Single-sensor digital cameras capture image by covering the sensor surface with a color filter array(CFA) such that each sensor pixel only samples one of three primary color values
three color is R(red)
G(green) and B(blue). To render a full-color image
need an interpolation process commonly referred to as CFA demosaicking
is required to estimate the other two contributions for producing a full-color image. But
the noise in imaging sensors not only corrupts the color filter array
at the same time introduces artifacts during the color interpolation step and influence quality of images. In order to acquire high quality full-color images
adopt a sort of viable and effective interpolation algorithm based on gradient
at the time of removing the noise
reserve image border and detail information clearly. 2012 IEEE.

The new method has been proposed based on the comparison and analysis of the traditional methods for measuring rotating speed. It can guarantee real-time property with radial gratings at measuring low speed. It is clearly explained that the fundamental principle for measuring rotating speed and characters of the method and presented the constitution of the system hardware and the process flows.

In the field of robot vision
edge feature based stereo matching algorithm can reconstruct the targets with clear contours
which needs accurate and continuous target edges been extracted. In the paper
the smoothing filter operator was designed based on the discrete criteria of edge extraction and its correspondence optimal linear filter. Edge extraction was carried out incorporated the nonmaximum suppression and two thresholds techniques. The discrete criteria based multi-scale edge extraction method was studied with full use of the multi-scale character of the edge information. The detected multi-scale edges were synthesized to obtain the accurate and continuous single pixel wide edge. Then an edge feature based stereo matching algorithm was proposed to obtain 3D information of target. The experimental results demonstrate that the method can effectively suppress disturbance in outdoor environment and reconstruct target contour clearly. (2011) Trans Tech Publications.

The automotive power steering units must be taken performance test after they are integrated assembly and then left the factory if it is qualified.Because its internal flow channel is very complicated and the residual hydraulic oil can not be eleminated clearly.So we can set up a 3D model flow channel based on CATIA and use FLUENT software to analysis the key flow channel
analysing it's pressure distribution and velocity vector diagram then get the real reasonable resluts
which can provide the basic for the ejector designing. (2011) Trans Tech Publications.

This paper present a fast and simple medical image enhancing method based on locally redistributed histograms
which can enhance the contrast ratio of medical images efficiently. Compared with conventional enhancing methods
it can process images more clearly and suppress noise more efficiently
especially for medical images. 2010 IEEE.

An experimental EUVL system has been developed to investigate EUV imaging system design
component fabrication
assembly technique and experimental process. The system includes a laser produced plasma (LPP) source
an ellipsoidal condenser
a transmission mask
a reduced projection optics
and vacuum system. We designed a 10:1 reduction projection optics using Schwarzschild system with spherical mirrors to achieve 0.1m resolution. The Schwarzschild optics coated with Mo/Si multilayers was assembled with wavefront error (WFE) of 0.014 waves RMS at 632.8nm wavelength under computer-aided alignment method. Using this system a fine pattern of less than 0.25m covering a 0.1mm diameter image field of view was clearly replicated on resist-coated wafer.

The results of design effort for infrared zoom systems using all reflective aspheric surfaces are described. Issues such as the paraxial design theory and aberration balancing are discussed in detail. Two all reflective zoom optical systems are disclosed clearly. Both of them are to be used with uncooled infrared detectors. The first design is an unobscured three mirror zoom system without any intermediate image
and the second is a three mirror system with central obscuration which forms an intermediate image. With the design theory further developed
this kind of systems can be designed for cooled infrared detectors
for which cold stop matching is an important issue. 2006 SPIE-OSA.
