Description: Automatic target detection in SAR image is the first stage in the ATR (Automatic Target Recognition) system. It is very important to improve the computing efficiency of the whole system. A conventional automatic target detection method is CFAR (constant false alarm rate) which is based only on the amplitude, discards the phase and thereby sacrifices half information of the SAR imagery. Almost each CFAR brings a large number of false alarms. 2L-IHP (two-look internal Hermitian product) is a new method which exploits the phase and amplitude information. In this paper, both CFAR and 2L-IHP algotithms are compared with an emphasis on 2L-IHP. The 2L-IHP algorithm for target detection is discussed briefly first. In order to apply it widely, it is modified to circumvent the constraint of the data. For polarimetric SAR images, PWF (Polarimetric Whitening Filter) is used to generate an image for target detection. According to ADTS data set, these algorithms are analyzed and evaluated respectively. C-、L- and P- band AIRSAR data are also processed, and some tentative conclusions are derived: Considering the penetrating ability of the microwave, L-band got the best detection accuracy of the three bands; HH polarization performed better for target detection than VV and HV polarization; Moreover, because more information is contained in polarimetric SAR data, here, we conclude that polarimetric SAR data have advantages over single polarized SAR data when they are applied for target detection. But all these conclusions need further validation.

Description: Virtual reality (VR) in education is a markedly present subject in research institutions
in many countries. This paper will discuss the application of VR techniques, including
the use of computer graphics and three-dimensional (3D) video production.
Stereoscopy is a key point for the visualization of these applications. The system
developed uses a 3D lens, a home camera, common video edition software, two low
cost projectors, light polarized filters and cheap 3D eyeglasses. During the 3D video
production, the aim was to evaluate all the involved process, since the elaboration of
scripts, video capture and projection until the costs to build the system. This is
important to demonstrate for educational institutions the advantages in adopting
resources of VR for the improvement of learning.

Description: 光学器件模型C++代码 可以仿真光学散射折射衍射-SCATMECH is an object-oriented C++ class library developed to distribute models for light scattering applications. Included in the library are models for diffuse surface scattering that predict the bidirectional reflectance distribution function (BRDF), codes for calculating scattering by isolated particles, and codes for reflection, transmission, and diffraction from gratings. Emphasis has been given to those diffuse scatter models which are physics-based and which predict the polarization properties of the scattered light. The library also includes a number of classes that may be useful for working with polarized light or the optics of thin films. The library is constructed to enable expansion of new models.
