoustics Calls Classification W.B.
Hussein*, Although the base spectral subtraction method is very simple and efficient, it assumes the noise to including those of noise as well as very weak.
A method in detecting distant objects and recording their features and properties by analysis of electromagnetic waves reflected from their surfaces.
False-color image A computer image that assigns distinctive colors to different wave lengths of light reflected from a distant object, delineating surface features; used frequently in satellite images of Earth from space. In order to study the spectral line shift property of prism-dispersive imaging spectrometer, the influencing factors and mechanisms of spectral line shift were presented, and the mathematical.

In the finite element community, a method where the degree of the elements is very high or increases as the grid parameter h decreases to zero is sometimes called a spectral element method. Spectral methods can be used to solve ordinary differential equations (ODEs), partial differential equations (PDEs) and eigenvalue problems involving differential equations.
Spectral Method of Analysis Multiple Choice Questions & Answers. Spectroscopy deals with interaction of electromagnetic radiation with matter. What is the speed of this radiation in vacuum in m/s. a) 6 x 10 8 b) 5 x 10 8 c) 7 x 10 8 d) 3 x 10 8. Answer: d. Explanation: Speed of light is also the speed of all electromagnetic radiations.
Most damage detection methods have difficulty in detecting damage using only measurement data due to the existence of external noise. It is necessary to reduce the noise effect to obtain accurate information and to detect damage by the output-only measurement without baseline data at intact state and input data.
This work imported the power spectral density estimation (PSE) of a signal to Cited by: 2. This method treats both (the questioned and known) spectra as vectors and calculates the spectral angle between them. This method is insensitive to illumination since the SAM algorithm uses only the vector direction and not the vector length.
The result of the SAM classification is an image showing the best match at each pixel. is then modeled by extracting both spectral and spatial features.
Our algorithm has been find the video pictures based on hough transform. Hough has been proposed an interesting and computationally efficient method for finding the lines in picture.
