object illumination
2.The achievements of researching on this system are of pioneer effect to the research on this field. And the achievements will promote the development of the study to achieve the real-time, accurate and applied effect in these field such as the realization of the real-time human-computer interaction, the multimodal I/O system platform, the assemble aid VR implement system based on view point, and the object recognition from images of various pose and illumination.
3.This paper presents a portable system designed for video monitoring based on TMS320C67xx,and takes a deep study on CMU’s moving object detection algorithm and the operator of morphology open operation filter. It gives out a moving object detection method,which combines frame difference,adaptive background subtraction and morphology filter. Some experiments prove the method given in this paper is fast,effective and robust to effect of illumination and noise.
4.With d/8 standard illumination/viewing geometry recommended by International Commission on Illumination (CIE), based on the theory of photometry and colorimetry and using self-scanning photodiode arrays as photoelectrical detector, a double light paths and multi-channel fast spectral measurement system for object surface color is designed. The system consists of integrating sphere, pulse light source, polychromator, photoelectrical amplifier, A/D converter and special-purpose computer, etc.
5.Abstract: Presents a new optical way of flow visualization realized through analyzing the elliptically polarized beam generated by superimposition of two orthogonal linearly polarized beams,while the polarization of every point in image changes according to the refraction index of the flow at every point, causing variation of illumination about every point of the image through analyzer, if one beam passes through the flow object and concludes from experimental results that this method is feasible because there is no interference between two orthogonal linearly polarized beams, and this method can generate more unambignous image than the method of Mach-Zehnder interferometer, and can be used in such fields as fluid mechanics,biological observation and microelectronics.
