Spectrum extraction plays a crucial role in two-dimensional spectrum data processing. One of the most important spectrum extraction methods is profile fitting algorithm. In this article we studied the spectrum profile fitting method of non-Gaussian model. The general solution methods always have poor adaptability and some limitation, in order to approximate spectral profiles better, we introduced...
Synthetic aperture radiometer has the potential to meet the spatial resolution requirement of passive microwave remote sensing from space. This paper introduces a prototype of two-dimensional imaging radiometer at millimeter wave (MMW) band. A G Matrix calibration approach and an iterative gradient inversion method are presented to obtain the brightness temperature image. Total least squares (TLS)...
In an embedded system, the hardware resources are limited. In order to obtain such traffic information as traffic volume and vehicle speed in an embedded system, a series of efficient video processing algorithms and optimization techniques are proposed. The key algorithm to detect vehicles is the background subtraction method, in which the approximated median filter is applied to obtain the simulated...
